80 OBSERVATIONS ON 



Elachista biatomella, I. B., p. 260. Mr. Wing and I 

 found the larvae making whitish blotches in the leaves of a 

 Carex on the steep side of Box Hill last April. We several 

 times found the pupa placed in the angle of a lower leaf than 

 that which had been mined. 



E. triseriatella, I. B., p. 261. No longer unique, a spe- 

 cimen having been taken by Mr. Hogan, at Howth, Ireland, 

 last summer. 



E. rufocinerca, I. B., p. 262. In February and March 

 this larva is abundant in the leaves of those plants of Holcus 

 mollis which grow under hedges, and on the sides of ditches ; 

 it makes broad whitish mines, in which there is very little 

 excrement ; it is excessively subject to the attacks of ich- 

 neumons. 



E. cygnipennella, I. B., p. 262. In the Entomologische 

 Zeitung for 1853, page 415, Zeller describes a species closely 

 allied to this, which he names E.festucicolella, having found 

 it in a dry place among Festuca ovina, and he mentions that 

 I had informed him it also occurred in England. I alluded 

 to two small specimens taken by Mr. Douglas at Chelten- 

 ham, in July, 1853, which I thought distinct from cygni- 

 pemiella, but I am now desirous to suspend my opinion till 

 further observations have been made. When at Dawlish 

 last May I collected an Elachista in great numbers, which 

 was evidently attached to the Festuca duriuscula growing 

 on the sandy banks ; the perfect insect was always sitting on 

 the stems of that grass, and I observed leaves of the grass 

 which had been mined by an Elachista larva. I concluded, 

 of course, this would be E. festucicolella, and laid in a 

 supply for all my correspondents, but unfortunately have 

 hitherto been quite unable to detect any character by which 

 my specimens can be distinguished from E. cygnipennella.
