basal half widened towards apex and its apex distinctly 

 broader than tlie base of the following joint, so that the 

 antenna) seem to be obtnsely bi-scrrate. Head shorter, but 

 thicker, than the pronotum. Face very strongly reclinate, 

 very coarsely punctured throughout ; frontal ridge scarcely 

 impressed, gradually divergent downwards, not reaching the 

 clypeus; median ocellus very small. Fastigium of the front 

 widely separated from the tastiginm of veitex by an arched 

 emargination. Lateral ocelli ])laced close to the eyes, very 

 small. Fastigium of the vertex a little longer than its 

 basal width, rotundato-triangnlar ; its surface lies ou a 

 distinctly lower level than the vertex between the eyes, but 

 still there is no transverse sulcus separating the fastigium 

 from the rest of the vertex; the middle area of the fastigium 

 up to the apex is smooth and flat, while the sides of its 

 upper surface are very coaisely and densely punctured,

forming thick convex lateral margins. Vertex between the 

 eyes convex, with a Avell-developed niedian carinula and two 

 irregular low lateral carinulae ; all these carinulse extend 

 into the occiput, but do not reach the pronotum. Eyes 

 strongly oblique, elongato-oval, w'ith the apex pointed, one 

 and a half times as long as broad and more than twice as 

 long as the iufraocular space. Pronotum compressed later- 

 ally; its disc distinctly convex in the prozona and more 

 Hattened in the metazoua, cut by three straight transverse 

 sulci ; prozona one and a half times as long as the metazona; 

 the fore part of the prozona subequal to the metazona ; the 

 middle part of prozona ecpial to one-third of its fore part ; 

 the hind part of prozona almost twice as long as its middle
