reposes in a fine cocoon. There appears also to be a summer brood, 

 but certainly the spring brood has, in the preceding autumn, the most 

 abundant supply of larvae. 



6. L. pomifoliella, Tisch. I met with this in the pupa state in Oc- 

 tober, 1848 and 1849, on scattered bushes of Primus communis and 

 orchard trees of all kinds. From these I obtained specimens in Janu- 

 ary. In the open air the species flies uncommonly early ; I found a 

 beautiful specimen, a variety, as early as the 7th of May at Polchow. 

 At the end of July the summer brood is to be found in all the three 

 stages of larva, pupa and imago at the same time. It is not exactly 

 very abundant. 



Note 1. — Not only the following species, L. pomonella, but this 

 also, furnishes many difficulties. Here is an example : — I found on 

 whitethorn, at the end of September, a larva which was quite differ- 

 ent from the accurately observed larva of L. pomifoliella, yet the moth 

 differs in nothing but a deeper ground colour from an ordinary L. po- 

 mifoliella. 



The mined abode is narrow and rather short; it lies on the edge of 

 the leaf, and runs between two side ribs, somewhat into the heart of 

 the leaf. The lower (loosened) skin of the leaf is dirty brown, laid in 

 several irregular folds, (generally it is pale green) ; on the upper side 

 there is nothing peculiar about the abode. At the marginal end of it 

 the larva collects its excrement into a little heap. The larva itself is 

 hardly so large as is usual in Pomifoliella ; the very distinctly heart- 

 shaped head is quite black, polished, and proportionally larger than 

 in other more considerable species. The colour is dirty white, on the 

 two or three last segments clearer. On the first segment is a broad 

 but short spot, which is black, shining, and divided lengthwise in the 

 middle, similar in form to the spot on the first segment of the larva of 

 L. connexella. The back is brownish, from the food showing through. 

 On the under side there is nothing extraordinary, except the perfectly 

 black legs. 



On the other hand, I have described the larva of the ordinary Po- 

 mifoliella from orchard trees, as follows : — 



Larva thin, pure citron-yellow, anteriorly clearer; the incisions be- 

 neath are a little darker ; head likewise only a little darker than the 

 colour of the skin, legs paler. The second and third rings are scarcely 

 broader than the rest of the body ; at the anus the larva is more 

 rounded than pointed. On the seventh and eighth segments is a pale 

 brown, roundish spot, it is not sharply defined, and is marked with 

 darker dots in the middle, the division of the segments does not
