Imago. — Male. Wings short. Forewing rather narrow, subtrianorular ; 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 veiulets 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 convexly-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 Mi a s?waZZ longitudinal scabrous glandular patch oi 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 ; antennas long, distinctly articulated, with a 

 lengthened gradually slender club and acute tip. 



Type. — X. Busiris.
