\1Q [October, 
I potted for it a small plant of Convolvulus arvensis, and on two little shoots of 
this, bearing in all not more than five or six very small leaves, it fed and grew and 
moulted contentedly during the first half of its fifty days' life, its longest joui-ney 
all that time not exceeding an inch and a half 
Had the other eggs escaped squashing on their journey, probably I might hav^ 
had the pleasure of seeing both the varieties which Hiibner figures, but the 
green one yet remains a desideratum ; my single larva was his brown variety. 
When first hatched, it was a dingy-grey little looper, with a black transverse 
dorsal hump on each of the four middle segments ; but at each moult these humps 
became less, till at last there remained nothing but the usual dorsal dots, black 
and distinct, and these too afterwards disappeared. When full-grown the larva is 
about an inch long ; the legs twelve ; the body cylindrical, thickest at the fourth 
segment ; the segmental divisions deeply indented ; when at rest the middle 
segments are generally arched, and the head bent down. The colour a rich choco- 
late-brown ; dorsal line rather darker, and edged with very fine paler lines ; sub- 
dorsal line also darker, but scarcely visible ; spiracular stripe broad, of a pale 
yellow, and with a fine brown thread running throughout its length, immediately 
after the last moult ; there were some rich yellow and orange spots also in it, but 
these disappeared, and the whole stripe grew paler. — Id. 
Note on Cucullia scrophularice and verbasci. — In the following notes I hope to 
be of some service to those who, like myself, have entertained doubts concerning 
the real distinctness of the two species, from inability to distinguish the larvse 
found feeding on Scrophularia aquatica and nodosa from others on Verhascum 
thapsiis and nigrum,. It is therefore with great pleasure I acknowledge my 
obligations to Mr. Doubleday, by whose kindness I am at length made acquainted 
with the real scrophularia^; in four fine larvge he presented me with on the 4th and 
8th of last July, feeding on flowers and seed-vessels of Scrophularia nodosa, the 
sight of which immediately dispelled all my previous doubts, as it did also any 
existing in the minds of Mr. Hellins and Mr. D'Orville, through whose hands they 
passed to mine ; the latter gentleman having for years had great experience in, and 
devoted much attention to, this particular genus in their larval state. 
The larva of scrophularice, when full-grown, is 1| inches in length, plump, and 
cylindrical ; the head rounded, and a trifle smaller than the 2nd segment. Viewed 
sideways, it appears of uniforin thickness ; but seen on the back, it tapers behind 
fron^ the 10th to the anal segment. 
In looking on the back, its most valuable character, by which it can be 
instantly identified, is apparent in the bright yellow dorsal mark ; for whether 
little or much intersected by black, it is distinctly seen to be a blunt-pointed tri- 
angle of yellow, close to the beginning of each segment, pointing forwards, its 
transverse base being longer than the sides, placed on rather less than the first 
half of each segment. The ground colour in front of the two sides of the triangle, 
with belly and prolegs, is whitish-grey, or pale blueish-grey, or greenish-white ; but 
the broad space behind the base of the triangle is a bright full green, varying indi- 
Ti'dnally towards blueish-green or grass-green. Thus it will be seen there is a 
broad green band across the end of each segment. The black marks on the back
