It has been seen that the larvae live in the wood of living trees, 
and observations have shown that they will desert trees which 
have been cut down and the wood of which has consequently 
begun to dry. On the 22nd September of this year (1903) my 
attention was drawn to a small Cassia nodosa in the Indian 
Museum compound, which was evidently in a dying condition, 
the spring crop of leaves having all dropped and no new ones 
having replaced them. Examination showed that the tree was 
infested by the larvae of this moth, several holes with half-pro- 
truding empty pupal cases being perceivable. The tree was 
only 15 feet high with a girth of twenty inches at the base. It 
was much branched all the way up and had a whippy spreading 
crown. Lhad this tree cut down and placedin a large wire. 
gauze cage. In addition to two half (or less) grown larve and 
some live pup (taken to preserve in spirits) the following 
moths were obtained from the stem as they issued on the dates 
noted. [A portion of this stem, with the empty pupal cases 
tn situ protruding from the bark, is now exhibited in the 
Insect Pest Gallery at the Indian Museum: the other half has 
been sent to the British Museum (Vide fig. e.).]
