Of rather slender form, compressed, faintly 

 pubescent, brownish testaceous, heavily 

 flecked especially on tegniina with dark or 

 blackish fuscous ; the pronotum typically 

 with a large central spot above and a patch 

 at the upper limit of the lateral lobes on the 

 prozona ; the tegniina heavily flecked almost 

 uniformly throughout but especially on basal 

 half with blackish fuscous, deeper in tint in 

 southern examples, there being but faint 

 traces of transverse fasciation. Head testa- 

 ceous, all the carinae punctate with black, the 

 fastigium of vertex shallow but with raised 

 margins and a feeble median carina ; antennae 

 dull testaceous banded with fuscous. Prono- 

 tum posteriorly rectangulate, the margin of 

 the process punctate or interrupted with 

 black. Tegmina broad; liind wings subfal- 

 cate, pale sulphureous basally, this color 

 often extending furtlier along the rays, 

 crossed just beyond the middle by an unequal, 

 sometiines broken, more or less cloudv, fus- 

 cous band, sending a taenia nearly half way 

 to the base in the humeral field, the apical por- 

 tion of the wing hyaline with fuscous veins, 

 the costal stigma infumate; form of the 

 wings precisely as in C. undulatus, but the 

 venation differing in that the upper branch 

 of the first subjacent radial unites at birth, as 

 an oblique cross-vein, with the first superja- 

 cent radial, in which point it differs from all 

 the other species. Hind femora cinereo-tes- 

 taceous, thrice fasciate with blackish fuscous ;
