194 THE ENTOMOLOGIST. 
With the exception of a lateral fold below the spiracles the 
skin appears to be smooth and without warts. The ground 
colour of both the head and the body is whitish green; the 
former is margined with black; the latter is marked with 
black spots, consisting of, first, a medio-dorsal series, con- 
taining one in the middle of each segment, and a smaller one 
at each division ; secondly, a sub-dorsal series of linear spots 
on each segment; and lastly, a rather oblique one on the 
skinfold at the anterior end of each segment: all these black 
spots are larger on the middle segments. Spiracles incon- 
spicuous:—H,. J. Channon; Woodlands, Lewisham, July

Description of the Larva of Emmelesia decolorata.— 
As the larva of Emmelesia decolorata is not described 
either in ‘British Moths’ or in the ‘Manual, you may, 
perhaps, think it worth while to give your readers the 
following notes on this insect:—It is a fat, sluggish 
larva, resembling in outline some of the Eupithecie 
(Pulchellata and Linariata, e.g.), and when resting, ex- 
posed on the plant, is stretched out with the head rather 
thrown back. In colour it reminds one of the larva of 
Ephestia elutella. The head is small, of a shining brown 
colour, and evidently two lobed. On the 2nd segment there 
is a horny brown plate, and the anal segment, the claspers 
of which are wide and spreading, is similarly protected. The 
medio-dorsal line or band is broad and distinct, but tapering 
to each extremity, and is of a pale colour. The dorsal area 
is dull, faint reddish, and has a few shining hairs. On the 
sides the skin seems to be gathered up into a ridge, the 
summit of which is the palest part of the larva, and forms a 
nearly white, irregular, lateral stripe. Below this the reddish 
colour appears again as an irregular line, abruptly marking off 
the central area, which is pale, and has several small, but 
distinct, spots of a pale brown colour on each segment. I 
have generally found the larva on the stameniferous plant of 
the white campion, although it sometimes feeds within the 
seed-capsule. Its presence is generally first noticed by the 
half-eaten petals, although its food is not confined to these. 
It will eat either petals, or calyx, or seeds ; but it is generally 
found within the calyx of the unopened flower-bud, devouring 
the contents. Later on, however, it enters the seed-capsule,
