remains uniform throughout. The pupa is thickish with blunt

Moth.— Head very small.and antenne minutely ciliated in 
male. Head and thorax greyish red-brown; abdomen black- 
brown with orange segmental bands. General colouring of

black-brown with orange and scarlet blotches, Fore-wing 
greyish red-brown, irrorated with a few dark specks. Hind- 
wing black-brown, with a curved orange band with scarlet edges 
from upper angle of cell to near anal angle; a band on the 
margin from vein 2 to anal angle. Underside of fore-wing 
black, with orange fascia in cell and far beyond it; the costa 
and apex pale brownish with dark specks; the inner margin 
yellow. Hind-wing pale brownish with dark specks ; orange 
towards anal angle, with two large black spots. 
Expanse of wing 32—40 millim. Fig. 71 in Jajurious 
Insects shows the larval, pupal and imago stages of this moth. 
Life History. 
This insect, whose larve defoliate the teak tree, passes 
through a large number of generations in the year, the number 
at times reaching seven life cycles according to Mr. T. R. D. 
Bell. It thus resembles in this respect its companion Pyrausta 
macherailts with whom itis generally found on the trees. The 
time of appearance of the larve is not fixed in any way, as 
there is a continuous series of generations as long as the leaves 
remain upon the trees. It is probable that these generations 
overlap to a certain extent, but I do not know whether this 
is so marked as in the case of the Pyrausta. 
The larval stage lasts about 19 days and the pupal from 8 to 
11. These periods will of course vary in different parts of the 
continent, and on the Bombay side it is considered that from 
egg to moth takes about six weeks. 
The stage in which the insect passes through the winter has 
not yet been observed, but the first larvae make their appear- 
ance in South India, and probably also on the Bombay side, in 
April-May, this being the period at which they are also first
