jB. spinosissima, and other roses, drawing and twisting the leaves 

 tightly together, and eating out the heart. In gardens it is a great 

 nuisance, eating out the inside of the young flower-buds directly they 

 appear. It is rather later than rostBcolana, feeding through June. 

 When full-fed it leaves the shoot or bud to spin up among leaves or 

 rubbish, where it becomes a light brown pupa. The moth emerges 

 from the middle of July. It is rather variable, apparently influenced 

 by food, since specimens reared on Rosa spinosissima, besides being 

 small, are generally more or less suffused with rosy or grey. 



Spilo7iota trimaculana, Haw. (suffusann, 7i.^. Larva very short 

 and obese, tapering from near the middle. When half grown dark 

 livei'-coloured, with short, transparent, glistening hairs, and shining 

 black head and plates. When full grown paler in colour, aiid tinged 

 with greenish-brown, sometimes yellowish beneath, head light brown, 

 dorsal plate black, anal plate yellowish. In young shoots of hawthorn, 

 drawing the leaves slightly together and eating out the heart. Rather 

 difiicult to find, as it generally chooses a strong terminal shoot rather 

 high on the hedge, and does not greatly distort it, but merely checks 

 its growth. Moving readily from shoot to shoot, but leaving them 

 when full-fed to spin up among rubbish, where it becomes a light 

 brown pupa. I found well-grown larvae from April 27th to the middle 

 of May. The first moth emerged on June 3rd. 



Spilonota incarnatana, Hb. {amcenana, Hb.). I have searched for 

 the larva of this species in its locality the last two seasons, without 

 success (the larvae found all producing rohorana), and have been dis- 

 appointed of the opportunity of describing it, but Mr. Hodgkinson 

 tells me that he rears it from larvae which are not distinguishable from 

 those of rohorana, feeding on Hosa spinosissima, in "Lancashire. This 

 agrees with Dr. Hofmann's description from Treitschke : " Very 

 similar to rohorana, but smaller, pupa light brown with darker wing- 

 cases." According to Ottmar Hofmann, it feeds also on Rosa canina 

 and hircli. If correct, this must refer to the large inland variety which 

 is found occasionally in Epping Forest and other southern localities. 



While, therefore, the larvae of these last three species are so much 

 alike as to be barely distinguishable, that of roscecolana differs from 

 them strikingly in form as well as in colour, a distinction the more 

 interesting as it accompanies a striking difference in shape in the fore- 

 wings of the pei'fect insect. 



Notocelia JJdmanniana, L. The larva of this species is very well 

 known, and has several times been described, and I only mention it to
