The Lepidopterological paper in the 
present volume is one of no common 
interest ; it is on the genus Elachista, by 
Professor Frey. 
This paper contains descriptions of no 
less than eighty-five species, and extends 
to upwards of 130 pages. With respect 
to the search for larvae of this genus, 
Professor Frey makes the following 
practical remarks : — 
“ To find Elachisla larvse is in some 
respects difficult, but in others easy. It 
is difficult on extensive grassy plains and 
meadows, but is much more easy where 
the grasses grow less densely together. 
Many species of Carex and Aim ccespi- 
tosa recommeud themselves to the inci- 
pient by their mode of growth. But still 
a careful search is always necessary, in a 
kneeling or recumbent position, and a 
certain amount of training is necessary 
for the eye, but this, after some amount 
of ill luck, we are compelled to acquire. 
“ Most Elachista larvae occur in rather 
shady places, few occur deep in the wood, 
and few in quite open, unsheltered places. 
Edges of woods, whether moist or dry, 
furnish the greatest number of species, 
and I have found young fir woods very 
productive. In dry meadows near woods 
I have found several species, but in the 
marshy meadows near Zurich, hitherto, 
to my surprise, I have found none. 
Those species which are only single- 
brooded appear to occur for a long time 
in the larva state, so that one often 
breeds the perfect insect whilst stragglers 
of the larvae are still to be met with 
(this occurs in Tetragonella, Trape- 
ziella , Quadrella, Adscitella, Cygnipcn- 
nella, &c.) 
“In rearing the species we meet with 
no great difficulty, except in a few which 
are very much infested with parasites. 
We gather the mined piece of grass as 
deep below the larva as we can, carry it 
home in a tin [*and place each kind 
in a glass tube, and keep it in a cool 
place], and the species may be reared 
with ease. 
“ In this respect the Elachistce are far 
more praiseworthy objects than the Nep- 
ticulce. The greater part of the latter 
fail, but the former mostly sueceed.” 
Professor Frey has given, at pp. 184, 
185, some remarks on the geographical 
distribution of the group, but the study 
is yet too much in its infancy for any- 
thing of a satisfactory nature to be said 
on this score. Trained Elachista-hwntevs 
must spend whole seasons in Italy, 
Greece, Sweden and Finland before we 
can be warranted in concluding that the 
genus is as poorly represented in those 
countries as it seems to us at present. 
The 1 Linnasa ’ is a work which is 
already studied by every British ento- 
mologist who is capable of reading Ger- 
man, and to those who have not yet 
attained that pitch of proficiency we 
can only say, if they once begin to learn 
German they will never regret it, but 
they will continually, in after life, regret 
not having learned it. 
BOMBUS TERRESTRIS’ ACCOUNT OF 
HIMSELF. 
To the Editor of the ‘Intelligencer.' 
Sir, — I shall not attempt to describe 
what I saw a few days ago, when I made 
my first excursion, on leaving my Hi- 
hernacula ; no person can do it, — no 
* We have altered Professor Frey’s 
words here a little, to make it accord 
better with our own experience.
