been notorious for its extremely polyphagous habit. Its distribution also is more 
or less cosmopolitan and one often finds lists of food-plants on which it is usually seen 
feeding published separately for each country. I give below a list of hosts from 
which the insect has been collected by myself in Lahore and the neighbourhood. 
The most favourable hosts and those upon which it may be observed feeding almost 
any day throughout the winter, in company with Szphocoryne indo-brassicae, are the 
plants belonging to the Natural Order Cruciferae and more particularly to the various 
species and sub-species of the Genus Brassica. But it can live and reproduce on 
almost any green and succulent plant. The list includes several plants which this 
insect has not been reported to infest in other countries; and, though a fairly large 
one, does not pretend to be at all exhaustive.
