the top of the other and diagonally across it ; the cell is thickly lined with silk, so that 

 it is difficult to tear it ; an aperture is left in front where the midrib has been gnawed 

 through. The larva is of slow growth, and is very much attacked by spiders, birds, 

 wasps, etc., notwithstanding its strong retreat ; it is caught when out feeding. 



The insect is common throughout the district at all seasons ; the golden yellow or 

 brown form in the dry season ; the dark form in the monsoon months ; these two forms 

 differ from each other just in the same degree that C. tmjlori, de Niceville, differs from 

 C. ransonnetii, Felder. The insect is easily captured as it is resting on a leaf, stone, 

 etc., near the ground; it is fond of shade. Both forms have been bred plentifully by 

 us. (Davidson, Bell and Aitken.) 



Habitat. — India, Ceylon, Burma. 



Distribution. — The type is marked Bengal ; we have many examples of both the 

 wet and dry season forms from Sikkim, Assam, Madras and Karwar, and have examined 

 many others from various localities ; it is a common species throughout India and 

 Burma ; the uposatha of Friihstorfer is the extreme dry-season form ; our figures of the 

 larva and pupa are from Davidson's drawings not previously published ; we have 

 examined the examples in his collection, they are all marked " rains," all have 

 checkered cilia, and are not tissa, but the wet-season Ijrood of indrani.

Imago. — Male. Upperside rufous-brown. Foreicing with three semi-hyaline 

 small white sub-apical .spots from near the costa, the middle one the smallest and well 

 inwards ; in some examples one or both of the lower spots are absent ; a large semi- 

 hyaline spot inside the cell, near its end, its inner side square, its outer side deeply 

 excavated, with a small spot between it and the costa, a small round spot near the 

 base of the second median interspace, a much larger round spot in the middle of the
