XII. INDIAN FLIES OF THE SUBFAMILY 



RHINIINAE. 



By Charles H. T. Townsend, Ph.D., 

 Custodian of Muscoid Diptera, U.S. National Museum. 



The family Muscidae (syn. Calliphoridae) divides into two 

 subfamilies, the Muscinae and the Rhiniinae. The Muscinae are 

 numerously represented in all habitable parts of the globe ; but the 

 Rhiniinae are strictly confined to the Old World, with the sole 

 exception of Pollenia which has reached America almost certainly 

 through the agency of man. 



The material considered in this paper was submitted to me 

 for determination by the Indian Museum. The following synoptic 

 table will enable the identification of the genera of this subfamily 

 known to me, a few genera not represented in the Indian collec- 

 tion being included with their localities. In order to complete 

 this survey of the Rhiniinae, there are appended at the end of the 

 table notes on seven genera probably belonging to this subfamily 

 but not known to me in material, some of which may be found to 

 occur in the Indian region. 



Genera of Rhiniinae. 



Epistoma/?/;/;/m-like, strongly warped forward 

 Epistoma Phasia-Wka. projected downward 



rather than forward... 

 Arista plumose, ciliate both above and below 

 Arista ciiiate only above

 Arista long-plumose to tip ; frontalia of male 



pinched out by the nearly contiguous eyes, 



the parafrontalia reduced to a line
