The Anthomyid Genus Pogonomyia (Dip.)-* 



By J. M. ALDRICH, U. S. Bureau of Entomology. West 

 Lafayette, Indiana. 



The genus Pogonomyia was established by Rondani in 1870 

 (Bull. Soc. Ttal., ii, 336, xxiii) for a single species, alplcola, 

 v. Inch was designated as type ; it came f rom Mont Cenis in 

 the Alps. The main characters are repeated by Van der \Vulp, 

 Biologia, Dipt., ii, 334, 1896, and by Meade, Desc. List. Br. 

 Anth., London, 1897, p. 29. I translate tlic entire description 

 from Rondani's Prodomus Dipt. Ital., vi, 37, 1877: 



"Eyes bare, almost contiguous on the front in male. Front prom- 

 inent. Oral margin, especially at the sides of the epistoma, with dense 

 erect beard. Antennae short, the second segment with rather long 

 setulae ; arista nearly bare. The hind calypter a little longer than the 

 front one. Anterior crossvein directly behind the tip of the first vein ; 

 sixth vein rather long but not reaching the margin. Front and middle 

 femora of ordinary structure, the hind ones with a row of setae below; 

 middle tibiae with setae behind and on outer side; hind tibiae some- 

 what incurved toward tip. Apex of abdomen setose but not densely 

 villous." 



Dziedzicki and Schnabl (Die Anthomyiden, 1911, 196) ad- 

 mit several rather divergent species, so that the genus in their 

 conception is difficult to define ; they recognize two subgenera, 

 Pogonomyia and Pogonomyiclla. 



Stein, in his classic work on North American Anthomyidae 

 (Berl. Ent. Zeitsch., xiii, 1897, 169, 170) mentioned two spe- 

 cies found in the N. A. collections sent him. The first, from 

 Idaho, he identified doubtfully as alpicola, a species with which 

 he was not acquainted ; the other he recognized only in two 

 females and did not describe. As I furnished the Idaho ma- 

 terial, most of it was returned to me, and I collected more 

 specimens in the West in later years. Only a couple of years 

 ago I sent some to Professor Bezzi. and he informed me that 

 they were not the European alplcola, and sent me a pair of 

 the latter to support his opinion. Later 1 found nlpicoln in 

 Colorado.
