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 reachesNthe 3d 

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

 LEC. Class. Col. N. America, 238. 



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

 nized by the epistorna being broadly rounded in front, not separated 

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

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

 as in Hypophlceus ; antennae 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 striae ; the prosternum is not 

 prominent behind the front coxae, which are small and rounded ; 

 middle coxae closely surrounded by the episterna, trochantin not 

 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.
