2 $ ignotae. 



This genus is nearly allied to Plagiopleura, differing from it in having the eyes 

 somewhat ovate ; the metasternal lobes not separated by a triangular notch ; and the 

 median vein of the elytra not straight and not reaching the tip. Chloroscirtus might be 

 placed next Parableta, the median vein of the elytra being directed, as in that genus, 

 to the hind margin of these organs. 



In its general facies Chloroscirtus resembles Scudderia, but differs from that genus in 

 having the vertex not contiguous to the forehead. The males may be distinguished 

 from those of Scudderia by the existence of long styli on the infra-genital plate. In 

 both sexes the elytra are more attenuate towards the end, and the tip therefore is 

 more narrowly rounded. 



Obs. — When the styli are broken off, the males might be mistaken for the same sex 

 of Scudderia.
