j name of Mespilicola ; the name Ari<e 
( must therefore sink. The other species 
described by Herrich-Schaffer (Int. viii. 
176), of which I now possess original 
' specimens, are all good distinct species. —

! Elachlsta Nobilella bred. — In the 
! ‘ Linnaea Entomologica ’ (vol. xii. p. 200) 
' I mentioned that I had bred a specimen 
! of this insect. I now know its mode of 
i life. The larva,__which is slender, yel- 
lowish, with a brown head, is nearly full 
' fed before winter, and is found in March 
^ in a species of Festuca, wirich grows on 
the dry slopes of our mountain woods, 
f The mine is long and white, and the 
: larva often appears to go from one leaf 
j to another. The pu[ia reminds one of 
that of JElachista Gieichenella, — Ibid. 
' Gracilaria Populetorum. — I have un- 
! fortunately no description of the larva 
i and habit of this insect, and last year I 
j sought for it in vain. Only this much I 
j do remember with certainty, that the 
larva lived in rolled-up leaves and ?ioi in 
j cones. I found it years ago on young 
[ birch trees in an open part of the wood. — 
! Ibid. 
' Gracilaria Rufipennella and Hemi- 
' dacUjlella. — The larvae of both species 
I occur here in cones on Acer pseudo- 
I platanus, but I have not been able to 
1 distinguish them. The specimens which 
i you and I bred last autumn, from the 
! mines which were found here at Zurich, 
j are to this day somewhat doubtful with 
! me. They possess the same peculiarity 
I in the legs as in G. Rufipennella, and 
j may possibly yet»be only one of the 
i numerous varieties of that species. Be- 
! sides of G. Hemidachjklla I only possess 
an old specimen from Vienna. I will 
j during the present summer more atten- 
tively study the cones on Acer. On Acer 
campestris we find only G. semifascia 
here, and no other species. — Ibid. 
[From the last sentence, we presume 
we were in error in stating (p. 24) that 
Professor Frey had sent cones on maple 
i 
leaves which produced G. Hemidactylella ; 
they must have been cones on sycamore^ 
Glyphipteryx Fischeriella bred. — I 
have this morning bred G. Fischeriella 
from the larva which I mentioned the 
other day as suspected to be this species ; 
the larva lives in the seeds of Daciylis 
glomerala and various other grasses. I 
first found the larva on the 19th of 
August, I860, nearly full fed; you can 
see little or no trace of the larva unless 
you collect some of the seed-heads and 
put them into a glass, and look at them 
in a day or two; you will then see where 
they are at work. — T. Wilkinson, Cliff 
Bridge Terrace, Scarborough ; May 17, 
1861. 
Chrysoclisla Flavicaput bred. — The 
larva of this species feeds in the interior 
of hawthorn twigs, and changes to the 
pupa state in situ, so that the pupae may 
be readily collected. Mr. Simmons sent 
me some pupae at the beginning of April, 
and pointed out that an oval opening in 
the side of the twig indicates the locus of 
the inhabitant. Fibm the consideration 
of these pupte and their habitat I sus- 
pected that they would produce Chryso- 
clisla Flavicaput, and this conjecture has 
been satisfactorily confirmed, Mr. Archer, 
of Trinity College, Cambridge, having 
bred the perfect insect, which is now ap- 
pearing here from hawthorn twigs for- 
warded by Mr. Archer.— H.T. Stainton ;

Cecidomyia Salicis, Schrank. — In May 
last I gave some account of the gall-gnat 
(C.rosaria) that is instrumental in form- 
ing the rose-like galls on the willows. I 
have lately hatched another of the willow 
gall-gnats, whose economy is difi'erent : 
this is the C. Salicis. By the operation 
of this gnat the twig is made to assume 
a rounded woody knot. The twig con- 
tinues indeed to grow beyond the knot, 
but from the juices being appropriated 
it is sickly and struggles for existence. 
Meantime the knot becomes the home of 
the larva; through the autumn and
