North American Nitidulidse 
117 
Described from thirteen specimens collected by Barber 
and Schwartz on June 8 at Las Vegas Hot Springs, New 
Mexico. The male holotype, allotype, and 6 paratypes in 
the U.S.N.M., one pair of paratypes in the Mus. Comp. Zo- 
61. and one para type each in the collections of H. C. Fall 
and the writer. Also one paratype from the Pinal Mts., 
Arizona and one paratype from the Sierra Ancha Mts., Ari- 
zona in the collection of H. C. Fall. 
Pocadius. 5, P. basalis Schaeffer (topotype); 6, P. helvolus Er.; 7, 
P. niger n. sp. (paratype); 8, P. ferrugineus L.; 9, P. fulvipennis Er. 
This is the species listed by Fall and Cockerell in their 
New Mexican list as fulvipennis. In the profile of the pro- 
sternum, and characters of the female genitalia this spe- 
cies is intermediate between helvolus and basalis. It dif- 
fers from both of them by being less oval, the prothorax 
black, more convex, with narrower margin, and more ob- 
tuse hind angles. The pubescence is longer and the puncta- 
tion of the elytra, at least in the New Mexican specimens, 
more regular and distinct.
