convex ; costal vein extending two-thirds the margin; subcostal branches far apart, 
first branch at one-third before end of the cell, second immediately before the end, 
third and fourth (or upper radial) on a foot-stalk one-third beyond the cell; lower 
radial from upper end of the cell; discocellular veinlet deeply concave; cell more 
than half length of the wing ; middle median at one-eightli and lowei at nearly one- 
half before end of the cell; submedian vein recurved. Hindwing triangularly-oval, 
exterior margin very convex ; precostal vein short ; costal vein arched at the base;
