POLYCHROSIS ACANTHIS, MEYR. MS. (PLATE LX 
Larvee were found at Pusa on 26th November 1919, boring in stems of 
Justicia gendarussa. The larva bores at the top of the stem, which it usually 
enters at the axils of the leaves or branches, causing the top-shoot to wither. 
(Plate LX, fig. a.) The bored shoot breaks very easily at the place where | 
the larva enters it. The larval tunnel usually runs along the axis of the stem, 
but may extend across it. Pupation takes place inside the bored stem in 
which the larva prepares a hole of exit for the future moth, the pupa 
wriggling out of the stem to some extent before the moth emerges, 
The full-grown larva (Plate LX, fig. 6) is about 8 to 10 mm. long. 
sub-cylindrical, moderately stout, tapering very slightly posteriorly, pale- 
yellow slightly tinged with green ; head large, shiny, dark-brown, almost b!ack ; 
prothoracic shield concolorous with head ; legs pale-yellow tinged with grey ; 
five pairs of equally-developed short prolegs concolorous with body. 
The pupa (Plate LX, fig. c) is about 4:5 mm. long, yellow ; head 
with a small anterior snout-like process ; abdominal segments anteriorly with a 
transverse dorsal row of posteriorly-directed spines and posteriorly with a 
similar but rather indistinct row of much smaller spines ; anal extremity rather 
rounded and provided with a few circinate hairs. 
Moths (Plate LX, fig. d) emerged on 8th and 15th December 1919.

LOBESIA “ABOLOPA, MEYR. (ante, page 5%) (PLATE LXI, FIG. 1.) 
This has also been reared at Pusa from larve collected on 11th September 
1919 living and feeding in the calyces of flowers of gumma (Leucas carata). 
The larva (Plate LXI, fig. 1 a) is about 8 mm. long and 1 mm. across the 
middle, tapering slightly posteriorly, green with a yellowish tinge ; head shiny 
black ; prothoracic shield black, divided medially ; prothoracic legs black, 
others greenish-yellow. 
Pupation takes place within a thinly-built cocoon hidden amongst the 
ealyx of the flower or sometimes placed inside a tubular floret. The pupa 
(Plate LXI, fig. 16) is about 4:5 mm. long and 1:5 across mid-body, dark 
rown with a greenish tinge. The moth (Plate LXI, fig. lc) emerges 
after a pupal period of about seven days. (Pusa Insectary Cage-slip 1916.) 
ARGYROPLOCE APROBOLA, MEYR. (anie, page 57.) 
This has since been reared at Pusa from larve found on 16th October 
1919, hiding among rose-petals and feeding on them ; as the larve spin silk 
the petals do not fall off although they are cut basally. The larve are sensitive
