THE ENTOMOLOGIST’S WEEKLY INTELLIGENCER. 
rotten wood and fungus I have taken the 
following : — 
Scaphidium quadrimaculatum, 
Ips quadriguttatus, 
Rhj'zophagus femigineus, 
bipustulatus, 
Thymaliis liinhatus, 
Bitoma cienata, 
Cerylon hisleroides, 
Mycetophagus atomavia.

OBSEEVATIONS. 
Lasioeampa Quercus or Callunce . — In 
reply to Mr. M‘Lachlan’s question as to 
the identity of the species bred from 
pupse collected in the spring, I must 
confess niy inability (as some years have 
intervened since I collected any pupae of 
X. Quercus) to make any definite reply. 
From various reasons, however, I must 
say that were they Callunce, and, as I 
had not then heard of that variety of 
Quercus, they might have been, I can 
assure him that several of my males 
paired vvith females which had remained 
in pupae the usual time. Also, as by 
stinting the larvae in food retards thus 
considerably their development (which 
I have more than once myself done), I 
cannot think that those which remain 
till spring can be a different species ; for 
I believe it is considered to be contrary 
to the law of Nature to change one spe- 
cies into another, even when assisted by 
the most perfect artificial means. Be- 
lievers in Darwin may think otherwise, 
but they are in a respectable minorit}. 
I think if Mr M‘Lachlan had carefully 
read ray notice, he would have seen the 
manifest improbability, on account of the 
latter circumstance, of such an occur- 
rence. I have, however, written to a 
friend in the North, asking him to send 
me any spring pupae he may have; 
and, by that means, I hope to throw 
some additional light upon the sub* 
ject. — E. Tyrer, Crouch End, Hornsey ;

Acidalia inornata . — I am happy to 
say that I have succeeded in breeding 
this insect from eggs laid by a female 
last August. The young larvte made 
their appearance in about fifteen days, 
and fed on sallow until the beginning of 
November, then they began to be stupid, 
and ceased to feed, though during the 
winter months I tried them with any- 
thing that was green, but all to no use. 
I never saw that they touched anything 
until the beginning of April, when they 
moulted their last skin, and I supplied 
them with Vaccinium myrtillus, which 
they fed on ; no doubt that plant will 
prove to be their natural food, though I 
have searched for the larvae at the locality 
this spring, but failed to find any. I 
should be very happy to hear from any 
entomologist that is in the habit of cap- 
turing this insect, if it occurs in a locality 
where Vaccinium myrtillus does not 
abound; that will put the question at 
rest at once. — James Batty, 133, South 
Street, Park, Sheffield ; June 5. 
EXCHANGE. 
Arclia Caja . — I have larvae of this in- 
sect, which I should be glad to exchange 
for any local variety of butterfly. I have 
also larvae of Ligdia adustata to exchange 
for Gonepteryx Rhamni, and a quantity 
of Abraxas Grossulariata for any other 
variety. If any one is in want of 
either of these two last-named species, I 
will send a few' on receipt of boxes ad- 
dressed and stamped. Those who have 
anything to exchange to write before 
sendinghoxes. — John Russell, Halling-
