Family (ii:o}[KTRl DAK. 



Subfamily OENOCHROMINAE. 



Hypophracta gen. mof. 



Sfrncture and general appearance of Conolopliia Warr. ; nenration identical; 

 inner mar£;in of hindwing in S withont cone of hairs ; but instead the fifth abdominal 

 segment is swollen beneath so as to form a ridge with Interal projections, armc 1 

 with short tnfts of hair; the sixth segment beneatli also bears a loss consj)icaons 

 ring of hairs ; the penultimate segment above has two lateral npcnrved tnfts ; and 

 the tnfts of the anal segment are strongly developed : the hind legs of the S 

 have a long pencil of hair on the inner side of the tibiae, rising from the femoro- 

 tibial joint. 



Type : Hypopkractfi persiinilis spec. nov. 



5. Hypophracta persimilis spec. nov. 



Forciriiifi : bone-colonr tinged with pale brownish red and sjn-inkled with 

 fnscons atoms; the base and costal streak greyer ; first line vertical, from one-fourth 

 of costa to one-third of inner margin, marked by dark spots on the veins ; cell-spot 

 similar ; outer line straight and oblique, dark brown, from below four-fifths of 

 costa to two-thirds of inner margin, the central space preceding it paler, the 

 marginal beyond it darker than the rest of the wing ; submarginal line very obscnre, 

 marked (in the single example, which is not fresh) by a brown spot on costa and 

 a second below vein 7 ; a row of distinct brown marginal spots between the veins ; 

 fringe bone-colour. 



Iliniiiriny : without first line ; the dark transverse line central, not reaching 

 above vein 6. 



Underside paler, with nnmerons grey speckles ; cell-spots and onter lines grey ; 

 submarginal spots as above. 



Head, thorax, and abdomen bone-colonred ; shonlders and base of patagia

Superficially scarcely distinguishable from Co/io/oj'/i/a conscitKria Wlk. 



Subfamily ORTHOSTIXINAE. 

 Genus Derambila Wlk., xxvi. p. 10:1(1 (1862). 



The genus was erected by Walker for a West African species, piaietisiipmta, 

 to which, if not, as I belie\T, identical, Butler's Rambftra piiella from Madagascar 

 mnst be closely allied. 



There seems to me no real structural ditference between the African and Indian 

 insects ; and the name Drntiiiljila should stand fur Hninhitni Moore, the generic 

 term which was instituted to distinguish the Old Worhl species from those of the 

 American /ancloi/teri/x. 



The genus Cluonopterj/x Snell., I'ijd. c. JCnt. 1873. p. 72, is probably only an 

 extreme development, if that, of JJerainbila .
