Diinensions. — $ Length from the vertex to the tip of the elytra, 0.65 

 inch. 



Nebraska (Scudder). 



Remark. — It is possible that Ihis is the male of that which I have 

 described as St. maculipennis from Omaha, but Mr. Scudder's description is 

 too brief to determine this witli certainty. It probably belongs in Section 2, 

 with St. maculipennis. • "

The lateral foveote at the margins of the vertex distinct. The frontal 

 costa prominent, straiglit, reaching to the clypeus ; very narrow between the 

 antennas ; the lateral carinfe of the face distinct. The antennae distinctly flat- 

 tened near the base. The elytra in both sexes somewhat longer than the 

 abdomen. 



Color. — Testaceous, often fuscous above ; the posterior femora banded 

 or fasciate ; tibiae pale, fuscous at the base, where also there is a whitish band 

 or ring. 



Dimensions. — Length, O.-'iO to 0.G2 inch. 



Pennsylvania (Burmeister). 



Remark. — I have not met with this species — at least, I have not recog- 

 nized it among the numerous collections I have examined ; in fact, Burmeis- 

 ter's description is so meager that it is doubtful whether it will ever be recog- 

 nized with satisfactory certainty ; but it evidently belongs to Stenobothrus.

Stenobothrus (in part), Fisch. 



Face almost vertical or sub-oblique. Antennae long, multiarticulate, 

 filiform for three-fourths of the distance from the base, the remaining joints 

 forming a compressed expanded mass, not so large in the female as the male, 

 terminating in a point. Ocelli slightly visible. Eyes oval, slightly promi- 

 nent. Pronotum short; its disk flat, tricarinate ; the lateral caringe sinuous, 

 curving inward or forming an entering angle near the middle ; the poste- 

 rior border rounded. Elytra and wings as long or a liltle longer than the 

 abdomen. Abdomen somewhat compressed ; sub-anal plate of the male 

 usually convex below, almost triangular. Prosternum unspined, smooth. Legs
