beginning on the oldest and toughest leaves, like pieces of dark-green 

 morocco leather. 



56. Delias euchmm, Drury; 



Larva long, cylindrical and smooth, with an oily gloss, Two 

 subdorsal rows of long white bristles springing from minute white 

 tubercles; head, sides and back sparsely clothed with short white 

 bristles; colour brown, head and feet black. It may be found 

 from the beginning of August everywhere, on the common 

 "misletoe" (Lorantlms), from which it will drop and hang by a 

 thread if the tree is shaken. We have never found it feeding on 

 anything else. Unlike most butterflies, this species lays as many as 

 twenty or thirty eggs on one leaf, in parallel rows, with equal in- 

 tervals, and the larvae continue in some measure gregai'ious to thelast, 

 so that a large number of pupae are often found, at little distance from 

 each other, on a wall, or the trunk of a trcu, 



The pupa is closely attached by the tail and by a band, generally to 

 a vertical surface, with the head upwards. It is moderately stout, 

 with a short snout, two small tubercles on the head, a sharp but 

 not prominent, dorsal ridge on the thorax, continued in a row of 

 tubercles on the abdominal segments. Below these are two partial 

 subdorsal rows ; colour bright yellow ; tubercles and a row of spots 

 defining the wing-cases black. 



Large numbers are destroyed by a dipterous parasite, very like a 

 common house-fly. 



57. Appias Ubythea, Fabricius. 



We did not get this in Canara, but reared a good many in Bombay 

 daring April and May, on udppcirts liorrida. The larva is long, green, 

 somewhat depressed, and has the rough surface and general aspect of 

 a Terias, or a CatopsUia, but the anal extremity tapers a little, and is 

 slightly but distinctly bifid. The pupa is of quite a different 

 type from Terias or CatopsUia. It is closely attached to a leaf, and 

 the wing-cases do not forma keel, but there is an acute dorsal promi- 

 nence just behind the head, and a transverse dorsal ridge in the 

 middle connecting two angular, lateral processes. The head ends in 

 a short snout. The colour rs \ unable, and probably depends on 

 situation.
