There is a European species which must closely resemble this 

 one in structure of the palpi, latipalpis Stein, but the lower calyp- 

 ter projects beyond the upper in the latter. It is known onh^ in 

 the male sex. 



The species was already known to me when the present collec- 

 tion was received. 



Fannia sp.? 



There is a female specimen in collection, from Cloudcroft, New 

 Mexico, May 23, 1902, which bears a strong resemblance to that 

 of polychaeta Stein, but I prefer to have it without specific 

 identification until I can examine more specimens. 



Subfamily Anthomyiinae 



The genera of this subfamily are very poorly defined, there 

 being no published keys or descriptions wliich serve to separate 

 accurately the genera Phorbia, Pegomyia, Hylemyia, Chortophila, 

 Erevioyyiyia, and some others. The arbitrary characters used by 

 the older authors have resulted in many cases, in a distinctly un- 

 natural grouping and a thorough revision of generic concepts is 

 essential. 



I have used the generic names Pegomyia and Hylemyia in this 

 paper, but hope soon to publish an accurate synopsis of generic 

 characters for the group, the key herein presented being drawn 

 up to cover only the genera in this paper.
