We find that the following species fall within the above definition : — 



1 (10). Hind wing above plain brown. 



2 (9). Hind wing below brown, with or without a whitisli border round the apex. 



3 (6). Cell-spot present on fore wing above. 



4 (5). No sex-mark on fore wing above in the male. Fringe of hind wing not 



yellow in the tornal region. Hind wing below frequently more or 



less broadly whitisb round the apex calathus, Hew. 



5 (4). Sex-mark on fore wing above in the male linear, blackish, erect from 



the middle of vein 1 a to the basal third of vein 2, thence oblique to 



near the base of vein 3. Fringe of hind wing yellow in the tornal region, zeus, de Nicev. 



6 (3). No cell-spot on fore wing above. 



7 (8). Hind wing above in the male with a tuft of long haii-s near the base 



completely covering the cell ; the latter very short, about one-third 

 as long as the wing, transverse vein suberect, veins 3, 4, and 6 

 equidistant at the base and much thickened in their basal half. Hind 

 wing below brown, yellowish next the transverse vein zenon, de Nic^v. 



8 (7). Hind wing above in the male normal ; below brown, with a sharply 



defined yellow transverse band from the apical third of the costa to 

 the basal third of the dorsum but interrupted in cell 1 b. No cell-spot 

 on the fore wing above avesta, Hew. 



9 (2). Hind wing below brown, with a white median band from the costa to 



vein 1 b, the breadth of this band equal to half the length of the wing, mytheca, Hew. 



10 (1). Hind wing above in part yellow. 



11 (13). Fore wing above with a cell-spot, no pale spots in cells 6, 7, or 8. Hind 



wing below with a yellow band having the same direction as in avesta. «araZa,de Nicev. 



12 (11). Fore wing above with a cell-spot and a pale spot in each of cells 6 and 7 



or 6, 7, and 8. Hind wing below with a broad yellow band from the 

 middle of the costa to the middle of cell 1 b, sometimes continued to 

 the dorsum excelhns, Stgr.

We have been obliged to unite the three supposed species of Lotongus upon which 

 Mr. de Niceville has written, we think, without sufiicient material. We possess specimens
