^. Clypeus densely clothed with cinereous pubescence, advanced 

 and broadly truncate at the apex. Head and thorax rugulose, 

 the cheek produced into a short blunt spine at the base of the 

 mandibles and with a long beard of curled cinereous hairs. The 

 pubescence pale fulvous and thin on the front and the mesonotum, 

 cinereous and thick on the occiput, prothorax and median seg-

 the extreme base. Abdomen subpunctate, first segment short 

 and stouter than is usual in the genus, a strong median sulca 

 from the base not reaching the apex, and a very obscure carina 

 from the end of the sulca to the apex. Second segment with a 

 faint median carina from near the base to the apex; a similar 

 carina, scarcely visible, on the third segment. Segments 2-4 with 

 a rounded elevation on each side near the apical margin; tlie 

 second strongly, the third and fourth slightly constricted near
