joint author of Kirby and Spence’s ‘ In- 
troduction to Entomology.’ Mr. Spence 
expired on the 6th inst., at his residence, 
No. 18, Lower Seymour Street, Portman 
Square, aged seventy-seven. Though of 
late years, owing to his increasing deaf- 
ness, Mr.Spence abstained from attending 
the social reunions of entomologists, his 
interest in his favourite Science continued 
unabated to the last, and his loss will 
long be felt by all who had the pleasure 
of his acquaintance.

13Y Q. 
(Concluded from p. 119.) 
O. M. Unangulata. Of this species I 
have seen five or six broods, and have so 
far found the larva not to vary very 
much. In shape it tapers slightly to- 
wards the head : the ground is of a pale 
stone-colour ; there is no regular dorsal 
line, but a series of dusky dashes and 
dots, and at the five middle segmental 
divisions these dots become enlarged and 
quite black in colour, and are preceded 
by an oblong transverse reddish mark, 
and that again by a square white spot ; 
there are two very wavy and diffused 
subdorsal lines of a very faint dusky 
black, but just above the spiracles is a 
pretty clear thin line of the ground- 
colour, followed by another of the darker 
tint ; the spiracles are black ; the belly of 
the ground-colour only more yellowish, 
and marked on each side at the five 
middle segmental divisions with little 
groups of fine black dashes and dots. It 
thrives well on chickweed ( Alsine media), 
being full fed in somewhat less than a 
mouth. Whether the moth appears again 
out-of-doors in the autumn I cannot say, 
but I bred two or three in my flower-pot 
about the 20th of August, in the same 
way autumnal specimens of Melanippe 
Itivata and Anliclea Rubidata have been 
bred in-doors, though I have never seen 
them on the wing out-of-doors at that 
time. 
0. M. Fluctuata. One day in July I 
found, together with six or seven of the 
(to me common) brown and grey variety 
of this larva, one that was quite green all 
over, but with sufficient indications of the 
dorsal pattern to make me think it was 
of the same species, as in time it proved 
to be; I mentioned the circumstance to 
one of our great men, and was informed 
that he had never seen any but green 
larvae of M. Fluctuata ; this set me 
breeding all I could, but out of six or 
seven broods — certainly not large ones — 
I succeeded in obtaining but one green 
larva, which on passing its last moult 
appeared with a dorsal line of two tints 
of red, but grew gradually less brilliant, 
until just before spinuing it showed no 
red at all. 
O. Camptogramma Fluviata. The fol- 
lowing dates may prove of interest:— a 
female laid me a batch of eggs on the 
27th of July, from which I bred the 
moths from the 1st to the 10th of Sep- 
tember ; all their transformations having 
been passed in an average time of forty 
days. On the 22nd of August I procured 
eggs from another female, the moths 
from which appeared from the 8tli to the 
11th of October, having thus taken on 
au average seven or eight days more 
than the former brood to go through 
their changes. Since then I have been 
told of a brood batched iu October, which 
passed six weeks in the larva state alone, 
and from which at the time I am writing 
(December 9th) no perfect insects have 
yet appeared ; also of another brood of 
larva, hatched in November, which are 
still very small, and feeding but slowly. 
Most of the captured specimens of the 
moth itself that have come under my 
notice have occurred near low ground, 
but I cannot think it an exclusively
