Pronotum strongly convex, slightly gibbose in front of scuttelum. 

 widest near middle ; sides broadly rounded, coarsely tuberculate along

 densely, coarsely granulose. the granules on basal half strongly ele- 

 vated and distinctly separated from one another, apical half with 

 numerous broad, strongly elevated teeth, which are longer, acute at 

 apices, and separated at bases from one another along anterior margin. 



Elytra at base slightly wider than pronotum near middle; surface 

 with longitudinal rows of coarse punctures on disk, the rows confused 

 at sides and sometimes along sutural margins, punctures about as 

 wide as intervals, rather densely clothed at sides and on apical declivity 

 with long, erect, yellowish hairs, intervals on basal half of disk with 

 distinct rows of elevated, conical granules, without a round depression 

 at apices, but from which arises a short, erect hair; apical declivity 

 with moderately elevated, irregularly distributed granules. 



Abdomen beneath sparsely, shallowly punctate, sparsely clothed 

 with long, recumbent, yellowish hairs.

Type locality. — Seli^man. Ariz. Type in the Casey Collection in 

 the United States National Museum. 



This species was described from a single specimen. The depressions 

 on the type are obscured by dirt, and if it were cleaned, the entire sur- 

 face would be polished.
