until he had published a revision of the Pipunculidse of the 

 United States. With the exception of this paper, his publica- 

 tions have been only on the Calyptratae. 



Finding himself compelled to give up entomology in favor 

 of his profession, Dr. Hough recently sold his collections and 

 library at a nominal price to the University of Chicago. By 

 .this event, dipterology loses a worker characterized in a marked 

 degree by energy, accuracy and individuality. His methods 

 were his own, and were direct and scientific. Their only end 

 w^as the advancement of dipterolog}^ ; hence his most extensive 

 piece of work was really done by Stein, although Hough was 

 directly responsible for its inception. In going back to the 

 European species for the foundation of his work, Hough pur- 

 sued the only possible course for the Calliphorinse, since many 

 of ours are the same ; and in every family, there is need of 

 constant watchfulness to recognize in our fauna the described 

 European species. The only correct way to identify them is 

 by comparison with carefully determined European specimens. 



Dr. Hough^ turned over with his library one unpublished 

 paper, a lengthy one on the Sarcophagidse, which it is hoped 

 will be published by the University of Chicago. His published 

 papers are the following :

 siders one of his principal contributions to entomology.
