November. The lac in which the larvse of Enhlemma amabalis were 
found was that produced by the July brood. I first noticed the attacks 
on the 26th September and collected some of the larvae. The larva 
is white and unmarked, the head only being dark. It appears to feed 
upon the soft bodies of the lac larvae, taking up its abode with them 
beneath their resinous coating and forming a webbed covering con- 
nected with the outer air by a silken tube woven together with an ad- 
mixture of reddish excreta. Whether the tube is formed just previous 
to pupation, as a tunnel of escape for the perfect insect, I am not aware. 
Mr. G. C. Dudgeon, F.E.S., of Palampur, Punjab, to whom I am in- 
debted for the naming of the insect and to whom I sent specimens of 
the larvae, perfect insect, and a specimen branch of the lac incrustation 
attacked by the larvae of E. amabalis, is of opinion that these silk tubes 
are made as a timnel of escape, as the tubes are all of the same size and 
therefore presumably formed by larvae in the same stage of development ; 
and portions of the pupa shell were found inside the resinous coating just 
beneath these tubes. On the other hand, I did not notice that these 
tubes were ruptured by the emergence of the perfect insect. Figs. 
2, 2a show these tubes. 
“ Six imagoes of the larvae which I collected early in November 1899 
emerged between January 12th and 20th, 1900. Three more between 
January 22nd and 27th and two more on February 17th. It would 
appear, therefore, that one generation of the insect lasts about seven 
months as the lac incrustation only begins to form in August. 
“ Among the more interesting points requiring investigation with 
regard to E. amabalis I may mention the following in the hope that 
they may bring forth some information from other quarters : — 
“ (1) Does E. amabalis attack both crops of lac ? (So far I have 
only found it on the winter crop.) 
“ (2) Does it attack lac on trees other than Zizyphus xylopyra ? 
“(3) How many generations of the insect are there in the year ? (There 
must surely be more than one, because the interval between January, 
when the imagoes emerged, and August, when the winter crop on which 
I foimd the larvae commences to form, is unaccounted for.) 
“(4) The eggs, their form, colour, etc., and where they are deposited.” 
I have since bred out moths of this species in Dehra Dun from lac 
received on S. trijuga from Eaipur in the Central Provinces. Moths 
issued in the last week in March, the delay in appearance being account- 
able for by the much colder chmate.
