atro})liied, running nearly parallel with and immediately above 

 the median ; third median nervule much bent at its origin. 

 Posterior wings sub-ovate, costal nervure long, sub-costal ter- 

 minating only in two nervules, upper discocellular nervule 

 wanting, discoidal nervure distinct and simple throughout its 

 whole course to the outer margin, with a slight bend at its 

 junction with the short disco -cellular which connects it with 

 the median nervule : bristle in the male simple, retained by a 

 corneous retinaculum arising from the posterior side of the 

 sub-costal nervure, compound in the female, retained by a 

 bunch of scales arising from the anterior side of the median 

 nervure. 



Anterior legs short, tibiae with a strong sharp spine about 

 the middle, the first joint of the tarsi about the same length as 

 the tibisB, the four remaining ones equal in length to the first : 

 second pair with the tibiae about two-thirds as long as the 

 tarsi, bi-spinose at the extremity, first joint of the tarsi nearly 

 equal to all the rest : posterior legs with the tibiae about two- 

 thirds the length of the tarsi, bispinose at the apex and fur- 

 nished also with two spines beyond the middle, first joint of 

 the tarsi longer than the rest combined. Claws of all the 

 feet simple, tarsi spiny. 



Abdomen cylindrical, arched in the male, tufted at its ex- 

 tremity, in the female tapering to a point. 



There seems to be a slight difference in the structure of the 

 antennae in this genus, in the first species the club is rounder 

 and less mucronate than in the two following ones, it seems 

 also destitute of the tuft of scales at the point.

Anterior wungs of the male brown, clouded with gre}"^ and 

 fuscous-brown, a dark cloud near the base, another at the end 

 of the discoidal cell followed by a white dot, the nervures
