a slight rim and with a middle ridge ; front flat, a little longer than 

 broad, slightly convex and with a middle ridge towards the vertex. 

 Antenna? long, linear, terminating in a long slender bristle. Prothorax 

 more than twice as broad as long, arched and vitreous in front, extend- 

 ing over part of the vertex, slightly concave behind. Mesothorax flat, 

 with three slight ridges, forming a short spine hindward. Abdomen 

 elongate conical, about half the length of the fore wing. Legs rather 

 slender ; femora and tibia? flattened, ridged ; fore femora and fore tibia? 

 dilated. Wings vitreous. Fore wings with the transverse veinlets 

 forming two upright parallel lines ; diseal areolets very long ; costal 

 areolet extremely long, with two approximate oblique veinlets at its tip. 



This genus may be distinguished from Dichoptera by the structure 

 of the legs, wherein it has some affinity to Poiocera ohliqua ; and the 

 latter should form a new genus.
