DESCRIPTIONS OF NEW SPECIES. 131 



nearly flat, and finely but not densely punctulate, the 4th and 8th 

 striae are shorter than the others ; the 5th and 6th unite together 

 near the end of the 4th, and their prolongation readies the 3d 

 stria near the tip of the elytra. Beneath coarsely punctured.

New York, two specimens. This genus will be readily recog- 

 nized by the epistoma being broadly rounded in front, nol separated 



from the front by a suture; the basal membrane of the labrnm 

 visible; eyes not emarginate, frontal margins very short, nearly 

 as in Hypophlceus ; antennas slender, with the 3d joint scarcely 

 longer than the 2d, and the last three joints about one-half wider 

 than the 8th. The epipleurae extend to the tip of the elytra, 

 which are entirely destitute of strias ; the prosternum is not 

 prominent behind the front coxa?, which are small and rounded ; 

 middle coxas closely surrounded by the episterna, trochantin nol 

 visible; mesosternum declivous, scarcely concave ; last two ventral 

 sutures deeply impressed ; legs moderate, tibia not dilated, spurs 

 very minute, tarsi hairy beneath, last joint as long as the others 

 united, with large claws. 



The total absence of the frontal suture is a rare character, but 

 is found in several genera of this tribe. I also observe that the 

 gula is longitudinally impressed at the middle; the mentum is 

 very small, and the last joint of the maxillary palpi slightly di- 

 lated and triangular.
