XIII. On the Asiatic Lepidoptcra referred to tJie genus. 

 Mycalesis ; iritJi deseriptiojis of new genera and 

 species. By F. Moore, F.Z.S., &c. 



[Read October 6tli. 1880.] 



The Asiatic species of butterflies hitherto described 

 under the genus Mgcalesis are primarily divisible into 

 three groups : the first comprising species of which the 

 males possess a glandular-pouch (or scent-producing 

 organ) covered by a tuft of hair on both the fore and 

 hind wings ; the second group of species possessing it 

 on the hind wings only ; and the third of species which 

 have two on the hind wings. 



These three groups, again, are composed of a number 

 of forms mostly possessing a different vein structure. 

 Thus separated they fall into a natural assemblage of 

 species. 



I have not ventured into an examination of the 

 African species further than the determination of the 

 form and structure of the type of the genus Mijealesis 

 (viz. M. Eradne, Cramer) ; finding, however, that this 

 form has no congener among the Asiatic rei^resentatives, 

 and that most of the described African species are 

 generically distinct from Mijealesis, some of them, more- 

 over, having no affinity with that genus of Satyrince. 



Group I. With a glandular pouch and tuft on hoth. icings. 



N. g. ViRAPA. 



Fore wing with costa arched in the middle, apex 

 convex, exterior margin oblique and even, posterior 

 angle acute ; costal, subcostal, and median veins swollen 

 at the base ; first subcostal branch emitted immediately 

 before end of the cell ; disco-cellulars bent inward at 

 their middle ; radials from upper near the cell. Male 

 with a glandular patch of raised scales on the middle of 

 submedian vein, the patch being partially covered by a 

 tuft of long fine hairs exserted outward from each side of 

 the vein. Hind wing oval, exterior margin convex ; first 

 subcostal in male much curved upward at the base and 

 thence straight to apex, emitted at more than half 

 distance before end of the cell, second very concave from
