gently arched, apex and termen evenly rounded ; 7 to apex ; white ; a moderate 

 very undefined basal fascia of blue-grey suffusion ; a large yellow-ochreous 

 patch occupying posterior f of wing except a white marginal streak, edged 

 with blue-grey and finely streaked with blue-grey on all veins ; cilia white, 

 with a blackish-grey basal line round apex and termen. Hindwings light grey ; 

 cilia |, whito, with a faint greyish basal line. 



Eleven specimens, all bred, Neboda, Ceylon, in March and April (Green) 

 Larva rather flat, at first reddish, afterwards creamy-white; constructs flat 

 canopies and galleries of fine silk and comminuted fragments of bark on stems 

 of H'evea bras'liensia Para rubber) ; feeds on lichens and alga? growing on stem ; 

 when pupating, a flattened cocoon or case, with valvular opening, is formed 

 in a shallow depression beneath the silken canopy (( reen). From specimens 

 sent, however, I should suppose that the bark itself is freely used as food. A 

 very elegant insect, allied nearly to C. olympia, but very much smaller.
