 yellow, impunctate; the face thickly covered with long,

 The front in the middle and vertex broadly black ; the 

 black on the vertex continued half way down the back, 

 becoming narrowed towards the apex. Tips of the 

 mandibles black. Thorax shining, impunctate, thickly 

 covered with long, soft hair, which is darker on the meso- 

 notum. The middle lobe of the mesonotum is raised ; 

 the middle at the apex is quite flat ; the scutellum raised ; 

 at the base transverse and|bordered by a straight furrow. 

 The apex of the propleurae is triangularly raised ; the 

 oblique furrow on the base of the mesopleurse is con-
