OBSERVATIONS ON 
Elackista 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 
timesfound 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 Holm 
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 . cygnipemella } 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 * 
pennella , but I am now desirous to suspend my opinion till 
further observations have been made. When at Dawlish 
last May I collected an Elackista 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 
ray specimens can be distinguished from E. cygnipennella- 
Tischeria complanella , I. B., p. 264. Mr. Wing bred
