434 DUOMITUS LEUCONOTUS, Walker. 

In addition to these 32 moths there were two others which 
never acquired their proper wings, on issuing, probably due to 
the handling the chrysalids received. It is probable that at 
least 40 moths left this tree during September and October. 
In addition to the small Cassta nodosa iree, which may be 
said to have been killed by this insect during 1903, a much 
larger tree, some 35 feet high and 3 feet in girth, has been 
attacked, more especially at its base, as evidenced by several 
empty pupal cases protruding from the bark surface, 
Protection. 
The moth was noticed in various parts of Calcutta during 
the above-mentioned weeks, and was evidently this year fairly 
abundant. We have yet todiscover what other trees it infests - 
in addition to the Cassta nodosa which Major Prain, who very 
kindly identified the tree for me, tells me was originally sent 
to the Museum from the Royal Botanic Gardens at Sibpur. 
Points tn the life-history requiring further observation. 
1. Length of time spent in the larval stage. 
2, Number of eggs laid by the female insect. 
3. The different species of trees infested.
