320 4 FURTHER NOTE CN MONOPHLEBUS STEBBINGI. 

egg cases were those of the eggs of last year from which the 
males of this year had developed, and that the males hibernate 
through the rains and portion of the winter in the egg stage. 
Beneath this tree, under the rough flakes of bark, a number 
of newly-deposited egg clusters were also found. 
I have not yet found the insect which develops from these, or 
from portions of these, egg clusters, z.e., the insect which forms the 
second stage (if there is one) in the life history of this 
monophlebus. , 
I have said that the conspicuous white female scales dis- 
appear from the forests about the beginning or middle of May; 
the exact time depending upon the nature of the weather exe 
perienced during the winter. Mr. Milward has noticed, however, 
that it is generally possible to find a few specimens right on into 
September. This year, when the attack was practically over, on 
May 7th and later dates, I found in several places some young 
scales, canary yellow to brown in colour and from ;4,th to 4th” 
in length, in fact in the stage and age of those usually found in 
February. They were clustered thickly on the new shoots of 
some sal trees and on the top shoots of some sal saplings and 
sal and koura coppice. 
As compared with the previous year, the scale matured at a 
much earlier date during 1902, the insect being at least a month 
earlier in all itsstages of development. This was undoubtedly 
due to the fact that the winter was a very dry and rainless 
one, and consequently the young scales did not perish in the 
large numbers which a rigorous winter must usually kill off. 
Until its third moult, itincreasedin size apparently unchecked, 
and was found throughout the Dun and Saharanpur forests in 
enormous numbers. By the time it is ready to undergo its third 
moult, it being then about half-grown, it has left:the leaves and 
small twigs and descended to the larger cortex-covered 
branches, and throughout the attacked areas these branches 
were encircled with long rows of the white cast papery skins 
of the third moult, which remained gummed to the branches by 
the thick sugary secretion given out by the insects. These 
rows corresponded to the position the insects take in feeding, 
collecting in clusters all down the stems. Pl. XIX, fig. 4, e,
