30. Genus Ctenoptilum. 



Ctenoptilum, de Niceville, Journ. Bomb. Nat. Hist. Soc. vol. v. 

 p. 220 (1890). Type, vasava, Moore. 



Antenna? : club rather robust, gradually thickened, recurved, finely 

 pointed. Palpi very conspicuous, porrect ; third joint fairly robust, 

 long, slightly curving downwards, bluntly pointed. Fore wing : 

 costa straight, apex broadly truncate ; inner and outer margins 

 subequal ; cell almost two-thirds the length of costa; vein 12 

 reaching costa far before the end of cell ; vein 8 usually given 

 out beyond the end of cell — that is, veins 7 and 8 anastomose for a 

 portion of their basal length (this is not an invariable character ; the 

 length of the anastomosis varies in different specimens, and occa- 

 sionally, though very rarely, veins 7 and 8 are free for their entire 

 length) ; discocellulars taken together forming a curve, the lower 

 the longer ; vein 3 shortly before the end of cell ; vein 2 con- 

 siderably nearer to vein 3 than to base of wing. Hind wing : outer 

 margin with a tooth-like projection at vein 7 and a second more 

 prominent one at vein 4 ; from this latter projection to the anal 

 angle the margin is perfectly straight, thus giving the wing a 

 very squared appearance. Neuration of hind wing much as in 

 Odontoptilum. Hind tibife with two pairs of spurs, the upper pair 

 minute. Male with a long tuft of hair attached to the proximal 

 end of hind tibife.

This genus is closely allied to Caprona and Odon(optth/in ; the 

 sharply pointed anteniue, however, will at once separate it. 

 Confined to Asia. 



31. Genus Tapena. 



Tapena, Moore, Lep. Ceyl. i. j). LSI (1 88 1). 



Type, thwaitesi, Moore. 



Antennae : club moderate, hooked, tip acuminate. Palpi con- 

 Sjjicuous, porrect ; third joint, short, obtusely conical. Fore wing : 

 apex broadly truncate; inner and outer margins subequal ; no costal 

 fold in male; cell less than two-thirds the length of costa; vein 12 

 reaching costa before the end of cell ; discocellulars suberect, the 

 lower the longer ; vein 3 shortly before the end of cell ; vein 2 

 about twice as far from end of cell as from base of wing. Hind 

 wing : outer margin sinuate, produced at vein 3, giving the wing a 

 squ.ired appearance ; vein 7 well before the end of cell ; disco- 

 cellulars and vein .5 faint ; vein 3 immediately before end of cell ; 

 vein 2 considerably nearer to end of cell than to base of wing. 

 Hind tibise with two pairs of spurs. Male with a tuft of long hair- 

 like scales attached along the inner side of the hind tibiae. 



The species agni differs from the type in the outer margins of 

 both wings being even, but agrees with it in all other respects.
