Larva. 



The larva has already been described in detail by Milliere (see 

 Bankes " Ent. Mo. Mag.," xlii, p. 6) ; but for all practical purposes 

 one may regard it as a very ordinary-looking green Tortrix larva, 

 with a number of stiff, whitish hairs on its body ; head glabrous, 

 and of a shade somewhat yellower than the body. On the Conti- 

 nent it is said to feed on a great number of different food plants ; 

 but here, as in Guernsey, it has taken kindly to the Euonymus of 

 our gardens, Euonymus japonic us, I believe, uniting the two fully- 

 developed terminal leaves, and feeding on the tender shoot thus 

 enclosed between them, apparently, if we may judge by the number 

 of empty domiciles found, shifting from one shoot to another as 

 soon as the food-supply in the first is exhausted. 



Pupa. 



The pupa is fairly robust, dark (blackish) brown, with a slightly 

 lustrous appearance, and measures from 9 mm. to 10 mm. in length. 

 It is enclosed in a dense, silken web between the last pair of leaves 

 in which the larva has fed. When the imago is ready to emerge, the 

 pupa pushes itself up through the top of the web, by means of 

 the anal hooks with which it is furnished, and protrudes about half 

 its length. 



Ovum. 



I have no personal knowledge of the ovum, but the Rev. F. E. 

 Lowe tells us " the eggs make a bright, triangular-shaped patch of 

 vivid green, almost exactly the colour of the brighter tints of this 

 evergreen " (Euonymus). 



Time of Appearance. 



On the shores of the Mediterranean, where the species appears 

 to have its home, it is on the wing from the middle of February to 

 the end of April, and Milliere tells us that he doubts whether the 

 insect has more than one brood even in the South of France. He, 

 however, says that the larva hatches out about the end of November, 

 grows slowly during the winter, and becomes full fed in February. 

 Tutt, on the other hand, says distinctly, " it is double-brooded in the 

 South of France" ("Ent. Rec," xvii, p. 343). Lowe tells us that 

 in Guernsey it " makes its appearance at the extreme end of August, 

 and continues up to the end of the first week in October — weather 

 permitting." With regard to Britain, the earliest date we have — 

 assuming that the insect which I saw at Eastbourne was really this 

 species — is September 9th ; the original British specimen was taken 

 at the end of September or beginning of October, and the Bognor 

 example on October 23rd. Of the specimens bred the first emerged
