198 RHOPALOCEKA MALAYAN A. 



I have only descnbed such features of the neuration as seem to be peculiar and indicative 

 of the genus, and throughout this family shall pursue a similar course of treatment. 



The species of I'oritia exhibit a brilliancy of colour and markings which forcibly remind 

 a lepidopterist of the glories of the Neotropical Erijcuiidce, and in this respect the genus is, 

 I think, well placed at the commencement of the Eastern Ujcmmiai, The genus was founded 

 by Mr. Moore for the reception of a N.E. Indian species, but roritia has since been shown, and 

 principally by Mr. Hewitsou, to have its head-quarters and to reach its maximum of species in 

 the Indo-Malayan region. Some thirteen species are described, and of these no less than seven 

 are found in this fauna. Many of these are only known by the descriptions and figures of the 

 late Mr. Hewitson, and the typical specimens contained in his magnificent collection, and 

 I have failed to procure examples myself. It is perhaps idle to speculate on the number of 

 species of the genus which remain to be discovered in the Malay Peninsula, but they certainly 

 cannot be inconsiderable, and will eventually reward the efforts of an industrious collector.

Not having received this species, I have thought it best to copy Felder's diagnosis, with 

 his figures (supra). 



" <? . Alffi supra dilute virenti-cyanese, in certo situ vivide virentes, auticse plus quani bitrieute antico 

 vittulaque anali fuseis, posticas limbo costali margineque posteriore aute cilia fuscis."

This figure represents the female specimen collected by Capt. Pinwill and contained in the 

 British Museum,* which has been identified by Mr. Butler as belonging to Felder's species. 

 The differences, however, between that author's figure and the specimen thus identified are so 

 considerable that it is probable that the female of another species has been confused with that 

 of Felder. 



Hab. — Malay Peninsula; Penang; Malacca (Pinwill — Brit. Mus.) ; Singapore (coll. Hewits. t) — 

 Sumatra (Felder, and coll. Hewits.).
