AntemifB black, covered with a pale down. Front and 

 vertex closely punctured; the vertex with a shallow, the 

 ocellar region with a wider and deeper longitudinal furrow ;

 and thick. The base of the median segment is alutaceous ; 

 the furrow on the apex does not extend much beyond the 

 middle ; it is large, wide, rounded at the top, triangular at 

 the apex ; except at the top, the apex of the segment is 

 closely transversely striated. Pleural closely and minutely
