Wings: The wings are broad at the base, rather 

 pointed apically, the marginal and all the posterior 

 cells widely open, the anal cell closed with a long stalk. 

 The alula is large but not arising from the base vein. 

 The upper end vein of the discal cell is almost elimi- 

 nated, the middle end vein of the second basal cell com- 

 pletely eliminated, the small crossvein enters the middle 

 of the discal cell. 



Abdomen: The abdomen is short, blunt and robust, 

 nearly as wide as the thorax or quite as wide; it is 

 pollinose with rather dense but quite fine erect pile. 

 Bristles absent. Sides of the first tergite not covered 



Genus Bromleyus E. Hardy 



Bromleyus E. Hardy, Canadian Ent., vol. 76, p. 226, 1944. Type 

 of genus : Bromleyus flavidoraus E. Hardy, 1944, by origi- 

 nal designation. 



Curious flies and perhaps phylogeronts. Robust and 

 about the size of a small bumblebee, with high, strongly 

 arched mesonotum which is very densely covered with 

 long, slightly appressed brownish, brassy pile over its 

 whole surface except for a narrow, bare space above the 

 base of the wing. Scutellum largely covered on the 

 convex disc with similar, long, dense, erect pile. Abdo-

by the metasternum. In the males 8 tergites present, 

 7 well developed, the fourth to the seventh of nearly 

 equal length, the integument soft. Male terminalia 

 large and conspicuous, not rotate, the epandrium long, 

 collarlike, extended backward and with downward 

 curved flaps, its apex truncate. 



Distribution : Nearctic : Orrhodops americanus Cur- 

 ran (1930). 



I have before me an undescribed species from Mexico. 

 Probably Damalis occidentalis Williston, from Mexico, 

 belongs here and possibly also Damalis fdivisus Walker, 

 from Brazil. 



men drooping and rather short pilose, tending to be 

 bare of pile along the base of the tergites. Wing 

 strongly tinged with brown, uniformly covered with 

 dense villi, the marginal cell widely open, the fourth 

 posterior cell greatly narrowed and the anal cell closed 

 and stalked. The upper anterior intercalary vein is 

 about three-fourths as long as the medial cross vein, 

 the third vein forks beyond the end of the discal cell 

 and the anterior cross vein enters the discal cell barely 

 before the middle. Posterior cross vein wanting. All 

 the femora are stout throughout their length, and all 

 the tibiae and basitarsi conspicuously swollen and
