Some difference of view exists as to the priority ol' the nomenclature of this species. 

 Mr. Kirby* records it under the name proposed by Prof. Westwood,— 7'. ((s/om/;,— but, after 

 perusing the explanatory note or almost pathetic remonstrance of Adam White, t there seems 

 scarcely any doubt that the usual course, and that followed by most writers, of giving White's 

 name priority, is inevitable.

Abdominal fold in male small ; anal valves small but swollen ; posterior wings caudately 

 produced. 



This section embraces a small group of species which are found in Continental India, 

 the Andaman Islands, Burma, the Malay Peninsula, and the islands of the ludo-Malayan 

 Eegion. 



These butterflies have a distinct facies by their elongately produced wings, the posterior of 

 which are caudately developed. Two species have been received from the Malay Peninsula.
