Front of head s(piare ; palpi slender, but more bushy than in IleenKitopls. 

 Antennae with long, sparse branches, not ])lumose. I'ore wings rather long; 

 costa well arched ; apex not so much produced as in Hcpmatopls. Apex 

 ])()inted, outer Ci\ge less oblique than in ILematop'is. Hind wings with a 

 sliglit bend; scarcely extending as far as the end of the abdomen, which is 

 long and slender in the male. Venation: costal vein anastomosing with the 

 subcostal in the middle of the snl)costal cell, the latter situated entirely or 

 partly beyond the discal venules. Three very short, subcostal veins arc 

 thrown off to the costa. Lower discal venule very oblique. Coloration : red 

 and Ijrown, with blackish patclic.-;. 



In this genus, the Inishy palpi, square front, tliinly-l)ranclH'd antenna' 

 and high colors are distinguishing mark.s. It approaches Fidunia more sen- 

 sibly than Hcematopis.
