T58 THE CANADIAN ENTOMOLOGIST 
Linear; entirely black, covered with short, brown, sericeous 
pubescence; head large and nearly as wide as the thorax; eyes 
coarsely granulated ; thorax longer than wide, a little wider than 
the elytra, its base at middle with a diagnostic, V-shaped notch as 
wide as the scutellum; anal style moderately long, rather robust. 
Length 5 mm. 
Seven specimens: five from Josephi-ne Co., Oregon, June 8, 
and one from Plumas Co., California, June 14; all collected by 
Mr. F. W. Nunenmacher. 
The type from Josephine Co., Oregon, is placed in the writer's 
collection; paratypes are in the collection of Mr. F. W. Nunen- 
macher, to whom this species is dedicated. 
This species is nearest Mordellistena icnicolor Lee, or sericans 
Fall., but can at once be distinguished by the triangular-shaped 
notch at the base of the thorax. Some of the specimens at hand 
have a very small rudimentary ridge on the tibia and first joint of 
the hind tarsus. 
This should follow Mordellistena amhusta in systematic 
arrangement.
