116 NEW ENIGMAS FOR SOLUTION. 



totally different from that of C. Laburnella, that it is cannot 

 be that species ; should the insect prove distinct the name of 

 C. Wailesella has been suggested for it. Mr. Weir bred a 

 Cemiostoma some years ago from the Genista tinctoria; 

 but inexperienced as we then were with regard to the habits 

 of the larva, and there being no apparent difference in the 

 perfect insect from Spartifoliella, the subject dropped and 

 had got lost sight of. 



35. A Coleophora larva, feeding on the leaves of thistle, 

 has been collected in September by Mr. Gorham and Mr. 

 Aris. The case is long and whitish. Can this be C. 

 therinella ? 



36. A Tischeria larva which makes a brownish blotch 

 with distinct concentric rings, on oak leaves, very different 

 from the uniform white blotches of T. complanella ; these 

 were very abundant at Abbey Wood and at West Wickham 

 Wood in September ; indeed they seem nearly as plentiful, 

 though not so conspicuous, as those of T. complanella. 



37. A Coleophora larva, found on birch in a case which, 

 though somewhat resembling the case of C. viminetella, is 

 more globose and has more the appearance of a birch-bud ; 

 the blotch it makes in the leaf is of a peculiar brown, like 

 the blotches of C. limosipennella. I found one of these at 

 West Wickham, October 31st. 



38. A Lithocolletis, mining the upperside of beech-leaves : 

 of this mine I found two examples on one leaf at Alton 

 Towers, at the end of July. Professor Frey met with this 

 two years ago, and this autumn has obtained ten specimens 

 of the larva.
