and but little longer than the basal, 4th nearly as long 

 as the 2nd and pointed at the extremity. Labium small, 

 very slightly emarginate in front, clothed with a few 

 long hairs. Labial palpi 3-jointed, basal very small, 

 2nd much longer, 3rd a little longer than the 2nd, 

 thicker at the base than at the apex. Prothorax trans- 

 verse, with the anterior angles produced into sharp 

 points, the posterior angles slightly reflexed. Scutellum 

 transverse. Elytra depressed, subparallel, and covering 

 the abdomen, humeral angles obtuse, slightly produced 

 and reflexed. Legs unarmed ; male with posterior tarsi 

 4-jointed, the other tarsi 5-jointed ; claws with a small 

 obtuse tooth in the middle. 



This genus will come into the subfamily Cucujince, 

 as defined by Erichson, and must be placed near 

 Lcsmophloeus.
