Black, with 2 large triangular yellowish spots at the base of the 

 abdomen; palpi dusky; mandibles at the tip, and legs, testaceous; 

 coxae, fore femora at the base, 4 posterior wholly except the tips,

When compared with the ? of C. inanitus this is very 

 distinct ; more elongate, the abdomen regularly elliptical, 

 rounded behind instead of obtuse ; the antennae are 

 •^ longer, stouter and less attenuated at the apex ; the 

 frontal fovea is smooth and shining; the wings are 

 darker and more ferruginous ; the radial areolet larger, 

 the 2d cubital more produced inwardly, the parastigma 

 and basal nervures paler, and the posterior femora
