84 LEPIDOPTEBA INBICA. 



jSToTE. — "We have carefully examined Felder's type of mm, and find it to be 

 identical with the tailed form of ardates, as Bingham (who had not seen the type) 

 suoo-ested : there are three males, all from Amboina, in the Felderian collection at 

 Tring, and a female with yellowish underside, and all are true ardates.

Imago. — Male and Female very similar to nora above and below, but without 

 tails. Genitalia also conspecific. 



Expanse of wings, ,? ? t% to 1 inch. 



Habitat. — India, Burma, Ceylon and nearly (if not quite) all the islands of the 

 Malay Archipelago. 



Distribution. — Felder's type came from Ceylon, it is not now in the Felderian 

 collection at Tring ; it is undoubtedly the insect that has heretofore been called the 

 tailless form of ardates, which is very common in Ceylon ; it is found in most of the 

 localities in which 7iora = ardates is found, but in certain localities where nora is 

 plentiful this tailless form does not seem to exist. In all the years we collected in 

 Bombay, where nora is very common, we never took a single specimen ; and de Niceville 

 says (p. 154), in the Bombay Presidency, Burma and the Andamans, only the tailed 

 form is to be found ; de Niceville says they occur together in Masuri, Sikkim, Malda, 

 Shillong-,- Orissa, the Nilghiri and Shevaroy Hills and Ceylon ; but that does not prove 

 they are one and the same species ; Green, who is a careful observer, says, " The tailless 

 form of ardates differs distinctly in its habits from the tailed form, sporting about in 

 large clouds round the Madras thorn-trees in Colombo ; the specimens of ai^dates that I 

 catch up-country are never seen but singly or in pairs, and have a more hesitating 

 flight." de Niceville says W. C. Taylor at Orissa, G. F. Hampson at Ootacamund, as 

 well as E. E. Green at Colombo, all consider these forms to represent distinct species. 

 We have the tailless form from Sikkim, the Khasia Hills, Chota Nagpore, Orissa, from 

 Flores, and many of the islands of the Malay Archipelago ; and we have always 

 believed it to be distinct from the tailed form. Watson also says, " Noreia = ardates is 

 either very variable or more than one species is included under the name ; the tailless 

 form appears to be much rarer in this district. I only obtained four specimens, three 

 from the Upper Chindwin in February and March, and one from 3,500 feet in June."
