448 h. de Niceville & Dr. L. Martin — Butterflies of Sumatra. [No. 3, 



Martin obtained only two males of this rare species at Bekantschan in 

 March and May. 



305. Poritia Sumatra, Felder. 



Felder. Butler. Grose Sniith. Kirby. Distant. Originally des- 

 cribed from Sumatra. A very distinct and easily recognised species 

 which shews but little variation. Occurs in the Battak mountains. 



306. PoRrriA erycinoides, Felder. 



Grose Smith. Hagen. Felder originally described and figured a 

 male from Java, Hewitson described and figured the female as P. plira- 

 atica from Singapore, the latter being black on the upperside marked 

 with orange. I have a good series of both sexes from Java, which 

 agree with Sumatran ones from the Battak mountains. 



307. Poritia pleurata, Hewitson. 



The type of this species was from Singapore. The male may be 

 known from P. erycinoides, Felder, by having the apical half of the fore- 

 wing on the upperside black and unmarked instead of heavily marked 

 with blue. The female of P. pleurata is marked with blue in some 

 lights, green in others. Occurs in Sumatra at Bekantschan. 



308. Poritia promula, Hewitson. 



Originally described from a female from Java. Dr. Martin possesses 

 female specimens which agree very well with Hewitson's figures and 

 description. 



309. Poritia philota, Hewitson. 



Hewitson. Grose Smith. Kirby. Originally described from 

 Sumatra, where it occurs at Selesseh and in the Battak mountains. It 

 is found also at Pahang and Johore in the Malay Peninsula. The 

 female is unknown. The male is easily distinguished by the very 

 dark colour of the underside, Mr. Hewitson calls it " rufous-brown, un i 

 dulated throughout with paler colour." I would describe the ground- 

 colour as fuscous, the macular bands very close together, dark ferru- 

 ginous in colour, outwardly defined with black. 



310. Poritia platemi, Staudinger. 



P. plateni, Staudinger, Iris, vol. ii, p. 104, pi. i, fig. 8, male (1889). 

 Originally described from two males from Palawan in the 

 Philippine Isles. It is a most distinct species, all the bands of the 

 underside present in every Poritia are in this species broken up into well- 

 separated spots. The Poritias in the male sex have perhaps on the
