it widens out into a lozenge shape, contracting again to a narrow stripe on the 
twelfth and thirteenth : the tubercles show paler than the rest of ground, because 
the brown hairs on them, being divergent, allow more of the paler skin to be seen. 
Just below the second row of tubercles comes the sub-dorsal line, which in fact is 
composed of a series of dark drown dashes, one on each segment, sloping back- 
wards and downwards, so as to let the tubercle stand out in high relief; along the 
edge of the lateral ridge runs a whitish stripe, which is continued round the anal 
extremity ; the belly and legs of same colour as the back. The whole skin is studded 
with short bristles of a dark brown colour; the head is black and polished, but with 
a streak above the mouth, and also the base of the papillz, yellow. 
After this there is no change in appearance, save that of growing paler and 
‘more unicolurous (perhaps, as the bulk increases, more of the paler skin shows 
between the dark bristles), until some specimens are of an ordinary flesh tint, and 
others of a brownish-flesh colour, and at this point the larve assimilate well with 
the changing of the corolla of their food-plant. After they cease feeding, they 
turn off to a faint greenish-yellow. 
When full-grown the larva is about one-third of an inch long, and may be 
roughly compared to a moderately-sized grain of wheat cut iv half, the back 
being arched in a curve, and the belly flat with the legs placed well under it; 
or it may be compared to a very tiny tortoise, the head being very small and re- 
tractile, and a lateral ridge running all round, and giving the appearance of an 
upper shell; the second segment is the longest, and has a sort of triangular plate 
on its middle, and the last three segments are slightly depressed ; the inner rows 
of dorsal tubercles are rather projecting, and thus form between them a sort of 
dorsal hollow, and the second row I have already mentioned as affecting the sub- 
dorsal line.—Joun Hetins, Exeter, 9th November, 1870. 
Some notes on the young larva of Deilephila galii.My observations on the 
early stages (unfortunately confined to the first three stages) of D. galit rather 
differ from Mr. Buckler’s. On the 9th September, 1870, my friend Dr. Buchanan 
White gave me a very small larva, as that of stellatarwm, found in Kirkeudbright- 
shire, on the borders of the Solway Firth: it was then about five lines in length; 
ground cclour dark green, with a broad sub-dorsal line and a sub-spiracular nar- 
row line white, and the horn, rough, straight, black. It moulted without difficulty, 
about a fortnight after I got it, and emerged greatly changed in appearance. 
Its length now was one inch two lines; ground colour entirely black ; no dorsal 
line, sub-dorsal line white and very narrow, and strung on to it a row of ten large 
lemon-yellow spots with orange centres ; sides sprinkled with minute white dots, 
avery narrow sub-spiracular line interrupted at each segment ; three rather marked 
transverse raised lines on each segment; horn rough, straight, black. 
This garb only lasted about twelve days, when it took to the muslin cover of 
its prison, and there remained without moving for five or six days, finally moulting 
onthe 6th October, with evident discomfort: and it was merely by keeping it 
quite warm and in the sun that I could persuade it to eat after this moult. 
Jt was now one inch eight lines in length; ground colour black, with the 
head, plate on second segment, and anal flap bright red-brown (the red-brown 
gradually toned down to dark brown) ; no dorsal line, no sub-dorsal line, only the
