India (2—4), Ceylon (% 3) and the Kei Islands (New Guinea) (7). We have it 
from Galle (Ceylon), Gauhati and Pusa. It is probably widely distributed 
in India but has been overlooked. 
“Bred by Mr. H. Maxwell-Lefroy from pupz found on leaf of Averrhoa 
bilimbi ?, a tree of cultivation, so that it may be artificially spread” (?). 
These specimens were bred at Pusa from Averrhoa carambola. 
“The short, stout, uniformly-coloured larva feeds on the flowers of the 
‘bilimbi tree’ (Averrhoa bilimbi). The larve vary much in colour, hardly 
two being alike. Uniform yellowish-grey, pale yellow, pale greenish-yellow, 
pale green, pale pink, and red, are all common colours. (Plate F, figures 
5 and 6)” (3). The young larva bores into flowers of A. carambola at Pusa, 
the hole of entry being visible on the side of the unexpanded flower. 
“The pupa is a very pretty object, being usually a bright light green 
(sometimes with black markings) with numerous fasciculated tufts of yellow 
spiny hairs. The sketch (Plate F, figure 8)... . gives a good idea of its general
