than half as wide near the neck as at the base, convex, 
equally vaulted, basal median fovea small, no additional basal 
punctures. /ytra as long as the prothorax and half the 
head; the width across the high prominent acutely rounded 
shoulders is four-fifths of this measure, and across the tip one- 
fifth greater. Disk convex, discal lines very deep at the base, 
abbreviated near the middle. Sutural lines straight, deep, 
especially near the base, leaving an interrupted transverse 
basal elevation. Sides from the shoulders to the posterior 
fourth almost imperceptibly arcuate. Addominal segments 
subequal, the first dorsal depressed along the base, border 
narrow. Legs long, femora clavate, tibiae angular length- 
wise, tarsus thicker at the articulation of the second and third 
joints, tapering towards base and claws. 4 anterior tro- 
chanters provided with a long slender spine at base, inter- 
mediate coxe with a straight thinner spine.

ffead triangular, the lateral angles behind the eyes trun- 
cate, parallel, acutely rounded to the nearly straight very 
slightly sinuate base, arcuate towards the eyes, anterior to 
the parallel tempora, thence abruptly narrowed and _ pro- 
duced into a parallel-sided frontal protuberance, which has at 
the tip a conspicuous elongate impression. Vertex with two 
rounded fovez in a transverse line one-third from the base, 
mutually separated by a distance as great as that separating 
them from the parallel tempora. Eyes small, at about the 
middle of the sides of the head, scarcely visible from above.
