as already described for the latter. In the figure 1, 5 the pupa is 
shown spun on to a leaf. The pupal state lasts from 7-9 days in 
the case of the August generation, and a generation would 
appear to take about 5-6 weeks to run through. In fact, the life 
history, method of feeding, etc., appear to be identical with the 
true Yydlza, the only difference between the two insects being 
in the size and markings of the larva, pupa and moth. This is 
however very marked. 
In Burma from where it was also reported for the first time 
this year it was very plentiful in July but does not have ap- 
_peared to have reoccurred in August. 
Locality from where reported: Relations to forest, ete. 
This variety of Hyd/ea has been reported from the Nilam- 
bur Teak Plantations in India. It has also been sent from the 
Rangoon Division in Burma by Mr. S. Carr where it appa 
rently defoliates teak in company with Hyblea puera and 
FHyblea constellata. Its method of attacking the foliage and 
behaviour in the forest, etc., are the same as already described 
under 7. puera. 
Points in the life history requiring further observation, 
1. The number of generations in the year (this is im- 
portant) and the length of time spent in the various 
stages of egg, larva, pupa, and imago in each. 
2. Where the eggs are laid. Is it onthe branches and 
round the axils of the buds as is usual with noctuid 
moths ? 
3. Where the insect passes the winter and in which stage. 
4. Does it feed upon other trees besides teak? I believe 
this to be the case. 
Parasites upon Hyblea puera, var. nigra, MS. 
I. lchneumonitde. 
The caterpillars obtained in August were found to Le para- 
sitised to a certain extent by several different insects as well 
as by a fungus. 
(1) A small hymenopterous grub was watched feeding as an 
external parasite on one of the full-grown larvae. The cater-
