Imago. — Wings semidiaphanous ; rather broad. Male. Foreu'/ii^/ subtriangular, 



rounded exteriorly ; costal vein extending to two-thirds the margin ; cell extending 



to half length of the wing; subcostal vein four branched, first branch emitted at 



about one-third before end of the cell, second at a short distance before the end 



and terminating at the apex, third and fourth at nearly half distance beyond end of 



the cell ; upper discocellular veinlet absent ; the upper radial being emitted beyond 



end of the cell, middle discocellular extending obliquely inward, concave, long, 



lower discocellular short, straight, aud inwardly oblique ; lower radial so positioned 



as to appear like a fourth median branch ; median branches equidistant apart ; 



submediau vein slightly recurved, aud with a lower basal short branch extending to 



the posterior margin. Hindiving broad, ovate ; costal margin much lobed at the 



base, exterior margin very convex, abdominal margin long, curved inwardly, not 



channelled ; precostal vein stout and straight, truncate at the tip ; costal vein much 



arched from the base, and with a weakly-developed interno-basal veinlet forming 



a basal costal cell; discoidal cell extending to about half the wing; first subcostal 



branch emitted at one-fourth before end of the cell ; upper discocellular veinlet 



longest, radial from the angle ; median veinlets equidistant apart, lower emitted at 



one-third before end of the cell; submedian vein rather short, straight. Bodi/
