 This genns must be referred to the Ilydriomenhiae ; the costal vein of the hind- 

 wings anastomoses with the subcostal for nearly the whole length of the cell ; the 

 discocellular is oblique ; the ueuration of the forcwing is quite normal, the areule 

 being double. The forehead is large and tumid ; and the j)alpi are upcurved in 

 front of face.
