much difference in the colour, &c, of the specimens of the moth, not sufficient 

 at least to warrant me in asserting there is more than one species. Some of 

 the larvae are bluish instead of olive green, and some have black heads, while 

 others have green ones. In all cases the spots are black. 



From oak and hornbeam we may beat the larvse of the pretty Tortrix viri- 

 dana as well as those of Catoptria fulvana and Tortrix xylosteana. Yiridana 

 is green (rather yellowish behind), with black head and minute spots ; fulvana 

 is green, with a rough brown head, darker green on the back and spotted 

 with black ; xylosteana is of a dull olive colour, spotted with white, each spot 

 having a minute black dot in the centre, and its head is black, fulvana 

 feeds on bramble as well as oak, and xylosteana may also be found on honey- 

 suckle. They are all three generally distributed and more or less common. 



The pale yellow black-headed larvse of Hypermcecia angustana may be 

 beaten from sallows and willow : it lives between united leaves. In the 

 southern parts of England the red brown, black-headed and black-spotted 

 Penthina salicana folds over willow leaves ; and the bright green Penthina 

 caprcena lives in the sallow shoots, which should be collected by those desir- 

 ing to breed this moth, 



The dull olive green Penthina cynoshana feeds on plum, hawthorn, sloe, 

 and some other trees : the head, second segment, and spots are black. The 

 green pale-headed Tortrix corylana may be beaten out of hazel and also dog- 

 wood, and that of Penthina betulcetana from birch. The generally common 

 Tortrix costana may be found by searching marsh-growing plants ; it is a 

 dull looking dark brown larva, with a black head. 



On nettles, my readers are sure to find abundantly, the larvse of Sericoris 

 urticana ; and on rose those of Dictyopteryx Bergnianniana, it is a yellowish- 

 looking pale green larvae, with a black head, and second segment of the same 

 colour. Pardia tripunctana is also very abundant in the early part of the 

 month, on both cultivated and wild roses ; it is reddish brown in colour with 

 a black head. Eose shoots should also be collected now by those desiring of 

 breeding Spilonota roborana. 



My readers are sure to notice that, in May, the elm leaves are fastened to- 

 gether by some pale olive-green black-headed and black-spotted larvse. 

 These produce Grapholita trimaculana, a species which we find everywhere in 

 abundance. They are easily reared and it will be well to collect them in large 

 numbers, as interesting varieties of the moth, are very likely to be obtained. 

 It comes out in June, and I will notice it more particularly next month. 



The generally distributed dull brownish larva of Relinia buoliana, feeds in 

 May, in the shoots of Scotch fir-trees. It has a black head and the second 

 segment is also black* There are some other tortrix larvse occurring about
