REPORT ON THE DEPARTMENT OF INSECTS IN THE U. S. NATIONAL 

 MUSEUM FOR THE YEAR ENDING JUNE 30, 188G. 



By C. V. Riley, Honorary Curator. 



Beyond the mere preservation of accessions and proper attention to 

 correspondence little original Museum work has been attempted, as 

 the curator's services are voluntary, and the only assistance furnished 

 was the temporary employment for a few months of Mr. Albert Koe- 

 bele. Much was, however, done, indirectly, through the Entomologi- 

 cal Division of the Department of Agriculture, as more or less pure 

 Museum work is consectaneous with that of said division. » 



In August, 1885, Mr. J. B. Smith, of Brooklyn, N. Y., already favor- 

 ably known by his writings on Lepidoptera and Coleoptera and by 

 his activity as a member of the Brooklyn Entomological Society, was, 

 npou my recommendation, appointed as assistant, and with this ap- 

 pointment assured I formally donated my private collections to the 

 Museum. 



THE RILEY DONATION. 



This is mentioned among the accessions as No. 16738, and as the cir- 

 cumstances connected with the donation will probably be alluded to in
