" Head small. Antmna rather short. Forewing acutely pointed and produced, or 

 sharply angulated, at the apex ; its inner margin straight in both sexes, not being lobed at the 

 base in the male as it is in Clerome and less distinctly in Thaumaiitis ; the coslal nervure 

 reaching to the end of the fifth seventh of the length of the anterior margin ; the subcostal 

 four-branched, the first branch given off just before the end of the cell, and, after running free 

 for nearly the same distance beyond that point as it originates before it, completely coalescing 

 with the costal, but again becoming free just before this last named nervure turns off to the 

 anterior margin ; the three remaining branches free. IIindwing more elongated than, and 

 not quite so rounded as, in Clerome ; without the pencil of erectile seta" which, in the males 

 of Thauviantis, arises from the wing-membrane of the discoidal cell close to the 

 subcostal nervure, and lies obliquely across a patch of elevated and crowded scales on the 

 other side of this nervure, the male scent-fans, if such are really present in this genus, being 

 situated in a different part of the wing, viz., in the anal region, where a line of setic running 

 along the anterior side of the submedian nervure ends in a curled whisp which, when at rest, 

 lies in a slight groove or fold of the wing-membrane. In the form of the hindwing and in the 

 position of the male scent-fans yEmona agrees best with Xantliotccnia, and in its pointed fore- 

 wing with Zeuxidia, Enispe, and Discop/iora, but it diflfers from these and from all the other 

 Indian genera of MorphintE in the relations of the costal and subcostal nervures to one another, 

 and in other respects." ( Wood-Mason, 1. c.) 



The genus ALmona is confined to the north-east corner of India extending into Upper 

 Tenasserim. It contains three species only ; they are " plain and delicate butterflies of a pale 

 fulvous colour, inconspicuously or obsoletely ocellated on the underside." ( Wood-Mason, I. c, 

 p. 176). ./E. lena is a very distinct species ; ^E. aviathusiasiivl AL. pealii are very closely allied, 

 differing chiefly in the apex of the forewing, which in the former species is sharply produced ; 

 in the latter more rounded. Nothing is known of the habits of any of the species, and all of 

 them are veiy rare. We have not seen a female specimen of any of the species, 



Eey to the species of ^niona. 



A. Forewing produced and pointed at the apex, with its outer margin concave-sinuous.

Habitat : Upper Tenasserim. 



Expanse: <?, 3-25 inches. 



Description: Male: "Upperside : /^r^rt//;?^ pale brownish grey, crossed by a dark 

 brown band, interrupted by the nervures from before the apex to near the posterior margin at 

 two-thirds of its length from the base ; beyond the band darker, with a slightly marked and 

 incomplete submarginal line, before which is a series of five pale lanceolate blotches between 

 the nervules directed towards the outer margin. All the nervures tinged with yellow, and 

 more or less dark-bordered. Hindwing: Anterior portion from base to outer margin pale, 

 posterior portion bright yellow, crossed by a submarginal series of three dark-bordered white 

 blotches, and a fourth fainter blotch between the nervures, forming a short interrupted band 

 from near the apex to the second median nervule. The submedian nervure fringed from its
