widest at the eyes which are near the middle, obliquely narrowed

becoming moniliform; fifth, sixth and seventh larger; beyond 
this the joints become large, forming a very gradual but stout 
club, of which the joints except the last are barely wider 
than long. Pronotum slightly projecting at its humeral angles, 
twice as long as the mesonotum at the sides; the mesonotum 
separated by a deep grooved line, no longer than the portion of
