99. Castalius ethion^ Doubleday and Hewitson. (No, 761.) 



This is a local little butterfly, found in particular limited localities 

 all over the district, and noticed at all seasons. 



The caterpillar, which feeds on young shoots of Zizyphus jitjuha, 

 is of the woodlouse form, but flattened. Its texture, though appa- 

 rently smooth, is, if looked at with a lens, found to be thickly covered 

 with white hairs ; its colour is greenish-white with a faint, green, 

 dorsal band. 



The pupa is similar in shape to that of C. rosimov^ Fabricius, but 

 smaller and narrower. It is of a bright apple green, with a darkish 

 green line down the centre. There are some small red dots on the 

 edges of the wing-cases. The larva and pupa are figured on Plate IV, 

 figures 4 and 4a. 



100. Castalius deeicUa, Hewitson. (No. 766.) 



This is the commonest species of the genus, and its larva and pupa 

 were described in our former paper. It feeds on Zizijphus rugosa, and 

 may be known from that of G. eihion, Doubleday and Hewitson, by 

 having two green bands on the back instead of one. The butterfly 

 is common everywhere at all seasons. 



101. Polyommatus bceticus, LinnaBUS. (No. 767.) 



Fairly common above the ghats in the cold and hot weather, and 

 possibly so in the rains. Below, in the cold weather, sparingly found 

 in places on the immediate coast. We have not noticed it during the 

 rains. The larva feeds on the buds of l^uor {Cajamis indicus), and 

 fields of that grain swarm with the butterfly in February. We also 

 got great numbers ii larvse on Butea frondosa. They were of the 

 usual form, bat much corrugated : head yellow with a black cheek 

 spot, margin fringed with short hairs, anal portion rounded ; colour 

 obscure yellow. 



Pupa almost similar to that of Catochrysops pandava, Horsfield, 

 but more rounded ; it is formed loosely on the ground, or in some 

 cases under a clodj the larva falling with the withering flower. 



102. Amhlypodia anita, Plewitson. (No. 771.) 



A common butterfly in the hot weather and in the earlier half of the 

 rains wherever there is evergreen jungle. Also occasionally noticed 

 during the cold weather. The caterpillar is a very striking object. 

 It is of the woodlouse form and large for the size of the butterflj'^^
