This remarkable species lias recently been thoroughly described for the male sex by Rehn.^^'' It represents a distinctive and aberrant unit of the genus, which we would term the Parishi Group.
The female sex closely resembles the male, differing in having the tegmina slightly shorter, the interocular space very slightly wider, very slightly greater than that between the antennal sockets, the supra-anal plate more distinctly and sharply bilobate distad and subgenital plate of considerable lateral length, with a decided medio-longitudinal cleft distad.
All of the specimens here recorded are of a more intensive coloration than the two originally described Brazilian examples, the head with face blackish chestnut brown, shading to a paler brown on the occiput. In the two palest examples the head is ochraceoustawny, tinged with chestnut brown only above the clypeal suture.
In the immature condition, the pair of lateral, poorly defined dark pronotal bars are continued on themesonotum and metanotum, and as a narrow suffusion margining the entire dorsal surface of the abdomen; the four proximal dorsal abdominal segments, in addition, each have a few microscopic dots of dark brown along the caudal margin.
