 basally and broadly rounded apically, with its disc glabrous ; man- 

 dibles elongate, somewhat slender and unideutate ; cheeks very 

 short. Antenrue of d 1 longer than the body, filiform, centrally 

 white-banded, with their apical joints discreted and subattenuate. 

 Thorax short and stout ; notauli very deeply impressed and dis-
