Distribution. — From material examined : 



California: Los Gatos (Hubbard and Schwarz). Fresno, May 3 (E. A. 

 Schwarz). Cordelia, Solano County, June 9, 1933 (E. C. Zimmerman). 



Host. — Nothing has been recorded on the habits of this species, but 

 Zimmerman collected the adults on Quercus agrifolia. 



Horn described this species from a single female and the species 

 was unknown to Lesne (1899) when he published his revision of the 

 genus.

Male. — Elongate, cylindrical, uniformly dark reddish brown, the 

 palpi, antennae, and tarsi brownish yellow; dorsal surface of body 

 unevenly clothed with moderately long, recumbent, whitish hairs, 

 which form more or less distinct pubescent spots. 



Head much narrower than pronotum, densely, finely granulose, finely 

 tuberculose, the tubercles narrowly separated ; clypeus flat, indistinctly 

 punctate, anterior angles rectangular ; clypeal suture distinct ; labrum 

 indistinctly punctate, glabrous, densely ciliate with long, yellowish- 

 white hairs in front. Antenna 10-segmented ; third to seventh segments 

 round or slightly transverse. 



Pronotum quadrate, strongly convex, widest near middle, strongly 

 deflexed on apical half, truncate or broadly emarginate in front, with- 

 out unciform processes in front or depressions in front of scutellum ; 

 sides broadly rounded; posterior angles rectangular, surface with a 

 narrow, longitudinal, median carina or smooth space on basal half, 

 finely, rather densely irregularly tuberculose, the tubercles becoming 

 rasplike toward apical angles. 



Elytra at base slightly wider than pronotum at middle, truncate at 

 base, without longitudinal costae; sides parallel, conjointly broadly, 

 arcuately emarginate at apices, with a long acute spine on each side of 

 emargination ; surface coarsely, deeply, confluently punctate, the in- 

 tervals slightly rugose. 



Body beneath finely, densely punctate, sparsely clothed with short, 

 recumbent, inconspicuous hairs. 



Female. — Differs from the male in having the apex of each elytron 

 obtusely angulate and without a long, acute spine, and the last abdomi- 

 nal sternite most densely clothed with long, yellow hairs. 



Length 6-9 mm. ; width 2-2.6 mm. 



Type locality. — Alabama and Kentucky ; types in the LeConte Col- 

 lection in the Museum of Comparative Zoology, Cambridge, Mass.
