This remarkable species lias recently been thoroughly described 

 for the male sex by Rehn.^^'' It represents a distinctive and aber- 

 rant 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 colora- 

 tion 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 ochraceous- 

 tawny, 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 addi- 

 tion, each have a few microscopic dots of dark brown along the 

 caudal margin. 



Chorisoneura panamae new species (Plate VI, figures 9 and 10.) 



The present species is a member of what we term the Pellucida 



'»2 The ventral femoral margins, in our o])inion, are supplied, characteristically, with 

 a few hairs, rather than "supplied with a few weak, short spines." The male supra- 

 anal plate is about one-third as long as its basal width, with apex broadly truncate and 

 subbilobate.
