100 Mr. B. P. Uvarov on 
basal half widened towards apex and its apex distinctly- 
broader than the base of the following joint, so that the 
antennz seem to be obtusely bi-serrate. 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 fastigium of vertex by an arched 
emargination. Lateral ocelli placed close to the eyes, very 
small. Fastigium of the vertex a little longer than its 
basal width, rotundato-triangular ; its surface lies on 2 
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 coarsely and densely punctured,

forming thick convex lateral margins. Vertex between the 
eyes convex, with a well-developed median carinula and two 
irregular low lateral carinule; all these carinule extend 
into the occiput, but do not reach the pronotum. Eyes 
strongly oblique, elongato-oval, with the apex pointed, one 
and a half times as long as broad and more than twice as 
long as the infraocular space. Pronotum compressed later- 
ally; its disc distinctly convex in the prozona and more 
flattened in the metazona, 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 equal to one-third of its fore part ; 
the hind part of prozona almost twice as long as its middle
