[May, 'i8 



Van der Wulp described (loc. cit.) a Pogonoinyia aterrima 

 from northern Alexico (Ciudad Durango, 8100 feet) ; as his 

 description agrees and I have the northern species from as far 

 south as Southern Cahfornia, there is no reason to question 

 that aterrima is the same as the Idaho species. I redescribe 

 it farther on. 



Stein's other North American species was even more un- 

 fortunate, as he described the male in the same paper under 

 the name Spilogastcr >iitcjis (p. igg) : auite recentlv, more- 

 over, one of the females with Stein's label "Pogonomyia n. sp." 

 came under the eye of Mr. Malloch. and as he had the male he 

 described the species under the name Pogonoinyia flavincrvis. 

 This synonymy I made out from the type of nitens (which, 

 by the way, is from Toronto and not Massachusetts as Stein 

 gives it') ; it has been rubbed on the most accessible side of the 

 head, and consequently does not show as many bristles on the 

 epistoma as is characteristic of the genus, which doubtless ex- 

 plains the mistake. 



Generic Characters. Alpicola shows the following charac- 

 ters in both sexes, which I consider of generic importance (see 

 figure of head) : 



Entirely shining or subshining black color ; epistoma strongly 



produced and upturned, the 

 vibrissae above the lower 

 edge of the head ; bucca and 

 back of head with abimdant 

 long bushy hairs ; sides of 

 epistoma with bushy hairs, 

 some of which are directed 

 upward; para facial wide; 

 front prominent, antennae 

 short, the arista nearly 

 bare ; eyes bare ; acrostich- 

 als merely hairs except the 

 hindmost pair; calypters un- 

 equal, the hind ones rather 

 front ones ; halteres black ; 

 of abdomen bearing rather
