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



occurs, and it has the same habits as G. erotoides. As Dr. Martin never 

 obtained the latter species from places higher than Bekantechan, and 

 never true G. battaka from places lower than Bekantschan, and as both 

 species occur quite at the same time, there can be no question here of 

 seasonal dimorphism. Dr. Martin notes that he is quite sure G. battaka 

 is a good species restricted to the mountainous regions of our area. 

 He notes also that he has received some specimens of G. battaka from 

 Java, but without exact locality, and hopes to hear later at what 

 elevation they were obtained, as G. erotoides occurs also in that island. 

 Dr. Martin further notes that he obtained one female of G. battaka, 

 which differs greatly from the female of the former species, these 

 differences are pointed out in his original description of C. battaka, 

 (1. c). 



139. Apatura namouna, Doubleday. 



Hitherto this species has not been recorded south of Upper Burma, 

 its re-appearance in Sumatra is most interesting. In our area it is a very 

 rare butterfly, and is found only on the higher hills at an elevation of 

 not less than 3,000 feet, and from the Central Plateau and the Gayoo 

 mountains. The specimens from Sumatra are decidedly smaller than 

 those from Northern India, but do not otherwise differ. No female 

 from Sumatra has been obtained. 



140. *Apatora parvata, Moore. 



Grose Smith. This is almost certainly a wrong identification, 

 A. parvata being restricted to Sikhim and Bhutan. The specimen Mr. 

 Grose Smith obtained was probably a female of the next species. 



141. Apatdra (Rohana) sumatrensis, Staudinger. 



A. (Rohana) parisatis, Westwood, var. sumatrensis, Staudinger, Iris, vol. ii, 

 p. 80 (1889). 



A. parisatis, Snellen (nee Westwood), Midden-Sumatra, Lepidoptera, p. 19, n. 1, 

 pi. iii, figs. 1, male; 2, male underside x 2 (1892). 



Snellen as parisatis. Hagen as parisatis. Staudinger as parisatis, 

 and parisatis, var. sumatrensis. Semper as camiba. The male maybe 

 known from the N.-E. Indian and Burmese species, A. parysatis, West- 

 wood, by having a small diffused apical ferruginous patch on the up- 

 perside of the forewing, which is absent from the continental species. 

 The females of the two species differ but slightly. Like Atella alcippe, 

 Cramer, this insect only appears on red soil (probably the food-plant 

 of the larva grows only on that soil), where the males from Selesseh 

 to tho higher hills are not rare, whereas the females are always scarce,
