Interspace between eyes as broad as (male) or rather broader than 

 (female) the first antenna! joint; frontal costa moderate, equal, flat 

 above, sulcate at, below, and to some extent a short distance above, 

 the ocellus. Pronotum expanding a very little posteriorly, mostly on 

 the posterior half, the front and hind margins truncate, the latter some- 

 times almost imperceptibly emarginate in the middle, especially in the 

 male, the lateral carinae wholly wanting; the whole pronotum is equally 

 subrugoso-punctate throughout, unless it be that the disk is coarser 

 than the deflected lobes; meso- and metanota, and the basal segments 

 of the abdomen similarly but more obscurely punctured. The general 

 color is a greenish yellow more or less tinged with brown, brighter in the 

 male than in the female, and marked with blackish fuscous; the darker 

 markings consist, principally, of a dorsal stripe, which either extends 

 over the pronotum as a broad equal band, often fainter in the middle, 

 with a triangular extension on the head, and sometimes a narrowing 

 infnscatioii on the meso- and metanota (male), or forms an obovate 

 patch along the middle of the anterior lobe of the prothorax, with the 

 same triangular extension on the head, and reappears sometimes on the 

 meso and metathorax, and always on the abdominal joints, as a series 

 of obliquely-descending, triangular, lateral patches, separated from one 

 another by a yellowish median line (female) ; also of a broad lateral band, 

 which extends from behind the eye backward, either to the hinder edge 

 of the prothorax, its upper margin straight, its lower arcuate (male), or 

 across the prozona only, occasionally in an obscure manner across the 

 metazona also, both margins arcuate (female); beyond this the lateral 

 band extends over the remainder of the thorax and over the abdomen, 

 often broken into spots on the latter, and always enlivened on the for- 

 mer by an oblique yellowish line, which crosses it on the metathoracic 

 episterna. The face partakes of the color of the under surface, as do the 

 bases of the antennae; beyond, the antennae become slightly rufous; 

 just behind its narrowest point the vertex has a transverse blackish 

 line, Hind femora greenish yellow, the lower portion of their outer 

 face more or less embrowned, deepening frequently into black, which 

 occasionally covers the whole; hind tibiae pale green, the spines black 

 tipped. Subgenital plate of male twice as broad as long, tumid, the 

 upper edge a little and angularly produced in the middle; supraanal
