Type in author's collection. 



The species seems to be western in its distribution. The indi- 

 viduals of one locality show the variations mentioned above to a less 

 extent than individuals of separated localities.

 as thorax, finely punctate ; vertex arcuate on posterior margin, 

 deeply excavated discally, almost glabrous, emarginate in front at 

 median line, and bulging roundly on each side of emargination. 

 Genal cones short, broad, rounded at apex, contiguous at base, 

 slightly divergent, with short pubescence. Clypeus small. Antennae 

 about twice as long as width of head. 



Thorax large, broad, strongly arched both longitudinally and

 broad at base, simple; pubescence long and dense. Female. — Genital 

 segment moderately long, stout, rather small; dorsal valve longer and 

 more acute than ventral; ventral valve stout, blunt at apex. 



Described from several males and females from: Kedwood Creek, 

 Humboldt County, California (H. S. Barber), on "White Myrtle," 

 in June; Siskiyou County, California (Koebele), on Ceanothus; North 

 Bend, British Columbia (Schwarz), on Ceanothus sanguineus; Orms-
