rounded obtuse-angulate, face hardly retreating, subvertical; frontal 

 costa very narrow, siibequal (female) or very slightly expanding 

 (male) dorsad of the ocellus, slightly constricted ventrad of the 

 ocellus, the margins diverging thence and becoming fainter until 

 hardly appreciable at the ch^peal suture, sulcate except in the 

 ventral fourth; eyes moderatel}^ (male) or hardly (female) prominent, 

 elongate subreniform-ovate in outline, slightly longer than (male) 

 or equal (female) to the infra-ocular portion of the genee; antennae 

 about equal to the caudal femora in length, simple, coarse, sub- 

 moniliform distad. Pronotum with its dorsal length about four- 

 fifths that of the caudal femora, the median carina elevated, cristate, 

 arcuate, produced cephalad and caudad, the height of the crest from 

 the dorsum being slightly more (male) or slightly less (female) than 

 a fourth the length of the same, the margin of the crest entire; cephalic

margin protluced rectangulate, caudal margin produced into a 

 lanceolate process in length but little less than equal to the remainder 

 of the pronotum; disk not at all flattened, sloping ventrad into the 

 vertical lateral lobes, lateral angles but slightly developed on the 

 metazona and these rounded; transverse sulci three in number, the 

 principal one the deepest, none intersecting or even ascending the 

 sides of the crest; lateral lobes with the dorsal length slightly greater 

 than the depth, cephalic margin arcuate emarginate around the side 

 of the head, ventral margin obtuse-angulate, caudal margin oblique, 

 the ventro-caudal angle rounded obtuse-angulate. Tegmina about 

 twice the length of the pronotum in the male, one and one-third times 

 the length of the same in the female, broad in both sexes, the greatest 

 width contained four and one-half (male) or two and one-third
