Life History, 
This insect was found by Mr. S. Carr seriously defoliating 
teak plantations in the Rangoon Division in June-July rg02 
Mr. Carr states that it defoliates the trees in a similar way to the 
larvee of the moth Pyrausta macherals, t.e., by eating only the 
soft parenchyma and thus skeletonizing the leaf. This statement 
is one of considerable importance and requires careful extended 
observation since it has been up to now supposed that this 
method of defoliation was peculiar to Pyrausta macheralis. 
Mr. Carr mentions observing large numbers of small yellowish 
moths about the same time in the plantations, and these are not 
at all unlikely to have been those of P. macheralis, in 
which case this skeletonizing may have been done by the 
larve of these moths, they having all pupated before they 
were noticed at work. Further, it may be that the JZ. 
constellata larve feed upon the soft parenchyma in their 
younger stages of growth. ‘this point requires careful observa- 
tion and a careful comparison of leaves defoliated by the two 
larve. 
The June attack was a serious one as it spread over goo 
acres of plantation. The damage was said to be unevenly 
distributed and appeared to be the result of numerous separate 
attacks, each commencing at a centre of its own and extending 
irregularly in all directions to a distance limited only by the life 
of the caterpillars. The larve of this June attack are said to 
have pupated on the leaves, enormous numbers of pupe being
