NEW BRITISH SPECIES IN 1861. IjO 



The female of Tarquiniella has acuminate anterior wings. 

 Specimens were exhibited by Mr. Bond at the August 

 Meeting of the Entomological Society of London. 



Gracilaria Kollariella, Zeller. 



Of this very distinct-looking insect a specimen has been 

 found in the collection of British insects in the British 

 Museum. It was purchased of Mr. Bouchard. 



This insect is figured and described in the " Transactions 

 of the Entomological Society of London," vol. i., N.S., 

 p. 193, plate xv. fig. 7. 



The specimen in the British Museum was discovered by 

 Mr. M'Lachlan, concealed amongst' Lyonetia Padifoliella. 



Coleophora Wilkixsoni, Scott. 



Under the above name, Scott has described, in the 

 " Transactions of the Entomological Society of London" 

 (vol. v., New Series, p. 411), aunicolorous grey Coleophoraj 

 the larva of which feeds on birch. 



" The larva mines the birch leaves in August and Sep- 

 tember. The case appears to be made of a portion of the 

 leaf of the food-plant, and is of a dark brown colour, growing 

 deeper, through various atmospheric causes, after the larva 

 has retired to complete its transformation. The case some- 

 what resembles those of Viminetella and PoUtella, but it is 

 longer than the latter and not so long as the former, neither 

 is it bi-coloured, as in those two species. A great character 

 in the formation of the case of Wilkinsoni is a rounded pro- 

 iection towards the middle, on its under side, of a greater or 

 lesser size, the lower edge of which is parallel with the 

 mouth of the case, and rests upon the leaf, both while the 

 larva is feeding and in a state of repose."
