Foveola of the vertex in the female slightly transverse, divided by a 

 median carina, triangular in front, the margins connecting in front or 

 approaching near to each other in a right angle ; in the male somewhat 

 elongate ; the frontal costa prominent, sub-tricarinate above the ocellus, very 

 -slightly sulcate below it; face, seen from the side, slightly arcuate. Median 

 carina of the pronotum prominent, sub-cristate, entire, very slightly arcuate ; 

 front margin obtuse-angled, slightly advanced upon the occiput ; apex about 

 right-angled ; lateral carinse obsolete ; surface rugulose. Elytra and wings 

 passing the abdomen. Posterior femora passing the abdomen. Antennse in 

 the female scarcely reaching the tip of the pronotum ; proportionally longer 

 in the male. 



Color. — Dusky-brown, varying from an ashen to a dark hue. Elytra 

 rather j^aler than the head and thorax, more or less distinctly spotted 

 with brown. Wings deep-yellow at the base and on the basal half of the 

 front margin, bounded externally by a dusky-brown band beyond the middle, 

 which curves and is prolonged on the hind margin, but does not reach the 

 anal angle; a sub-marginal ray of the dark, extending two-thirds the distance 

 to the base, separates the yellow of the margin from that of the disk ; apex 

 translucent, dusky. Posterior femora black inside, with two white bands; 

 posterior tibiae dusky, with a pale ring near the base ; middle sometimes 

 bluish.
