CUBETIS. 445 



near the base, above the subcostal vein, there is a short, broad, 

 black streak ; abdominal fold pale greyish white. Underside : 

 silvery white, the markings faint and ill-defined as in all forms of 

 Curetis ; the discal oblique band of the fore wing carried over the 

 hind wing, but not in any specimen that I have seen continued in 

 even a disjointed line (as in bulis) to the tornal angle. The rest 

 as in typical bulis. Antennae, head, thorax and abdomen similar 

 to those of bulis. $ . Very similar to that of bulis. Differs on 

 the upperside, in some specimens only, by the extent of the white 

 area on the hind wing, which spreads practically over the whole 

 wing, but is heavily shaded along the terminal margin and poste- 

 riori v on the dorsal area with dusky brownish-black or fuscous. 

 On the underside the ground-colour and markings are as in bulis. 

 Antennae, head, thorax and abdomen similar to those of bulis.

With regard to the larva I made the following note as far back 

 as 1891 : Mergui, 5th May, 1891. While passing through the 

 forest on the road to the Mergui plantations I saw a white female

Curetis fluttering over the leaves of a small Thin-win (Ponqamia 

 glabra, Vent.). Thinking she was ovipositing I approached and 

 carefully searched the leaves for eggs, but failed to find any. On 

 the leaves of a branch on the other side of the same tree however, 

 I found two small green larvae with crimson markings. Each bore 

 towards the anal end a pair of dark green erect horns. On trying 

 to break off the leaves on which they were feeding, the caterpillars 

 protruded a brown tentacle from each horn, crowned with a tuft 

 of black and white hairs ; these tentacles were whirled round 

 rapidly for a second or two and then withdrawn, and every time 

 afterwards when the leaf was moved or handled the action was 

 repeated. The same thing occurred if the larva was touched or 

 breathed upon. I took the larvse back to camp and reared them, 

 supplying them with the youngest and tenderest leaves of; the 

 Thin-win, which they riddled into holes along the midrib. Three
