clypeus is rather feebly emarginate, the posterior carina of th€ head 

 of the male is produced into a shont, broad plate, from the middle of 

 which arises a narrow horn, the lower carina is absent; the pro- 

 thorax is rather convex and declivous in front without projections. 

 The female has the head with the usual two carinse and the prothorax 

 is less convex than in the male and in fully developed specimens there 

 is at middle a short, broad projection.

I have a few specimens from Prescott, Ariz., received from Mr. 

 George Franck, which are referable to this Mexican species. The 

 color is black, opaque, surface sparsely clothed with short, stout, 

 fuscous hairs ; clypeus at apex reflexed and rather deeply emarginate 

 at middle. Prothorax strongly but not densely punctate, subasperate 

 near apex. The elytra have the stri?e feebly impressed and punctate, 

 the intervals with two more or less regular rows of punctures. The 

 males have the upper carina of the head feeble the lower is absent. 

 The prothorax in the male is lobed at middle, the lobe short and 

 broad, rotundate-truncate and slightly reflexed at apex and emarginate 

 at middle. The anterior tibi?e of the male are elongate and slightly 

 curved at apex. Length 4.5-5 mm.

This species occurs in the pine region of Long Island and New 

 Jersey and extends as far south as Florida. 



Dull brownish-black, elytra with a variable number of pale spots, 

 which are rarely absent. The clypeus is emarginate at apex; the head 

 has the vertex bitubcrculate in both sexes, the lower carina is more 

 feeble in the male than in the female; the prothorax is unmodified 

 and alike in male and female.
