with remainder of club. Palpi well separated, thickly scaled, 

 forming two square projections in front of the face ; third joint 

 hardlv visible. Fore wing : male with a costal fold ; cell more than 

 two-thirds length of costa ; discocellulars very oblique, middle one 

 straight, lower strongly arched and mucli the longer ; vein 3 just 

 before end of cell ; vein 2 about twice as far from 3 as from base of 

 wing. Hind wing much elongated ; vein 3 immediately before end 

 of cell ; vein 5 wanting. Hind tibiae with two pairs of spurs. 



This genus is readily recognized by the unique character of the 

 lower discocellular of the fore wing.
