158 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 Josephine 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 MordeUistena unicolor 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 MordeUistena amhusta in systematic 

 arrangement.
