THE entomologist’s RECORD. 
of the egg-shell and the body coiled round, with the back 
against the circumference. All the eggs hatched (on three 
consecutive days) between 9 and 11.30 a.m. I think this is a 
favourite hour iox Acronycta eggs to hatch, but it can hardly be 
so pronounced in other species as here, or I should, I think, 
have made some observations on the subject in some instance 
or other (Egg, PI. VIII., fig. 7). 
The young larva, when hatched, eats up the dome of the 
egg-shell, unless disturbed, leaving the base fixed to its attach- 
ment. Like most of the others, this larva also likes to eat its 
moulted skin, and invariably does so after each moult, yet I 
have rarely seen this actually being done, the evidence usually 
being the disappearance of the cast skin, except a few frag- 
ments. I do not know on which side of the leaf the egg is 
laid. In the wild state, it is certainly laid solitarily, in Cus- 
pidian fashion. 
The following are the notes taken this year of the larva of 
strigosa. [I see I make some confusion as to the 2nd segment 
being pale or dark, really it is pale, but the plate takes sufficient 
colouring to rank it with the dark segments on a superficial 
viewj (Newly hatched larva, PI. IX., fig. i). 
July 1 2th, i8gi. — One moth of strigosa received by post 
from Mr. W. Farren. July 13th. — Has laid 24 eggs on glass. 
July 14th. — Has laid 6 more eggs, those first laid already show 
a' slight coil, and are very transparent. July 21st. — Of the 
eggs noticed on the 13th the first hatched at g a.m. At i p.m. 
all hatched but two, of which one was addled. The young 
larvae eat the whole of the upper dome of egg-shell. They are 
very flimsy and transparent, with hairs nearly half their own 
length (length of larva about i*6 mm.) ; the dark segments 
have some brownish tinting dorsally. The dark segments are 
4.5, 8.g and 12, the pale 2.3, 6.7, 10. ii, 13 and 14, and hairs 
pale, finely serrated or spicated as are those of tridens and 
others. Hairs in ii about two-fifth length of others and 
proportionally fine and tubercles less marked. Psi and 
tridens are really very delicate little larvae at this stage, and 
strigosa only differs in degree, but is much more delicate in 
appearance. Head tinted with indigo, looks dark to the naked 
eye. July 22nd. — Larvae rest underneath the leaf, but will 
take the upper surface when the leaf is upside down, they sit 
curled in horseshoe shape and eat holes into the leaf, but not 
through the upper cuticle, the holes being placed irregularly 
round the larva. July 25th. — When full-grown, in this (ist)
