242 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 g and 11.30 a.m. I think this is a 

 favourite hour (or 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, PL 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 I2th, i8gi. — One moth of sfrigosa received b}^ 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, lo.ii, 13 and 14, and hairs 

 pale, finely serrated or spicated as are those of tridcns and 

 others. Hairs in 11 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)
