Imaco.—Male. Wings short. Forewing rather narrow, subtriangular; costa 
arched, apex obtusely convex; exterior margin short, almost erect, very slightly 
convex, even, posterior angle obtusely convex ; posterior margin long ; costal vein 
thick; first subcostal veinlet emitted before end of the cell, second at nearly one- 
third beyond the cell; the cell broad ; discocellulars outwardly-oblique, upper angled 
close to the subcostal and concave below; lower discocellular long and_ slightly 
outwardly-recurved ; upper radial from angle close to subcostal, lower radial from 
above the middle; median veinlets at equal distances apart ; submedian vein re- 
curved from the base. Hindwing short, very broad, triangularly-ovate ; anterior 
margin broadly lobate at the base and nearly straight outwardly; apex obtuse ; 
exterior margin very conyexly-produced hindward from the middle; abdominal 
margin long; costal vein with a long inner spur near the base, terminating near the 
apex; first subcostal veinlet emitted at about one-third before end of the cell area, 
the radial (the base of which is homologous to an upper discocellular) starting from 
below the second subcostal at one-third from its base ; lower discocellular completely 
atrophied (as seen in the desquamated wing under the microscope), thus leaving the 
cell quite open; the cell area moderately broad; the two upper median veinlets 
emitted from the lower end of the cell area ; submedian vein with a raised fold along 
its outer edge and scantily fringed with fine long hairs, the fold terminating beyond 
the middle in a small longitudinal scabrous glandular patch of scales overlaid by a 
tuft of long erect hairs. Body rather long, abdomen slender, not tufted ; eyes naked; 
palpi much compressed, curved and extending to level of the vertex, thickly clothed 
with appressed hairy-scales beneath and with longer hairs above, the tip distinct, 
slender, acute at the tip; legs long; antennz long, distinctly articulated, with a 
lengthened gradually slender club and acute tip.
