BY MISS A. E. PROUT. 239 



Mt. Dnlit, 3000 feet— 1 cf- There are also before me 2? 

 from Kedab Peak, 3200 feet, December, 1915, submitted to 

 US by tbe Eaffles Museum. A single specimen from Negri 

 Sembilan, previously submitted to us and returned as 

 (probably) merely an aberration of incongrualis , evidently from 

 my notes (as well as from tbe locality) belongs to this 

 subspecies ; this last was an extra fine specimen, about 30 mm. 



Like the last species, this appears really to belong to a 

 new genus, for which Sir G. Hampson has a name in MSS ; 

 but to avoid collision with this MSS name T publish the 

 subspecies under Marapana, the genus in which inconqrualis 

 was placed in the Moths of India, probably the latest generic 

 name employed for it and certainly rather more suitable than 

 Hijpena. 



64. Mecodina hybrida sp. n. 



$ 47 mm. 



In size, shape and tone of colour hybrida resembles a pale 

 9 of M. alhodentata, Oqlasa alhodentata Swinh., Ann. Mag. 

 Nat. Hist. (6), xv, p. 13, 1895, Khasias, from which it differs 

 in the following particulars. Segment 2 and 3 of palpus both 

 appreciably shorter ; fore and hind v.ing both slightly less 

 sharply angled at middle ; medial line bent inward in cell as 

 well as in fold ; reniform broader, with a slight line at middle 

 (less distinct) ; postmedial line more dentate on R' and M^ ; 

 the subapical triangular dark spot not followed by a dark 

 streak to the termen ; the waved metallic-blue line of alho- 

 dentata replaced by subterminal white spots on the veins, 

 more as in Psimadn quadripennis Wlkr., Spec. Lep. Ins., 

 XV, p. 1828, 1858. Canara. Similar subterminal white 

 spots on the hind wing, followed by a pale buff terminal 

 shade from M^ to tornus. Underside a little greyer than in 

 alhodentata, with the white marks on costa of fore wing and 

 the dark IJnes less sharply defined, but the slight pale 

 subterminal spots on the Aeins as above ; both wings with a 

 slight rufous tinge towards costa. 



Mt. Mnrud, November — 19 holotype. A damaged 9 in 

 Coll. Joicev from S.W. Sumatra, North Ivorintji Valley. 

 5000 feet. 'September-October. 1921 (C, F. & J. Pratt), 

 seems to match the type of hybrida. 



This species forms somewliat of a link between alhodentata 

 and qiiadripennis, which Sir G. Hampson retains in separate 

 genera, apparently on the strength of a not-very-apparent 

 difference in the scaling of segment 2 of palpus. As a matter
