I12 (February, 
In colour, the head is a pale transparent yellowish-green : the dorsal stripe of 
opaque pale blue-green, or whitish blue-green, has, by degrees, become wonderfully 
developed, and is now so broad as to occupy nearly the whole area of the back, © 
there being but a mere line of the previous transparent deep yellowish-green left 
next the sub-dorsal white stripes, which, on the twelfth segment, have a tendency | 
upwards to a point, as though inclined to meet one another there, but return again © 
to their former level, and nearly meet at the end of the anal flap ; the sides are of 
avery pale and delicate opaque whitish blue-green, with two fine rather wavy 
looking white lines nearly parallel along the region of the spiracles; the ventral 
surface, legs, and pro-legs are of a glossy pale full green; the tubercular warts are 
now hardly to be observed on the level smoothness of the back; though the 
colouring is nearly all opaque and approaching more or less to whiteness, yet the 
surface of the skin is by no means rough, but has a certain faint polish, allied to 
smoothness, like that of a new white kid glove. 
When about to pupate the larva loses all its beautiful opaque colouring, and 
then becomes of an uniform green, and semi-transparent, otherwise like the under- 
side of a maple leaf in tint. 
The pupa is enclosed in a thin brittle earthen cocoon, of a broad, oblong oval 
shape, and formed in an upright position, with little silk in its texture, though the 
interior is very smooth; the pupa itself is of a more slender form, with the abdomen 
somewhat more tapering than that of most Notodontide, though both extremities 
are rounded, the tail being furnished with a pair of very small, fine, curved spikes, 
with which it is attached to the summit of the cocoon, the pupa skin is delicately 
thin, polished, and of a purplish-brown colour, whilst containing the future moth. 
It should be mentioned that the larve will feed on sycamore, as well as on | 
maple, and also, that when young, and even half-grown, they seem to be social, as 
two are often found reposing on the under-part of a maple leaf, folded round side 
by side, like a schoolboy’s pot-hooks. 
The perfect insect appears in October and November.—Wm. BuckiER, Ems- 
worth, December 13th, 1870. 
Leucania vitellina at Torquay.—A specimen of this species, in good condition, 
has been sent to me from Torquay for identification, with the information that it 
was captured with another specimen, on November 5, 1870, at ivy flowers. 
One was taken also on November 3rd, 1869, at Arbutus flowers, and another 
late in October, 1868, at ivy. These dates seem later than those previously 
recorded, but the moth sent to me has all its fringes perfect, as though it had not | 
long been on the wing.—J. HELuins, Exeter, 9th January, 1871. 
Triphena subdsequa in Gloucestershire.—I find, amongst my captures at sugar 
last season, a very perfect specimen of the above insect. I record its capture for | 
the following reason: I had never seen a specimen of this insect ; but, wanting a | 
single Orbona, to replace a damaged one in my cabinet, I took four amongst some 
twenty or so at sugar one evening, the brightest and perfect looking of the lot. It 
was set and put by in the store box. When I came at the end of the season to 
arrange my captures, the damaged Orbona was taken out and the new capture put 
in its place. Although I had never seen subsequa, I sawat once that the new moth
