and Mr. J. C. Crawford, assistant curator of the division, pre- 

 sented their valuable private collections of Hymenoptera. Mr. 

 Viereck's collection contains about 2,400 specimens, mostly bees, 

 including types of more than 50 species and paratypes of some 50 

 more. Mr. Crawford's collection consists of about 2,700 specimens, 

 with many types and paratypes. The Bureau of Entomology trans- 

 mitted large collections as in past years. Those reported as of most 

 importance are 2,383 Diptera from Florida and South Carolina, 

 collected by Mr. C. H. T. Townsend; 1,038 miscellaneous insects 

 from Santa Catalina Island, California ; 1,000 insects from Alabama, 

 obtained by Mr. H. H. Smith; and 400 mosquitoes from Dublin, New 

 Hampshire, collected by Mr. A. Busck. From Lord Walsingham 

 and Mr.' F. D. Godman there were received, partly as a gift and 

 .partly in exchange, about GOO micro-lepidoptera from Central 

 America, chiefly cotyj^es of species described in the Biologici Gen- 

 trali-Americmia. Four hundred and twenty Coleoj)tera from the 

 same general region were obtained from Mr. Godman in exchange. 

 About 5,000 Venezuelan insects were purchased, and the Washing- 

 ton Biologists' Field Club added to its previous donations about 

 1,000 insects from l^lummer's Island, Maryland. 



The entire collection of Orthoptera was transferred to drawers 

 adapted to the new standard racks, and some progress was made in 

 the same direction with the Lepidoptera, Coleoptera, and Hymenop- 

 tera. The investigations of Doctor Dyar and Mr. Knab on mosqui- 

 toes, mentioned in last year's report, were continued and brought 

 nearly to completion. Loans of insects to specialists for investiga- 

 tion numbered 20 and comprised 4,389 specimens. The largest lot, 

 containing 1,500 tropical American ants, was sent to Dr. William M. 

 Wheeler, of the Bussey Institution, Boston. Prof. A. L. Melander, 

 of Pullman, Washington, obtained 326 Diptera of the family Borbor- 

 idse. Orthoptera of the family Forficulida^, to the number of 328 

 specimens, were lent to Mr. IMalcom Burr, of Eastr}^, England, and 

 305 Hemiptera to A. L. IMontandon, of Bucharest, Roumania. ]\Ir. 

 G. C. Champion, of London, received 298 beetles for use in connec- 

 tion with the Biologia Centrali- Americana^ and Prof. H. T. Fernald, 

 of Amherst, Massachusetts, 350 Sphegida? and Ophionina^ for study. 



Mollusks. — The heirs of the late Chief Engineer Herschel INIain, 

 U. S. Navy, presented a valuable collection of about 1,500 marine 

 shells, which had been obtained in different parts of the world. A 

 very interesting lot of land shells from Cuba and another from the 

 Isthmus of Darien, including new species, were donated b}^ Mr. A. E. 

 Heighway. Among the purchases which comjjrise some of the most 

 important accessions should be mentioned a series of recently de- 

 scribed shells of Japan, a series of rare land and fresh-water shells 

 from Tonkin, China, and land shells from the mountains of 

 Venezuela.
