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



559. Hiposcritia cardena, Hewitson. 



Grose Smith. Snellen. Wallace. Distant. Hagen. Quite as 

 common as H. pandione, Hiibner, and occurs in the same localities 

 throughout the year. No female obtained. 



560. Saletara nathalia, Felder. 



Grose Smith. Snellen as panda. Hagen. Wallace. Distant as 

 nathalia and panda. Mr. Distant records both S. panda, Godart, and 

 S. nathalia from the Malay Peninsula and Sumatra. Dr. Wallace con- 

 siders that 8- panda is confined to Java, while S. nathalia also occurs in 

 Java, and in the Malay Peninsula, Sumatra, Borneo, the Philippine 

 Isles, and Celebes. 8- panda in the male is known by the pale primrose- 

 yellow colour of the upperside, while S. nathalia is " creamy white with 

 a faint greenish tinge." I greatly doubt if this character is sufficiently 

 constant to separate the two species, I have one specimen from Sumntra 

 which is quite intermediate between them. Mr. Distant considers that 

 S. nathalia having five [three according to my way of computing 

 them] subcostal nervules to the forewing in the male, while S. panda 

 has only four [two], while the females of both species has four [two], 

 is a character by which the two species may be separated, though 

 he admits that he has a specimen of S. nathalia in which one wing 

 has the neu ration of S. nathalia, while the other has that of 8. panda. 

 In my series of thirty males of this genus, I have one from the Philip- 

 pines aud one from. Singapore with two subcostal nervules only, one 

 from Singapore, one from Great Nicobar, and one from Little Nicobar 

 with two subcostal nervules on one side only and three on the other, 

 while all the rest have three subcostal nervules on both sides. The 

 females seem to be more constant, having two subcostal nervules only in 

 all the specimens I have been able to examine. Neuration certaiuly 

 will not suffice to keep these two species distinct. I use Felder's name 

 for the species as most of the writers on Sumatran butterflies have done 

 so, and as the majority of male specimens from thence agree with the 

 description of that species rather than with that of 8. panda, the older 

 name. It has been beautifully figured by Heer P. C. T. Snellen as Pieris 

 panda, Godart, in Midden-Sumatra, Lepidoptera, pi. ii, figs. 9, 10, 

 male; 6, 7, female (1892). It is found only in the forest at low ele- 

 vations, not higher than Namoe Oekor as far as we have noticed, but 

 Dr. Hagen mentions its occurrence on the Central Plateau. Not at 

 all common, and flies from March to July. The Saletara sclioenbergi 

 of Semper, described from Nias and South-East Borneo, also from Great 

 and Little Nicobar in my collection, has been described and figured by
