Abdomen beneath sparsely, coarsely, irregularly fossulate-punctate, sparsely 

 clothed with rather short, recumbent, white hairs, with more or less distinct 

 lateral callosities, intervals finely granulose ; last visible sternite broadly, deeply, 

 arcuately emarginate at apex, with a rather distinct, serrate, submarginal ridge, 

 lateral margins coarsely serrate ; eighth tergite coarsely, sparsely punctate, lower 

 margin rounded or slightly emarginate at apex, upper margin angularly pro- 

 duced at apex. Prosternum coarsely, densely, irregularly punctate, sparsely 

 clothed with long, recumbent, whitish hairs ; anterior margin broadly rounded, 

 but without a distinct median lobe. Anterior femur with a short, rather acute 

 tooth, which is coarsely dentate on outer margin. Anterior tibia strongly arcuate, 

 with a rather acute tooth near apex ; middle tibia slightly arcuate ; posterior tibia 

 straight. 



Length 7.5 mm., width 3 mm. 



Female. — Differing from the male in having the front of the head uniformly 

 reddish cupreous, the last visible sternite shallowly emarginate at apex, the 

 eighth tergite densely, coarsely punctate, and broadly rounded at apex, the 

 middle tibia straight, and the anterior tibia unarmed near apex. 



Redescribed from a pair of paratypes donated to the United States 

 National Museum by E. C. Van Dyke. 



Type locality. — St. George, Utah; type in the California Academy 

 of Sciences. 



DISTRIBUTION 



From material examined: 



Utah : St. George, June 28, 1935 : Mt. Carmel, near Zlon Canyon, May 30, 1935 



(E. C. Van Dyke). 

 Nevada: Esmeralda County, June 27, 1907 (F. W. Nunenmacher). 



Host. — The larval habits are not known, but Dr. Van Dyke collected 

 his large type series of adults on juniper (Juniperus sp.), which is 

 probably the host for this species. 



Very little variation was observed in the small number of speci- 

 mens examined, and Van Dyke states that the color is quite stable in 

 the large type series. Some of the specimens have the pronotum 

 widest at the apical third, with the sides converging posteriorly, 

 whereas in others the sides are parallel and slightly sinuate at the 

 middle and more or less constricted at the base. The median and 

 lateral depressions on the pronotum are sometimes obsolete. The 

 length is from 7 to 8.5 mm. 



There is some doubt about this being a valid species. The genitalia, 

 tooth on anterior tibia of male, and sculpture are similar to those of 

 speculifer, and the writer has been unable to find any characters for 

 separating it from that species except color, which according to 

 Van Dyke is constant in a large series; so it is retained as a valid 

 species until more material is available for study and its habits and 

 distribution are better known.
