yellowish colour, whereas the segments themselves have become of a darker 
ereenish-yellow. 
“ Second instar. About 2 mm. long and rather stout. Colour a greenish- 
yellow, paler below and on the sides on which the spiracles ‘stand out darkly ; 
there are apparently small latero-dorsal tubercles which bear rather long white 
clubbed hairs. 
“Tf feeds on the glandular petioles, biting through the base and drawing 
the stalk into its mouth by a series of movements and finishing by devouring 
the drop of gum. It seems fairly voracious, but is evidently rather fastidious 
in its selection of the glandular hairs. 
“Third (2 antepenuliimate) instar. About 3 mm. long and fairly stout. 
Colour a pale green with interrupted pinkish latero-dorsal, lateral and supra- 
spiracular stripes. Tubercles green at base, brownish at points of emission 
of the white hairs....... 
“ Fourth (ultimate) instar. A fully-fed larva on the point of pupation is 
just over 7 mm. long, moderately stout, stoutest about middle of body, tapering 
rather more rapidly towards the head. Colour pale green, a dark rather reddish 
narrow medio-dorsal stripe ; latero-dorsal tubercles red and surrounded with 
dark red dashes, which assume a rather longitudinal direction, so that the larva 
seems to have an interrupted rather broad latero-dorsal stripe. Head pale 
green with dark ocellar marks on either side. Jaws and mouth-parts reddish. 
Long palps on either side of jaws. 
“The larve, however, vary much, but seem divisible into three types :— 
(1) Pale green with a distinctly reddish tinge ; a narrow darker green 
dorsal stripe bordered on either side by a pale yellowish longitudinal line ; 
head pale green with dark reddish ocellar patches ; tubercles reddish-brown ; 
hairs white, as long as diameter of segmental interstices, slightly and regularly 
dilated towards apex ; prolegs pale green, almost transparent. 
“ (2) Paler green, on which the tubercles show up conspicuously as a bright 
dark red. | 
(3) Very much suffused with red, so as to appear of almost as red a colour 
as the Drosera itself. ? 
“The intensity of the dorsal stripe is very variable ; in some specimens 
it is very distinct, in others quite obsvlete. 
“In its final instar the larva shows a decided preference for the buds and 
seeds of the Drosera, eating a hole in the side of the seed capsule and devouring 
the contents, but it:also eats the leaves. 
“ General remarks on the larval state. In all its stages the larva is extremely 
similar to the Drosera and difficult to distinguish. Even a full-grown larva
