The species here referred does not seem tn l)elong-in this genus, Imt I 

 can find no ..thcr with which it so well agrees.- The form is compact, stout, 

 well rounded, and even. 'i1ic head is short, l)road at base, and tapers verv 

 rapidly to the very stout snout, which more nearh- resendjles that of 

 ►Strophosomus, though the antenna! scrohes pass toward the middle of the 

 eye iuid not beneath it; the head is granular, like the thorax, but the beak 

 smooth : the l)eak tapers with an arcuate upper surface, and shows no sign 

 ofaiiical eidargeinent; the eyes are not large, and are circular. The thorax 

 is profusely l)iit r; it her delicately granulate, ami its uppci- surface forms a 

 uniform arch with the not very convex elytra; it is short, and the sides of 

 file front are roundly and deeply eiiiarginate. Ehfra aliout twice as long 

 as broad, with tine, sharp, deep, delicately juuictate .stria-; interspaces tiat,
