THE INSECTS OF NEW JERSEY. 847 



Nat. Mus. Mr. Schwarz is the best Coleopterist at present living in 

 the United States. He has been good enough to look over the previous 

 list and to note errors and probable errors. In this way it has been 

 cleared of most of such species as were erroneously identified. Mr. 

 Schwarz has determined many New Jersey specimens for others as 

 well as myself, and, notably, all the "Staphylinids" credited to Mr. 

 Reinick. He has done little collecting in New Jersey, yet is sole 

 authority for the occurrence of several good species in our State. 



Thompson, J., Staten Island, N. Y. Collects "Coleoptera"; his records 

 cited by Mr. Davis or Mr. Leng. 



U. Ulke, Henry, late of Washington, D. C. With Mr. E. A. Schwarz he 

 compiled a list of "Coleoptera" in the District of Columbia, with notes 

 on the food and other habits of the species, and these notes when 

 used are credited to "U." 



Uhler, Dr. Philip R., Baltimore, Md. Our leading authority in "Hemiptera- 

 Heteroptera." The records cited are chiefly from his check list. Dr. 

 Uhler has also determined much of the material cited by other con- 

 tributors to this list. His credit is therefore greater than appears 

 from the actual number of citations made. 



U. M. = U. S. N. M. 



U. S. Ag. United States Department of Agriculture, Division of Ento- 

 mology. In this division an index is made of all the species com- 

 plained of or sent in for information, and the locality from which the 

 species was sent or complaint was made is connected with the species. 

 Dr. L. O. Howard, Entomologist to the Department, was good enough 

 to have this index looked over for records of species sent in from 

 New Jersey, and quite a number of useful notes were obtained in this 

 way. 



U S N M. United States National Museum, Washington, D. C. This col- 

 lection is now altogether the largest in the country, though exceeded 

 by individual collections in almost every order. It contains much 

 material from New Jersey from my old collection, which was sold to 

 the Museum in 1887, from the Linell collection of "Coleoptera," and 

 from the Fox collection of "Hymenoptera." There is also some 

 material from other sources, and I have looked over all the orders 

 other than "Coleoptera," "Lepidoptera" and "Diptera" for notes as 

 to localities or other data. 



Van D. Van Duzee, E. P., Buffalo, N. Y. Specialist in the "Hemipteja," 

 and chiefly in the "Homoptera." Has determined much material for 

 me and for other collectors, and has himself collected at several points 

 in the State. Without his assistance the lists in the "Homopterous" 

 families would be far less complete. 



Vk. Viereck, Henry L., Division of Entomology, U. S. Dept. Agric., and 

 previously of Philadelphia. Specializes in the "Aculeate Hymenop- 

 tera," and has collected extensively in New Jersey. Mr. Viereck has 

 done for the present edition in "Hymenoptera" what Dr. Ashmead did 

 in the last.
