8 THE LEPIDOPTERA OF CEYLON. 



discocellular very inwardly oblique, radial from below the middle ; the middle median 

 at one-third and lower at one-half befoi'e end of the cell ; submedian much recurved, 

 arched upward and extending close to lower median towards the end, emitting a 

 straight short basal branch near the base : hindwing with nearly straight costa, apex 

 very convex, exterior margin even, slightly concave in the middle and angular at end 

 of submedian vein, abdominal margin short ; cell broad, extending half the wing ; 

 costal vein extending to apex ; subcostal with a short spur joined to costal at one- 

 third from the base ; two subcostal branches at one-third beyond end of the cell ; 

 discocellular outwardly oblique, slightly convex, radial from one-third above its lower 

 end ; middle median at one-sixth and lower at two-fifths before end of the cell ; 

 submedian and internal veins widely apart, internal recurved and terminating at anal 

 angle. Body moderately stout, smooth, fusiform, male with short lateral anal tuft ; 

 thorax extending half beyond base of wings ; head short ; palpi compactly adpressed ; 

 antennge short, serrate-ciliate ; proboscis not visible. 



CYPA FERRTJGINEA (Plate 79, Fig. 3). 



Cijpa ferruginea, Walker, Catal. Lep. Het. Brit. Mus. xxxi. p. 42 (1864) ; Boisd. Spec. Gen. Lap. 

 Het. p. 53 ; Butler, Trans. Zool. Soc. 1867, p. 554. 



Ferruginous : forewing with two or three very indistinct transverse darker 

 waved fasciae, and three similar discal fasciae, the inner discal being broadest and the 

 two outer sinuous, the points of the latter paler ; the fasciae in the male more distinct 

 and with paler interspaces ; the outer margin of the wing dusky ferruginous ; a small 

 dusky black spot at lower end of the cell : hindwing palest along costal border ; cilia 

 ferruginous-yellow. Abdomen with slightly darker ferruginous dorsal segmental 

 bands. 



Expanse, c? 2, ? 21 inches. 



Genus MARUMBA. 



Triptogon (part), Butler, Trans. Zool. Soc. 1876, p. 586.* 



Forewing long ; costa much arched towards the apex ; exterior margin oblique, 

 scalloped ; posterior margin concave towards the end ; first subcostal emitted at 

 one-third and second at one-ninth before end of the cell, fourth from below third at 

 nearly one-half beyond the cell, fifth from immediately beyond the cell ; discocellular 

 slight, very oblique and concave, radial from below the middle ; cell extending to 

 half the wing ; middle median at one-fifth and lower at one-half before end of the 

 cell; submedian much recurved, emitting a lower inward branch at one-fifth from 

 the base : hindwing narrow ; apex convex; exterior margin slightly scalloped, and 

 angulated near apex ; cell broad, short, not extending to half the wing ; costal vein 



* The type of Triptogom, Bremer {T. dissimilis), belongs to a different group.
