Elytra at base slightly wider than pronotum near middle; surface 

 coarsely, densely, irregularly punctate, the punctures on disk not so 

 wide as intervals, sparsely clothed with erect, yellowish hairs, uni- 

 form in length, and as long as width of punctures on basal half of 

 disk, but much longer toward sides and on apical declivity, intervals 

 on disk smooth, without distinct granules; apical declivity coarsely,

 pinon (Phi us monophylla Torrey and Fremont) by J. E. Patterson.
