Originally described from Java (^>, this species is known to occur in India (2— *), Ceylon (2. 3) and the Kei Islands (New Guinea) (2). 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 pupae found on leaf of Averrhoa hilimhi ?, a tree of cultivation, so that it may be artificially spread " (2). These specimens were bred at Pusa from Averrhoa caramhola. " The short, stout, uniformly-coloured larva feeds on the flowers of the ' bilimbi tree ' {Averrhoa hilimhi). The larvae 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. caramhola at Pusa, the hole of entry being visible on the side of the imexpanded 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 ( 1 )
