Coleophora Olivaceella. — Mr. M‘Lach- 
lan has called my attention to the fact 
that, owing to the curve of the mouth of 
the case of this species, a feeding larva 
reposes nearly prostrate on the surface of 
the leaf, whereas a feeding larva of Soli- 
tariella is almost erect, making at least 
an angle of 60° with the leaf. -H. T. 
Stainton; May 18. 
Coleophora saturatella. — From the cases 
of this species, collected during the past 
three months, and which have remained 
perfectly still during that time, I am now 
breeding many ichneumons, and a few 
days since, on looking in the cage, was 
surprised to see what were evidently the 
young larvae of this species, in very 
grotesquely minute cases, marching up 
the sides. Now this appears to me to 
prove in this species two new facts, e.xcep- 
tional in the history of this genus ; first, 
that from the time of the egg being laid 
to the appearance of the imago nearly 
two years must elapse, for as the perfect 
insect does not appear till July, and sup- 
posing the egg to be laid at the end of 
that month, it (as is proved by my young 
larvce) is not hatched till the following 
^lay, and is full fed the same autumn, 
the imago appearing the following July — 
a period of twenty-two months and a half ; 
secondly, the larvre of this species are not 
miners when very young, as in, I think, 
most others of the genus, but commence 
manufacturing a case immediately on 
their exclusion from the egg, apparently 
in mine from pieces chipped off the old 
cases. They are now actively feeding, 
causing brownish blotches on the brown 
leaves. — E. M‘Lachlan, Forest Hill;

Coleophora saturatella. — In June of 
last year I found, at Wanstead, two cases 
of the above species, from one of which, 
in due time, I bred a beautiful specimen^ 
In March of the present year, acting upon 
the information given by Mr. M'Lachlan^ 
in the ‘ Intelligencer’ (No. ] 79), I went 
to Hampstead Meath, and there found a 
great many cases of the species in ques- 
tion. All of these were attached to the 
topmost twigs of the bnrom, and at the 
time I was disposed to think they con- 
tained larvae which had nearly or quite 
finished their feeding in the autumn, and 
selected this position to undergo their 
final change. I was not a little sur- 
prised, however, about a fortnight back, 
to find that these cases had many of them 
a small hole in the side, and that several 
ichneumons were wandering about the 
jar; these continued to appear until it 
was quite a “case” with my breeding 
anything else. On Saturday last I again 
visited Hampstead, and on diligently 
searching the broom was rewarded with 
a small fresh case of the species. It is, 
therefore, certain that the larvse of this 
species do not really commence work be- 
fore the spring, aud that all the large 
full-sized cases we may find in the early 
spring months are infested with the para- 
site of the species, and are therefore 
useless. — C. Miller, 17, Silurian Ter- 
race, Broke Road, Dulston; May 17. 
Coleophora saturatella. — The two pre- 
ceding notices will have been read with 
considerable interest. The fact of most 
of the winter-collected cases containing 
ichneumons is undoubtedly curious, and 
at variance with our previous observations 
of these parasites. But, with reference 
to the larvae of the Coleophora, I see 
nothing to prevent the infant larvm now 
feeding from being full fed by the end of 
J une, 1 860, aud producing perfect insects 
in July and August of the same year. 
These might lay eggs, from which young 
larvae would be excluded next spring. 
As the observations of the current sum- 
mer will probably decide these points, it 
will be interesting to watch the career of 
the so-long-waiited and now-so-abund- 
antly-found larva) of Coleophora satura- 
tella. — H. T. Stainton; May 19.
