Belenois JAVA, SjDarr. {coronea, Ci\). 



Coast of Sambawa, common, not seen in Sumlba. Cramer records 

 this species from Borneo, and in the Singapore Museum there is a 

 specimen labelled Jelebii (not far from Malacca). These localities are 

 certainly doubtful, as the butterfly inhabits diy, sterile coasts, and 

 would be quite out of place in forest countries like Malacca or Borneo. 

 On the other hand a coast-butterfly of exceedingly weak flight, but able 

 to float in the air for an indefinite time, would be more apt to be blown 

 out to sea than other insects, and more likely to survive till its arrival 

 in another island. So that stragglers may really have been taken 

 remote from the true habitat of the species. 



This butterfly flies like a Hestia, and seems to be the most perfectly 

 protected of Easteim Pieridce. It is hard to believe that it has any- 

 thing to do with the Indian Belenois mesentina, the type of the genus, 

 which is wholly different in appearance and in habits. Like Delias and 

 Prioneris this genus has the claws bifid. 



Delias pasithoe, Linn., var. 



I saw two specimens of this on Mt. Harahasa in Sambawa at 

 nearly 5000 feet elevation, but as well as 1 can remember neither were 

 taken. An undesci-ibed Agarista mimicking it was caught at the same 

 place. No species of Delias was observed in Sumba. 



Delias oraia, n. sp. 



A local form of the Indian Delias descomhesii, and greatly resem- 

 bling it. It lacks, however, the black marginal band of descombesH, the 

 costa and outer margin of both wings being slenderly grey, especially 

 at the ends of the veins, the cilia lemon. Below the five subapical lunules 

 on the forewing are yellow, not white. The female is generally brighter 

 coloured than that of descomhesii. The hindwing, however, is much 

 darker over the base and disc, but below the submarginal spots are 

 bright lemon, and the hind-margin rich ochreous. 



Sambawa, 2 — 5000 feet, scarce. The specific name means beautiful 

 in modeim Greek. I thought it unnecessary to give my detailed de- 

 scription of the species. 



The reappearance in Sambawa of a local form of an Indo-Malayan 

 butterfly unknown to Java, is remarkable.* 



* I take the opportunity to describe a new Javanese species of this genns. 



Delias aurantia, u. sp. 

 Near D. belisama, Or. Above orange over the basal half of the wings, including 

 all the cell, the disc as far as the upper radial vein, far beyond the cell, and the hind
