grows slowly, spends most of its time at rest, motionless, on the 

 upper side of a leaf of precisely the same tint as itself. A dorsal 

 line, or row of spots, however it may look on paper, succeeds in 

 keeping up the continuity of the midrib of the leaf in a way which 

 cheats the sharpest eye, while the long interlaced spines, extending 

 on each side, fall in with the neuration. In E. garuda the dorsal 

 line is light yellow, touched with blue, and the spines are fringed 

 with yellow* The pupa hangs by the tail on the underside of a leaf, 

 often the very one on which it spent its larval life, for it is too 

 cautious an insect to eat the leaf it lives on. E. garuda commonly 

 feeds on the mango and the cashewnut tree, but we have found it on 

 the mulberry and the rose, and on Loranthus along with the next 

 species. The first brood of larvae was found about the end of June, 

 and the butterfly swarmed in July. About a month later larvae 

 became very plentiful again and so continued until we went into 

 camp in the beginning of November, and had to give up keeping 

 them. They certainly lasted till December. 



33. EuthaUa lubentina, Cramer. 

 This was found in August, September and October on two common 

 species of the so-called " Mistletoe " {Loranthus). It probably con- 

 tinued till the end of the year. In form the larva resembles the 

 last; in colour it is grass- green, but the dorsal area of most of 

 the segments, between the spines, is brown or claret-coloured, with 

 or without a pure white diamond in the middle. The spines are 

 tipped with the same shade of brown, and it is worthy of note that 

 the leaves of Loranthus are often disfigured with spots or patches of 

 this tint. The pupa is green with a small brown patch on each side : 

 it wants the gilt edging of E. garuda, and the dorsal triangle is more 

 sharply pointed. For lovers of the marvellous it may be worth 

 mentioning that the caterpillar of E. lubentina, when it has cast its 

 skin, spines and all, cats it. 



34. EuthaUa kpidea, Butler. 



Larva of the usual EuthaUa form ; colour green, with a dorsal row 

 of light red ocelli with blue centres; spines tipped with yellow. Pupa 

 more narrowed at the head than E. garuda ; green, all the points 

 golden yellow tipped with black, and a few large spots of gold be-
