Chalia, Moore, Annals of Nat. Hist. 1877, p. 345. 



Wings quite transparent, naked ; abdominal border fringed with, fine hairs : 

 forewing short, broad, arched at the base, ronnded at apex and at posterior angle ; 

 cell broad, upper pai't longest; subcostal vein five-branched, the branches very 

 short, first and second arising before end of the cell, fourth and fifth, at equal 

 distances from louver side of third and terminating below the apex; disco cellular s 

 insvardly oblique, lower bent inward at half its length; discoidal veinlet emitted from 

 angle of lower discocellular and anastomosing with subcostal near end of the cell ; 

 one radial emitted from lower end of upper discocellular; median vein four-branched, 

 the two lower from before end of the cell, curved, third at end of the cell, fourtli 

 short and emitted at half the length of th.e latter ; submedian vein recurved to two- 

 tliirds its length, thence straight to posterior angle, throwing off an upper branch : 

 hindwing short, broad, rounded at apex and anal angle; cell broad; subcostal vein 

 arched at the base, extending to apex ; upper discocellular straight and erect, lower 

 bent inward at its middle and emitting a discoidal veinlet which extends to base of 

 the cell ; median vein three-branched ; submedian and internal vein straight ; body 

 slender, densely pilose, the hairs standing out in lateral tufts ; abdomen extending 

 beyond hindwings. Antennae deeply bipectinated ; legs slender.

 slight fringe ; cilia composed of spatulate scales : f orewing elongated, costa arched 

 at the base, apex rounded, exterior margin oblique and slightly convex, posterior 

 margin short ; costal vein extending to middle of margin ; subcostal vein four- 

 branched, first branch arising at half length of the cell, second and third at slight 

 angles near its end ; discocellulars short, slightly oblique ; radial starting from their 

 middle ; cell broad ; two discoidal veinlets extending from middle of discocellulars 

 within the cell, which are joined together beyond half its length and then extend to
