Key Words: History, Mexico, Diptera, Taxonomy.

Previously to this work, Papavero and Ibáñez-Bernal (2001) published about the entomologists and their works on Mexican Diptera before the publication of the " Biologia Centrali-Americana ", presenting as well the list of Diptera taxa collected in this country and described by them. In this second part of the History of Mexican Dipterology, the specific scope is to present some historical data of the contributors to the great work carried out by Godman and Salvin, resulting in the publication of the " Biologia Centrali-Americana ", contributing the list of all Mexican Diptera species described in it and the actual taxonomic status. Both, the first part and the present work get together all the Diptera taxa described before the XX century based in specimens collected in Mexico.

1. GENERAL REMARKS

Osbert Salvin, the second son of Mr. Anthony Salvin, an eminent architect, was born at Finchly in 1835 and educated at Westminster and Cambridge. He developed a very early taste for natural history.

Frederick DuCane Godman, third son of Joseph Godham, of Park Hatch, Surrey, was born in January 1834, and at the age of ten went to Eaton, but three years later a very severe attack of what was then called low fever necessitated his removal, and for some years he was unable to work at all. When his health was sufficiently reestablished, he received instructions from tutors until he was eighteen years old, when he then made a trip to the Mediterranean and the Black Sea. During the time spent at home he interested himself in natural history, paying special attention to British mosses and ferns.

In 1853 Godman entered Trinity College, Cambridge, as an undergraduate, and Salvin in the following year went to Trinity Hall, of which college he became a scholar; he graduated as a Senior Optime in the mathematical tripos and was afterwards made an Honorary Fellow. With similar tastes, it was only natural that they met and soon became fast friends, thus forming that close intimacy which only terminated with Salvin's death on June 1st, 1898.

During their College days Salvin and Godman made frequent expeditions together to the fens and other places in the neighborhood of Cambridge, to collect birds's eggs and Lepidoptera. They also spent their leisure hours in Baker's shop, a well known bird stuffer in the Trumpington Road, skinning and setting up birds- an experience which they found of great service afterwards when in Central America and on other expeditions.

In 1857, Salvin made a bird-nest expedition with Rev. H. B. Tristram and Mr. W. H. Simpson through Tunisia and eastern Algeria, in which Godman was to have joined them, but a hunting accident laid him up for some weeks and prevented him from accompanying them. Later in the year when Godman was sufficiently recovered from his accident, he went with his brother Percy to Bodö on the coast of Norway; there they remained for some weeks exploring the surrounding country. Taking the steamer northward to the Atlen River, they crossed Lapland on foot to Haparanda, on the Gulf of Botnia. Before returning home they visited Stockholm, St. Petersburg and Nijni-Novgorod.

In the Autumn of 1857, Salvin paid his first visit to Central America, in company with Mr. George Ure Skinner, a collector of birds and orchids, which he had brought from that country on previous expeditions. Salvin undertook the journey at the request of Messrs. Price & Co., to examine and report upon the nuts of a palm which it was thought might be used in the manufacture of candles. The palm-nuts, however, proved to be useless for practical purposes, and Salvin spent the remainder of his time traveling through the country and making a collection of birds and insects. He reached Belize in December 1857, and after spending a few days there, proceeded down the coast to Izabal and thence by easy stages to Guatemala City, making Dueñas, 30 miles southwest to the capital, his headquarters for six months. Salvin made two excursions to the Pacific Coast region and one to the lake of Atitlán in the "Altos". Leaving the country towards the end of June 1858, he returned to England via San José and Panama.

In August 1861, Godman joined Salvin on his third expedition to Guatemala, and, after spending three weeks in Jamaica en route, they landed at Belize; thence taking their passage in a coasting schooner they arrived at Izabal on the Golfo Dulce. There they remained a few days, making preparations for their journey engaging Indians and mules to transport themselves and their baggage to the interior.

Crossing the Mico range of mountains, they spent a few days at Quirigua. From Quirigua they again took the mule track through the valley of the Motagua river to Zacapa and thence to Guatemala City. They spent a day or two at the capital and then proceeded to Dueñas, where they remained some weeks at the house of a Mr. William Wyld, a friend of Salvin's. Their time was devoted to collecting, chiefly in the high forests of the Volcán de Fuego, the peak of which they ascended, and Godman made a separate expedition to Escuintla, in the Pacific Coast region.

After their stay in Dueñas, they retraced their steps to the capital, and crossing the Chuacus range into the plain of Salama, they took abode at the Hacienda de San Gerónimo. There they resided for some weeks, finding several species of birds and insects which they had not previously obtained. From San Gerónimo they went to Cobán, and, after spending some time collecting in the neighborhood, they visited Cubilquitz and Choctum in the low damp forest of Alta Vera Paz. At Cubilquitz, Godman experienced a sharp attack of fever, which obliged him to remain for some days at Cobán to recover, and prevented him accompanying Salvin on his long and arduous journey on foot to Petén.

When Godman had recovered sufficiently, he returned to San Gerónimo and then went to Buenaventura, on the upper waters of the Motagua river, called the Río Grande, where he employed Indians to poison some nine miles of the water in order to make a collection of the fish.

On his return to the capital he journeyed to the Alotepeque silver-mines in the company with the manager, and thence to Copán, Honduras, where, after spending a couple of days in examining the interesting ruins, he proceeded via Zacapa to Izabal, and there met Salvin on his way back from Belize. There they again parted, Godman returning to England, while Salvin started for Dueñas and the interior, passing through the "Altos", staying at Totonicapán and Quetzaltenango, and making expeditions to the Costa Grande, Retalhuleu, and the lagoons of the Pacific Coast to Huamuchal, close to the Mexican frontier. Salvin returned home early in 1863.

In 1865 Salvin married Caroline, daughter of J. Whitaker Maitland, of Essex, and they lived for some years in South Kensington, which became for a time the headquarters of the Godman and Salvin museum. Although both Salvin and Godman had jointly collected ever since their undergraduate years, it was not until the material was housed at South Kensington that they really did serious work together; but from then on they spent the greater part of the week in London arranging their collections, publishing papers on them, and attending the meetings of various scientific societies of which they were members.

Salvin's fourth and last visit to Guatemala was made in company with his wife. They sailed in a Royal Mail steamer in April 1873, stopping at St. Thomas and Jamaica. Then crossing the Isthmus of Panama, they reached the city of Guatemala early in June. Proceeding thence to Dueñas, which became their headquarters for some months, Salvin occupied himself in collecting in the forest of the mountain slopes. Together they ascended the crater of the Volcán de Fuego, and a few days later that of Acatenango. Leaving Dueñas for Atitlán they made the ascent of the peak from Santa Lucía on January 17th. Subsequently they visited Mazatenango, the coffee estate of Las Nubes (Cerro Zunil), Quetzaltenango, the Lake of Atitlán, Sololá, Pantaleón, and San Gerónimo, and after a short stay at the last-named place the journey was continued to Cobán. Having revisited the capital, they left Guatemala in March 1874. Again crossing the Isthmus of Panama, they sailed for the United States and visited the museums of New York, Boston, Philadelphia and Washington, and made the acquaintance of the leading scientific people, returning to England on June 4, 1875.

In the Autumn of the same year Salvin was appointed to the curatorship of the Strickland collection of birds at Cambridge, which necessitated his residence at the University. On his giving up the house in South Kensington in 1873, it had become necessary to find quarters for their museum and library, which now occupied considerable space, and they took for this purpose a house in Tenderden Street, Hanover Square, to which they were transferred. The building being rather larger than they required, they shared it with some ornithological friends.

During his stay in Cambridge, Salvin came frequently to Tenderden Street and worked at the collections with Godman, and continued doing so until the death of his father in 1880, when he succeeded to his property at Fenhurst, Sussex, where he afterwards resided, continuing, however, his work in London as before. In the Autumn of 1878 they moved their museum and library to 10 Chandes Street, Cavendish Square, and there they remained till after Salvin's death. In 1907 the house at Chanders Street was given up and the library transferred to 45 Pont Street, S. W., while the collections still remaining in their possession were handed over to the British Museum.

Meanwhile, more specimens were obtained from specialized collectors; some of them were commented upon in previous parts of this series, for example, Sumichrast, Bilimek, Saussure, Sallé, and Boucard (Papavero and Ibáñez-Bernal, 2001). Other collectors are H. H. Smith (see below), and the following, about whom very little is known: Morrison (Sonora), Rogers (Costa Rica), Janson (Chontales, Nicaragua), Forrer (N. W. Mexico, Tres Marías Island; see Escalante, 1988 and Kellogg, 1932), Höge (who collected in all Mexican States, Tamaulipas and Yucatán excepted; see Kellogg, 1932; Selander and Vaurie, 1962; Smith and Smith, 1973), Blancaneau (British Honduras), Stoll (Antigua), Schumann (Mexico). G. C. Champion explored Central America from March 16, 1879 to March 23, 1883; a very detailed itinerary of his travels was given by Godman (1915: 46-54; the same appeared in Entomol. News 1907: 46-54). T. Belt explored Nicaragua (1868-1872); the relation of his travels appeared in 1888.

Godman and Salvin continued to receive consignments from those naturalists for several yeas without having any idea of publishing a connected account of the results, and a very large amount of material, especially amongst the birds and insects, was thus accumulated. It was not till the year 1877 that it was suggested that the 'Biologia' should be undertaken, and three years later (September 1879) the first part appeared. In the meantime, various collectors were sent by them to Guatemala and other parts of Central America.

Their method of publication was to bring out six quarto parts a year, each part to contain twelve sheets made up of several subjects with six colored plates, the plates and letterpress so numbered and paged that parts might ultimately be broken up and bound together in their respective volumes when completed. In this way it was possible to keep several subjects in progress at once, and the plan answered well. They were, however, unable to adhere to the original scheme of completing the work in 60 parts, owing to the ever-increasing amount of material received from their collectors, an amount so great that 215 parts of zoology alone have been required, the dates of issue extending over a period of 36 years.

On arrival in England, the various consignments were opened, every specimen labeled with its exact locality, and the name of the collector attached. The animals were then sorted and handed over to specialists to be worked out.

In the Autumn of 1887, having been ordered abroad for the benefit of his health, Godman decided to visit Mexico, as he found himself deficient in material from that country than from farther south. Crossing the Atlantic to New York, he took the train to Mexico City, then a six days journey, entering the Mexican Republic at El Paso (3700 ft). The early part of the journey was passed during the night, but next morning it was evident that a considerably higher elevation had been attained, and on reaching Zacatecas (8000 ft), the aspect of the country was very desolate and unpromising for natural history purposes, and continued much the same for some distance, but improved a little near the capital. After spending a few days in Mexico City in making the necessary preparations, he was joined by W. B. Richardson, an American bird-collector, and with him started for the Atlantic coast. The first part of the journey, still on the high plateau, was through fields of 'agave'. In about six hours they reached Esperanza, in the state of Puebla, at the eastern edge of the plateau; there the train entered the wonderful gorge by which it descended to Orizaba, Córdoba, Atoyac and Veracruz. The scenery at once changed, the vegetation becoming luxuriant on entering the region of the rainfall.

At Orizaba they spent a few days collecting, and Godman was there joined by Mr. and Mrs. H. H. Smith, who went with him as far as Atoyac, where they remained for some time before crossing the western side of Mexico. Leaving the Smiths at Atoyac, Richardson and Godman continued their journey to Veracruz. The land gradually sloped down to the Atlantic and forming a savanna or plain of sandy ground, sparsely covered with grass and shrubs. After spending a few days collecting, chiefly to the north of the town, they took the mule tram to Jalapa, which being on higher ground reaps the benefit of the rainfall and produces far more luxuriant vegetation. At this place he engaged Mateo Trujillo, a half-breed Indian, who accompanied him during the greater part of the time he was in Mexico and proved a very skillful collector. They made an excursion to Misantla and Papantla, on the low ground near the coast at the foot of the mountain range, which proved to be very good collecting ground and added considerably to the insects. On leaving Misantla they returned to Jalapa and over to the Cofre de Perote to Esperanza, and thence by train to Mexico City. From the capital, Godman made two expeditions, the first in company with Mr. Flohr to the pretty town of Cuernavaca, and thence to the caves of Cacahuamilpa, where he hoped to have found some blind insects. The second and also interesting expedition was to Morelia and lake Pátzcuaro.

On returning to the capital, Godman next visited Yucatán, crossing the Gulf of Campeche from Veracruz to Progreso by steamer, thence to Mérida by train, where the railway then ended. His first object was to visit the naturalist Dr. Gaumer (Gorge Franklin Gaumer; see Barnhart, 1965; Bartlett, 1832; Ewan and Ewan, 1981; Godman, 1915; Hemsley, 1887; Knobloch, 1983; Rzedowski and Rzedowski, 1989; Smith and Smith, 1973), who accompanied him to the ruins of Ticul and Uxmal, a distance from Mérida of about forty miles, which journey was performed on horseback. Leaving Yucatán he went back to Mexico City, where he was joined by Mr. and Mrs. Elwes, and together they went again to Jalapa, thence, riding across the county of Córdoba, a journey of three days, and obtaining magnificent views of the Volcano of Orizaba, with its snow-clad peak. They continued their journey to Puebla and Mexico City and thence to Amecameca at the foot of the volcanoes Iztaccihuatl and Popocatépetl; the latter was ascended as far as the pine belt, where Godman found many interesting insects. They left Mexico in the spring of 1888, having been absent from home about five months and returned to England via New York.

For several years after Godman's return from Mexico, Salvin and Godman continued diligently to work out the material, and the ever-increasing amount sent over by their collectors. Salvin's failing health finally obliged him to relax his efforts, and though he still came to London, he was unable to take the same active part in the work and the difficulty of concentrating his attention on any one subject became increasingly great. He died suddenly at Hawksfold, Fernhurst, Sussex, on June 1st, 1898, leaving Godman alone to complete the 'Biologia'. At the time of Salvin's death, 141 parts of zoology (completing 13 volumes), the whole of botany (5 volumes) and nine parts of archeology had been issued; since then 74 parts (142-215) of zoology, completing 39 more volumes and 8 parts of archeology were required to bring those subjects to a conclusion. Godman took up his pen again, and with G. C. Champion finished several parts.

In 1906, the collections studied to that epoch were handed over to the British Museum of Natural History, and included:

From 1906 onwards, the remaining collections have been handed over to the British Museum as soon as the enumeration of the species was completed; that of the Coleoptera was finished in 1911. Their own general collections of the butterflies probably included nearly 100,000 specimens, and the beetles alone from Mexico and Central America perhaps double that number. Besides these, a considerable number of mammals, reptiles, fish, etc., of which no account was kept, was presented to the British Museum (Godman, 1915:1-12).

The Diptera portion of the 'Biologia Centrali-Americana' appeared in 3 volumes and one supplement (to Vol. I). In volume I, published from 1886-1887, Baron Osten Sacken (see Part 2) alone contributed 24 families; in the supplement, contributions were made by Williston (see Part 3), Aldrich (see Part 4) and Wheeler and Melander (see Part 5). In this first volume and its supplement, 997 species are enumerated, 330 of which are described as new. The six colored plates illustrate 120 species. Volume II (1888-1900) was entirely written by Wulp (see Part 6) and deals with the calyptrates. Almost all the specimens were collected by H. H. Smith. The volume was left incomplete after the death of the author in 1899, and the acalyptrates and the Aschiza were not published. Pages 429-489 (Hippoboscidae and supplement) were published after Wulp's death, although the new species of Calyptratae had already been described by him in the 'Tijdschrift voor Entomologie' for 1892. 1905 species were named by the author, of which 585 were treated as new. The 13 colored plates figure 287 species. Volume III treats the Aschiza, and was written by Williston (see Part 7). Pages 1-89 were published from 1891 to 1892; pages 93-127 and the Index for the three volumes were published in 1903. 325 species are listed, 67 of which are described as new. The two colored plates show 29 species (Godman, 1915: 77-78).

Selender and Vaurie (1962) published an excellent gazetteer for the 'Biologia' localities.

To finish this part, we present biographical data about the famous collector H. H. Smith.

Herbert Huntingdon Smith was born in Manlius, New York, on January 21, 1851. He studied at Cornell University from 1868 to 1872. In 1870, while still a student, he came for the first time to Brazil, in the Morgan Expedition. The objective of the expedition was to secure "a large quantity of specimens of all departments of nature" (Hartt, 1874), but was mainly geological, the director of the expedition, which was financed by a certain Mr. Morgan, of Aurora, New York, was Prof. Charles Frederick Hartt, a well known geologist; as associates came Prof. A. N. Prentiss, botanist; several students also came to receive a background in natural history: W. S. Barnard, C. J. Powers, P. P. Stanton, P. M. Johnson and D. B. Wilmot. Two other students, H. H. Smith and Orville A. Derby were to become famous, one in entomology and the other in Brazilian geology. T. B. Comstock came to study geology and to be the expedition's photographer. H. Kendall was the director's secretary.

In 1874, Smith returned to Brazil in order to collect and study the Amazonian fauna. He spent 2 years in the neighborhood of Santarém, in the State of Pará, and later spent one year exploring the northern tributaries of the Amazon River, as well as the river Tapajós. Afterwards he stayed four months in Rio de Janeiro.

Back in the United States, he was commissioned by Scribner's Magazine to write a series of articles about Brazil. For this purpose he undertook two more travels to that country, studying the industries, the political and social conditions, and investigating the problem of the periodical droughts of the state of Ceará. In one of those trips he was accompanied by J. Wells Champney, employed to illustrate his articles. One of the results of those trips was the publication of 'Brazil, the Amazons and the Coast' (1879).

Smith came with his wife again to Brazil, staying from 1881 to 1886. In May 1881 they spent some months in Belém (Pará), 10 days in the state of Pernambuco and 6 months in Rio de Janeiro, where they were encouraged in their collecting efforts by the Emperor, D. Pedro II. From Rio, by ship, they visited the ports of Santos in São Paulo, Paranaguá in Paraná, Florianópolis in Santa Catarina and then São José do Norte and Rio Grande in Rio Grande do Sul. Proceeding overland via Pelotas, Porto Alegre, Vimão, Caí, Jacuí, São João do Montenegro, they returned to Porto Alegre, crossed the Rio São Gonçalo, and went once more to Pelotas. Visiting other localities, they went back to Porto Alegre, Rio Grande, whence they embarked for Montevideo and then to Buenos Aires. Ascending the Rio Paraná, they visited Rosario and Corrientes in Argentina, and, proceeding up the Rio Paraguay, touched Humaitá, Asunción, and Concepción in Paraguay, reaching the village of Corumbpa, in Mato Grosso, Brazil. Navigating the rivers São Lourenço and Cuiabá, they reached the town of Cuiabá and finally Chapada dos Guimarães. Smith and his wife remained in Chapada fom 1882 to 1886, leaving only on September 6, for the United States.

Chapada has remained, since that time, one of the most famous type-localities of Brazil.

During his trips, Smith wrote a series of articles about his results and observations in the several regions in which he was traveling for one of the Rio newspapers - The 'Gazeta de Notícias'. These articles were translated into Portuguese by Capistrano de Abreu. The first was published on July 21, 1886, and the last on October 20, 1887. Later on, the articles were united into a small book ('Do Rio de Janeiro a Cuyabá, notas de um naturalista', 1922).

The collections obtained during that trip were partly acquired by F. D. Godman (and are now in the British Museum), and also by W. J. Holland, who subsequently bought the greater part of the Lepidoptera, and finally by the Carnegie Museum, which has obtained the greatest portion of all the insects, some 30,000 species in a total of 300,000 specimens. A few specimens are also in the American Museum of Natural History, New York, being mostly types described from Chapada by Williston.

In 1889, Smith worked in Mexico, collecting for F. D. Godman. These insects were to be used for the 'Biologia Centrali-Americana'.

From 1889 to 1895 he was employed by the West Indian Commission of the Royal Society, to collect in Trinidad, St. Vincent, as well as in the Windward Islands.

He was then appointed curator of the Carnegie Museum.

From 1898 to 1902, he collected in Colombia for the American Museum of Natural History (New York). The collections were made during 3 and a half years, from March 1898 to September 1901. Smith's comments about Colombia were published by Allen (1904: 408-414).

On his return to the United States, Smith resumed the curatorship of the Carnegie Museum, but later on moved to Wetumpka, Alabama, to collect molluscs. In 1910 he was appointed curator of the Alabama Museum, remaining in that position for almost a decade. He died on March 1919, in Tuscaloosa, Alabama, struck by a train.

2. THE SPECIES DESCRIBED BY OSTEN SACKEN

Karl Robert Romanovitch, Baron von den Osten Sacken, commonly known as C. R. Osten Sacken (Fig. 1), was born in St. Petersburg on August 21, 1828. He began at the early age of eleven to take an interest in entomology. It was during a temporary residence with his mother in Baden-Baden (1838-39) that he met Joseph Nikolaievitch Schatiloff, who gave him his first instructions in collecting Coleoptera.

Later on, in St. Petersburg, where he received his education and entered (in 1849) into the service of the Imperial Foreign Office, he made collections in all orders of insects, except Lepidoptera.

In 1856, he was appointed Secretary of the Russian Legation in Washington and started for his destination in the first day of April of that year. During his journey, which lasted two months, he made the acquaintance of the principal entomologists and zoologists in the cities he visited. At Königsberg, Prussia, he met Dr. H. A. Hagen, and formed an acquaintance which ripened later into a lifelong friendship and became of great importance for American dipterology. Some of the German entomologists, e. g., Klug and Ruthe (Berlin), Kiesenwetter (Dresden), Schiner, Brauer, Kolenati (Vienna), C. A. Dohrn (Stettin), he had already met during an earlier journey in 1852-53. In Berlin he had a long and interesting interview with Alexander von Humboldt in his house, but the conversation had little to do with entomology. Although eighty-seven years old at that time, and much bent by age, Humboldt was remarkably active, both physically and mentally.

In the course of his further journey, Osten Sacken visited Winnertz at Crefeld, Baron de Selys Longchamp, Candèze and other Belgium, and Wulp and Snellen van Vollenhoven in Holland. In London he made (and in part renewed) acquaintances with the principal entomologists, some of whom he remembered having met during a visit to England in 1852 (Westwood, Stainton, Francis Walker, Adam White, etc.). In the beginning of June he embarked at Liverpool on the steamer 'Arabia' and landed in New York after a passage of thirteen days.

Osten Sacken had corresponded with Herman Loew, the great German dipterologist, as early as 1850 or 1851, when he was still living in St. Petersburg. The tone of Loew's letters not having been encouraging, the correspondence was not continued. In 1856, Loew heard from Hagen of Osten Sacken's appointment as Secretary of the Legation in Washington, and suddenly displayed the greatest eagerness to renew their correspondence. He wrote Osten Sacken (Meseritz, April 11, 1856) a most urgent letter, expressing the hope that Osten Sacken would send him American Diptera, and complaining of his isolation, principally caused by his quarrel with C. A. Dohrn, President of the Stettin Entomological Society, who, as Loew contended, had him 'systematically cut off from all the sources of supply of material for work, which he formerly received through the medium of the Society'. Loew, on that occasion, sent Osten Sacken his recently published paper on Bombyliidae and concluded his letter with a characteristic flourish: 'It is a pleasure for me to think that, during the probably tedious Atlantic passage, or perhaps even on American soil, you will cast a glance on the lines of my composition, and recall my request that you should be for me a Count von Hoffmannsegg, while, in truth, I am not immodest enough to compare myself with Master Meigen'.

Osten Sacken's first task upon arriving in Washington was to compile a 'Catalogue of all previously described species of the Diptera of North America'. It was accepted for publication by the Smithsonian Institution and appeared in 1858.

During the winter of 1857-1858 he visited Cuba, where he spent 5 weeks, and returned by way of New Orleans, Montgomery (Ala.), Savannah and Florida. Although the season was not the best for collecting, he brought home many specimens, especially from Florida. In Havana he made the acquaintance of Prof. Felipe Poey.

More than two years passed after Loew's letter, during which Osten Sacken heard nothing from him although he had written him several times, and had sent him a first consignment of Diptera, as well as a copy of the Catalogue of North American Diptera, which he had published. The explanation of this mystery came in a letter, dated from Meseritz, October 1, 1858. Loew, probably in consequence of some vague association in his mind between the United States and the Declaration of Independence, had directed his letters to the Russian Legation in Philadelphia, without having noticed that Osten Sacken's letters were always addressed from Washington. After a long interval the letters were returned to him by the Post Office, and he had the mortification of sending them back to Osten Sacken with a doleful explanation.

Finally they came to the following agreement: Osten Sacken promised to send to Loew as much material as he could, on the condition, however, that he should consider the collection thus gradually accumulating in his hands not as his property, but as a trust. Osten Sacken's purpose was by this means to form a collection of North American Diptera containing the type-specimens described by Loew, as well as specimens determined by him from earlier authors, and, as the case might be, an abundant supply of as yet undescribed undetermined specimens. Such a collection, Osten Sacken conceived, would sooner or later be brought back to the United States to form a solid foundation for the further study of the American fauna. This scheme enabled him to receive without stint the numerous contributions in collections and specimens which were most generously put at his disposal by different collectors during his long residence in the United States.

This scheme came to a successful conclusion, principally in consequence of the generous intervention of Louis Agassiz. In 1877 this collection contained about 1350 species described by Loew, 330 species described by earlier authors and a large number of undescribed species, forming a total of about 3 000 species, which came back to the United States and was safely housed in the Museum of Comparative Zoology in Cambridge, Mass. At the same time, Loew received from the Museum a liberal remuneration for his work on the collection.

In consequence of his arrangement with Loew, Osten Sacken's principal efforts after 1856 consisted in procuring him materials to describe and in translating and editing his manuscripts. It required some abnegation on Osten Sacken's part to impose himself as a laborious (and comparatively subordinate) middle-man, occupied as he otherwise was with his official and social duties.

From that arrangement resulted Loew's three volumes 'Monographs of North American Diptera' (1862, 1864, 1873).

In 1871, Osten Sacken resigned his post of Consul General of Russia in New York and remained part of the following two years in Europe. In September 1873, he returned to the United States and spent the intervals between this year and 1875 principally working on the Diptera of the Museum of Comparative Zoology, where he had deposited his collections during his absence, and in preparing materials for the projected new edition of his Catalogue of North American Diptera. Between December 1875 and September 1876, he made a journey to California, the Sierra Nevada and the Rocky Mountains, whence he brought back considerable collections. A portion of the collection of Californian Diptera was worked up by him in his 'Western Diptera' (1877), after which publication he bade farewell (and this time for good) to the United States, and sailed in June for Europe.

One of the first duties he had to fulfill, after his return to Europe, was to go to Guben, the residence of Loew, and to secure the shipment to the United States of the large collection of North American Diptera which for the last twenty years had been accumulating in his hands: an arduous and risky business for him to undertake, but one which was nevertheless successfully accomplished. The whole collection arrived safely in Boston (in the autumn of 1877) and was deposited in the Museum of Comparative Zoology. With this transfer, and the almost simultaneous publication of the second edition of his Catalogue of North American Diptera (1878), the principal object of his entomological labor in the United States was fulfilled.

3. THE SPECIES DESCRIBED BY SAMUEL WENDELL WILLISTON

Samuel Wendell Williston (Fig. 2) was born in Boston on July 10, 1852, and was therefore a little past 66 years old when he died in Chicago on August 30, 1918. At the time of his death and for some years he was Professor of Paleontology and Director of the Walker Museum of the University of Chicago.

His father was a blacksmith, uneducated, but of native ability, who moved with his family to Manhattan, Kansas, in 1857. Here young Williston's boyhood was spent and in due time he entered the Agricultural College in his home town graduating from it in 1872. But his college study was interrupted, for he ran away from home at 18 and went to work as a railroad laborer, from which humble position he rose before he was 20 to be a transit man at a handsome salary for that time. However, he suffered greatly from malaria and had to resign and go back home. After recuperating he finished his college study. Railroad engineering went flat in the panic of 1873 and he begun to study medicine, 'reading' in the office of a local doctor. In the summers of 1874 and 1875 he assisted Professor B. F. Mudge on fossil-collecting expeditions in western Kansas, the work being done for Prof. Marsh of Yale University. He spent the winter of 1875-76 in the medical school of the University of Iowa and was invited to come to Yale to see Marsh in the spring; this resulted in a contract to work for Marsh for three years at $40.00 a month and in almost continuous employment with him for nine years, until 1885. He managed to finish his medical course and get his M. D. at Yale in 1880. But by this time his scientific bent was strongly developed and it soon appeared that his work lay in following it rather than in the practice of medicine. He specialized in paleontology and received his Ph. D. under Marsh in 1885. His genius for anatomy led to an appointment as demonstrator in Yale Medical School the following year, and, after a short apprenticeship, to full professorship in human anatomy in 1887 -a striking recognition of his ability.

After three years in this position, he accepted a call to the University of Kansas in 1890, as professor of historical geology and paleontology. Twelve years of his prime were spent in this institution, years crowded with productive labors. He helped organize the medical department of the University and took on the deanship of it along with his other work; this almost broke his vigorous health and he had to slacken his pace - perhaps never quite again regaining it.

The consciousness that he was working beyond his strength had something to do with his going to the University of Chicago in 1902, as professor of paleontology. Here he was able to concentrate on a single speciality, officially at least, as he left medicine behind and entomology also. In this place he spent the last 14 years of his life, beginning under some unexpected handicaps and gradually working up to full recognition and honor.

In the outline just given, entomology is hardly hinted at, for the reason that Williston never held an official entomological position. But he found time to do much valuable work as a pioneer in dipterology. His employer would not allow him to publish in paleontology and he sought a field outside where he could be free to work and publish: this he found in the Diptera. His interest in the flies became serious about 1878. At this time Osten Sacken (see Part 2) had returned to Europe and there was not a single American student of the Order, except Edward Burgess, the Boston yacht designer, who published only one small paper. So Williston was virtually alone on the continent. In the absence of guidance, he plowed his way by main strength through descriptions of species until here and there he made an identification, which served as anchor points for a new offensive. He had few definitions of genera, so he had to work backward from the species. After a year or two of this tedious and time-wasting effort he came upon Schiner's ' Fauna Austriaca ', in which the Austrian families, genera and species of Diptera as known up to 1862-4 are analytically arranged and succinctly described. To his immense relief and satisfaction, he now found that all his American flies could be traced to their families and most of them to their proper genera, in this fine work. He was so impressed by the saving of time that his own later publications show the effect of this early experience on every page; everywhere he has the beginner in mind and is clearing the way for him.

In a few years he began publishing tentative papers analyzing the American families and genera of the flies. These he extended and enlarged in a pamphlet in 1888 and again in a bound volume in 1896; and in 1908 he published a third edition, still more complete, with 1000 figures, of which 800 were made with his own hand, his well-known ' Manual of North American Diptera '. From necessity he published it at his own expense; it was eight years before the receipts from sales covered the cost of printing, but happily he lived to see this consummation.

His deep interest in genera and his wide acquaintance with them, together with his universally recognized taxonomic ability, made him the peer of Osten Saken, Brauer and others, in the period 1890-1900, as a world authority in Diptera.

The types of Williston's new species are much scattered. His Syrphidae were acquired by the U. S. National Museum, the rest of his earlier collections by the University of Kansas. His 'Biologia' material and that from St. Vincent went to London (British Museum). The American Museum of Natural History, New York, obtained his latter collections, including some duplicates of type-series from St. Vincent and Mexico.

Williston did not believe in designating a single type-specimen; hence in some cases his types of the same species are in two museums. He had no collection of Diptera in his last years, although he still retained his fine library in the Order.

In his last few years Williston published two volumes on fossil reptiles, his greatest speciality, and his last winter he was working on a handbook on Reptilia, which was probably near completion when he was compelled to abandon it.

His last years were full of honors. He was a delegate to the International Zoological Congress at Monaco; Yale University gave him an honorary Dr. Sc.; he was chosen to the limited membership of the National Academy of Science, and the Entomological Society of America made him an Honorary Fellow, one of seven out of its membership of 600.

He was married to Annie I. Hathaway, of New Haven, who survived him with three daughters and a son (Aldrich, 1918; Shor, 1971).

4. THE SPECIES DESCRIBED BY ALDRICH

John Merton Aldrich (Fig. 3) was born at Rochester, Olmster Co., Minnesota, on 28 January 1866, where he spent his childhood. In 1881, at the age of 15, his family moved to eastern South Dakota, near the Minnesota state border. He had a very brief high school career in 1884 and 1885, and later attended the State Agricultural College at Brookings, South Dakota, where he worked his own way through school. It was a new school in another country, and began on a very small scale. However, most of the students through were working their way and eager to learn, while the faculty was composed of friendly and helpful people. Aldrich received in three years of this kind of atmosphere an intellectual impetus which is not always imparted in the largest universities. Aldrich did not receive any important body of facts to carry away. His progress through the institution was accelerated by the desire of the President to have a graduating class in 1888, as a result of which he received his degree in three years. Entomology first came within his ken in the last term of college, when a course was given by Prof. I. H. Orcutt, a medical doctor who had been put on the faculty and given a large field in biology. The worthy doctor had never studied entomology himself, but he was wise enough to turn the students loose with the insects, and Aldrich made a considerable collection and enjoyed the course immensely, but without the least thought that he might continue the subject, still less find his life work in it.

After graduating, still at sea in regard to his next move, Aldrich, like a number of the other students, decided to canvass for a book to get a little ready money. Three days of this was enough to convince him that he was not made to be a book agent, and he went back to his father's farm to assist in the harvest. A few days later, while picking up wheat, the idea crossed his mind that Professor Orcutt, who had become entomologist of the newly established Agricultural Experiment Station in addition to his teaching, duties, really needed an assistant, and that an opening here might lead to an attractive field of activity. So he wrote to Doctor Orcutt, who consulted the President and wrote back that young Aldrich should study entomology through the winter, and in the spring they would see what could be done.

With this much encouragement the young man taught a term of school to get a little money and in late fall made his way to the University of Minnesota to take up entomology again. This university had then about 500 students, ranking well in size among the western institutions. President Cyrus Northrup, after the manner of the time, interviewed all the new students personally; he said they had no courses in entomology, but out at the Experiment Station at St. Anthony Park they had a very able entomologist, Otto Lugger, who would perhaps give a student private instructions during the winter. So Aldrich went out to St. Anthony Park armed with a letter from the President, and was readily accepted as a student by Lugger. Arrangements were made to eat at the new School of Agriculture nearby, and sleeping accommodations were found in a cool room used by laborers in summer. Lugger originally was a German coleopterist and had a fine collection well mounted; he had been employed by Riley in Missouri, and after some years had been in the Division of Entomology staff in Washington for a short time before coming to Minnesota a year or two before 1888. The winter's work leaned rather heavily on Leconte and Horn's " Classification of the Coleoptera of North America ", but the student could not fail to absorb some of the enthusiasm of the teacher, who was a born naturalist.

Where to go to study entomology in the fall of 1889 was one of the first questions that arose, and it was decided in favor of the Michigan Agricultural College; there was very little choice at that time, especially as the young student had not heard of Cornell University except in very vague terms. In November he started for Lansing, Mich., and spent the winter with a group of ten young men, who, under Prof. A. J. Cook, were doing what was then believed to be advanced work in entomology. Prof. Cook was an excellent teacher and a keen practical man of affairs, with tremendous energy. He advised young Aldrich to select a single order as a specialty, and to proceed at once to get together a library and a collection; he also suggested the Diptera as a large order in which there were but two workers (Williston and Coquillett) at that time in the country. The advice was accepted, and the library and collection duly begun, in the spring of 1890. Williston sent him his reprints, as did Coquillett and Osten Sacken, and he began buying at an alarming rate out of his small salary.

Returning to South Dakota for the year's work, Aldrich collected as many Diptera as possible, and arranged in the fall with Professor Hagen to spend the following winter at the Museum of Comparative Zoology at Harvard in a study of the Loew-Osten Sacken collection of Diptera, then the only one of any importance in the United States. In November he started east with this objective in view, first stopping in Ames, Iowa, to become acquainted with Osborn and Gillette. He accompanied both of the entomologists to Champaign, Illinois, to attend a meeting of the recently organized Association of Economic Entomologists. Professor Osborn shared his sleeping-car berth en route with the impecunious student, a characteristic act of kindness never forgotten.

Arriving at Harvard University, he was informed by the registrar, Frank Bolles, that Professor Hagen had suffered a stroke with paralysis, and his department had been closed, making it impossible for any one to study the collections. This was a severe blow, as it was hard to arrange any other plan for the winter without far exceeding the available funds of the student. In explaining his situation to the sympathetic registrar, Aldrich happened to allude to his graduation from the South Dakota Agricultural College; this had a remarkable effect, for Harvard University at that time was very ambitious do develop a strong graduate department and any sort of a degree meant a great deal in a student. So Mr. Bolles began planing to secure from Alexander Agassiz some concession which would permit Aldrich to remain. Following the directions of Bolles, he went to Agassiz's door expecting to see him, but was kept waiting outside while a secretary went in and explained his broken plans. After a time she came back and opened the door sufficiently to say that Mr. Agassiz could do nothing about the matter. Mr. Bolles later interviewed Agassiz himself with no results, and a letter of explanation from Aldrich to Agassiz, suggested by Bolles, brought out a printed postal card denying the request.

Forced to abandon his winter's plans, Aldrich started for Washington to see the collections there, but on the way stopped at Brown University to see Professor Packard, who was most friendly and hospitable, and took the young entomologist home to dinner, after which they spent the evening in the library, and Packard showed materials for future publications, which he was preparing. It was the first glimpse of real science and made a profound impression on the westerner.

Arriving in Washington early one morning in late November, Aldrich waited for the opening of business and pawned his watch for $5.00, after which he ate breakfast and shortly made his way to the Division of Entomology. Doctor Howard took him in charge, suggested a place to stay and arranged for his work in the National Museum, where the collection of insects was. The main part of the collection of Diptera was in the Syrphidae, where Williston's types were deposited. With these and such other material as had been accumulated, Aldrich spent three profitable weeks. A meeting of the Entomological Society of America occurred in this period, which he attended on the invitation of Doctor Howard. It was in a private house, and the small room was soon so full of tobacco smoke that at the conclusion the visitor was obliged to seek fresh air, without sharing in the social hour which was then an outstanding feature. His money exhausted, Aldrich returned home and spent the remainder of the winter classifying his flies with the help of the library he had accumulated.

The following winter was spent at home, as his collections and library had then assumed enough importance to justify all the time he could spend upon them.

In the summer of 1892 he had his first real collecting trip, a small appropriation having been secured for a trip to the Black Hills during some three or four weeks. In the Hills he joined a party from the University of Nebraska, under the management of Professor Bruner.

Conditions in the college had become disturbed, owing to factional strife; Professor Orcutt had become involved as an opponent of the President. In November several removals from the faculty took place, and among those to go were Orcutt and Aldrich. It did not take a young dipterist of those days long to decide that the proper course lay in joining Williston in the University of Kansas; so about New Year's he arrived at Lawrence, where Williston received him with open arms and he spent the rest of the year adding a little other work to his main study of Diptera. It was in the last of June, after the close of the college year, that he was appointed Professor of Biology in the University of Idaho (1897).

Aldrich then married Ellen Row, of Brookings, South Dakota, and moved to Moscow, Idaho. The loss of his wife and infant son four years later caused him to plunge most deeply in to his dipterological work, and he began his card catalogue of the literature on Diptera, a project to which he contributed almost daily until his last illness. By 1905, when this catalogue had reached publication size and was about ready for submission to the Smithsonian Institution, Aldrich married Della Smith, of Moscow, Idaho, and receiving sabbatical leave of absence from Idaho went to Stanford University for a year. His Ph. D. degree was awarded by Stanford in 1906. Fortunately Aldrich had moved his collection and library of Diptera to his father's house, because during his absence the University of Idaho burned to the ground. Idaho's loss proved to be the nation's gain. Dr. Howard immediately appointed Aldrich to the Bureau of Entomology. The death of Frederick Knab in 1918 made it necessary to transfer Aldrich to the National Museum, where he was appointed Custodian of Diptera and Associate Curator.

Aldrich contributed many papers to the knowledge of the Diptera, and especially the chapter on Dolichopodidae to Williston's Manual (1908) and to the Biologia Centrali-Americana (1901). He also published on the Dolichopodidae and Phoridae for the " Diptera of St. Vincent " (1896). His Catalogue of North American Diptera (1905) will remain forever as one of the monuments in dipterology (Aldrich, 1930).

Aldrich died on 27 May 1934 (Melander, 1934).

5. THE SPECIES DESCRIBED BY WHEELER AND MELANDER

The Empididae portion of the Biologia Centrali-Americana (1901) was studied by William Morton Wheeler and Axel Leonard Melander (18 new species described from Mexico).

William Morton Wheeler was born in Milwaukee, Wisconsin, March 19, 1865. He became known as a specialist in embryology, morphology and anatomy of insects, and as a foremost authority on ants and other social insects. The first 19 years of his life were spent in his native city, where he graduated from the German-American Normal College in 1884. On February 7 of that year he entered Ward's Establishment of Natural History, Rochester, N. Y., where he remained until he returned to Milwaukee, June 24, 1885, to become a teacher of German and physiology in the High School under Geo. W. Peckham, with whom he later collaborated on a paper on spiders and helped on wasps. During this period he spent much of his time studying embryology until 1890. On September 19, 1887, he was appointed custodian of the Milwaukee Public Museum where he remained until August 29, 1890, when he received a fellowship at Clark University under C. O. Withman on October first of that year. Here he also acted as an assistant in zoology and received his Ph. D. degree in 1892. All this time he was instructor in embryology at the University of Chicago, where he remained until 1895, becoming assistant professor in 1897. During 1893-1894 he studied abroad at Würzburg and Liège and was also the occupant of the Smithsonian table at the Naples Zoological Station. According to his own works, his association with Peckham, Whitman and William Patton made him a morphologist. Therefore much of his early work in embryology and morphology is in the general field of zoology. He was professor of zoology at the University of Texas, 1899-1903; curator of invertebrate zoology, American Museum of Natural History, 1903-1908; honorary fellow and research associate since that time; professor of economic entomology, Bussey Institute, 1908-1926; and professor of entomology since 1926, becoming the dean of the Bussey Institute 1908-1930. He was elected fellow of the American Academy of Arts and Science, American Association for the Advancement of Sciences, Washington Academy of Science, New York Academy of Sciences, Texas Academy of Sciences; member of the American Morphological Society, American Society of Naturalists, American Society of Zoologists (President of the East Branch, 1908), National Academy of Sciences, American Philosophical Society of America; Entomological Society of America (President, 1908) and the Ecological Society of America; corresponding member of the Philadelphia Academy of Science, Société Biologique de France, and honorary member of the Société Entomologique de France.

Axel Leonard Melander was born in Chicago in 1878 and graduated from the University of Texas in 1901. From 1904 to 1926 he was head of the Department of Zoology at Washington State College, and after that, head of the Department of Biology at the College of the City of New York.

6. THE SPECIES DESCRIBED BY FREDERIK MAURITS VAN DER WULP

Frederik Maurits van der Wulp (Fig. 4) was born in The Hague, on 13 December 1818 and died in the same city on 27 November 1899. His entire career was spent at the Dutch Audit Office, where he entered on 1 September 1843, passing successively to second clerk (1 June 1846), head clerk (1 January 1848), assistant officer (1 April 1854), officer (1 July 1869), head officer (1 January 1879), referendary (head of the special branch at the Audit Office, 1 January 1880), and retired on April 1893. He was nominated Knight of the Order of the Orange-Nassau. On 26 May 1848 he married Jeanne Louise Cornelia Brederhuysen, by whom he had four children (3 sons and 1 daughter).

Wulp's wife died on 11 August 1895. From the death of his wife to his death on 27 November 1899 he lived with his only daughter (Snellen, 1900).

From 1870 to 1892 Wulp published many papers on Neotropical Diptera, based especially on the collections found in Amsterdam and Leiden. Many of his specimens were sent from Argentina by Hendrik Weyenbergh. He cooperated in the Biologia Centrali-Americana with the Muscoidea and Pupipara portions (1891b, 1895-1900, 1903), as well as some families of Acalyptrates. Most of Wulp's types are in the Zoölogisch Museum, Amsterdam (including many syntypes of the Muscoidea described in the Biologia Centrali-Americana) and some are at the Rijksmuseum van Natuurlijke Historie, Leiden. The greatest part of the syntypes described in the Biologia Centrali-Americana went to the British Museum (Natural History), London.
