In the Heterocera an equally good showing in the number of 

 species is made, but as the number of these vastly exceeds that of Rho- 

 palocera in no case can any faunal region be said to be thoroughly well 

 represented. The collection is tolerable rich in European forms. Of the 

 species enumerated from North America in Grote's Check List about 

 one-half are found in the collection, and when all of the material on 

 hand shall have been correctly worked up and determined the number 

 will no doubt be found to be largely increased. From Jamaica there 

 are nearly 400 species as yet undetermmed. There are fully one thou'^and 

 species of Heterocera from Equatorial Africa in the collection of which 

 only the merest fraction has been determined and no doubt many of the 

 species are as yet non-described. The Japanese fauna is represented by 

 nearly nine hundred species of Heterocera, among them the enliie col- 

 lection of the Hypenidaj, Deltoids and Pyralids of Japan made by. Henry 

 Pryer which the writer purchased in October, 1887, from his now 

 lamented friend, — fully 375 species, the majority of them as yet unde- 

 scribed, a monograph of which he now has in course of preparation. 



In addition to these considerable collections there are large numbers 

 of Heterocera from the Indo-Malayan region, derived from various 

 sources, among diem all the specimens contained in the collection of 

 the late Dr. Rossler of Stuttgart, (lermany. 



While not making a study of the Coleoptera and other Orders the 

 writer has incidentally obtained much valuable material, representing 

 them. There are over 2,000 species of the Coleoptera of Norih America 

 in the collection determined by such eminent authorities as Drs. Leconte, 

 Horn and Hamilton. To the latter especially the writer is under mani- 

 fold obligations for many kindnesses shown in the determmation of 

 species. Jamaica is represented by several hundreds of species of Co- 

 leoptera, mostly undetermined. Equatorial Africa is represented by over 

 one thousand species, of wliich not more than five per cent, are deter- 

 mined. Japan is represented by a nearly equal number of which not 

 more than fifty species are as yet correctly determined. The same re- 

 mark holds good as to the Indo-Malayan region. The European 

 Coleopterous fauna is represented by about seven hundred species mostly 

 Caj-abidce and Ceramhvcido'. The BuprcsiidcB of Austialia through a 

 recent purchase are fairly represented. 



In addition to collecting the insects the writer has found it neces- 

 sary, owing to the absence of any great public library in the City of 

 Pittsburgh, to also undertake the collection of works relating to Ento- 

 mology and has amassed during the past five years the nucleus of a con- 

 siderable collection containing the Transactions and Proceedings of al-
