THE ENTOMOLOGIST’S WEEKLY INTELLIGENCER. 
night since I took a specimen of Cubicu - 
laris (on ivy), which was very much in- 
fested ; many of the red gentlemen are 
on it now. I observed in the summer 
that Puphia, Aglaia and Galathea had 
many of them, and should certainly like 
to know a little more about them. —

Captures at Newnham. — This district 
is improving ; I have taken Ennomos 
Fuscanlaria , and, better still, a specimen 
of Prodelia lileralis, on a gas-lamp at 
the side of the Severn. The ivy is nearly 
over, and has only produced one Xanthia 
Aurago, one pair of Nonagria Crassi- 
comis, and some few common things. 
Himera pennaria is just making its ap- 
pearance, in company with Hibernia 
defoliaria. — Ibid. 
Ennomos Fuscantaria. — I captured a 
specimen of this insect on the 27th of 
August last, on a gas-lamp near Ken- 
sington. — J. H. Tilly, 3, Bernard Street,

Success at Sugar. — During the last 
three weeks I have taken the following 
insects at sugar: — O Lola and Maci- 
lenla, A. Rufina , abundant; H. Croceago, 
X. Flavago, Gilvago and Ferruginea, 
E. Fulvago, P. Flavocincla, A. Aprilina , 
common; C. Vetusla and Exolela , X. 
Rhizolitha, and several other common 
species. I was surprised to see so many 
complaints, a short time ago, with regard 
to non-success at sugar, and think it 
must be attributed to the kind of sugar 
used, as each time I have sugared this 
season has been attended with success, 
except upon one occasion, which was a 
very cold night in September. One 
gentleman writes that he only met with 
one wasted Xanthographa the whole 
evening: this indeed must have been 
poor sport. On the evening of the 22nd 
of August I sugared in Bishop’s Wood, 
Hampstead, and Noctiuc were exceed- 
ingly plentiful : some idea may be formed 
of their abundance, when upon one tree 
I counted eighty-three Xanthographa. 
My method of making sugar is the follow- 
ing: — Warm half-a-pint of ale, in which 
dissolve half-a-pound of Foots sugar and 
about the same quantity of treacle; when 
cold, add half a wine-glassful of rum 
and five drops of essential oil of bitter 
almonds. I have given this recipe to 
several of my entomological friends, all 
of whom are much pleased with it. — 
E. G. Baldwin, Albany House, Barns- 
bury Park ; October 26. 
Peripatetic Larvae. — When we observe 
caterpillars journeying on the highway, 
knowing that they have for hundreds of 
days lived and fed in the heart of some 
tree, the mind naturally inquires what 
motive causes this singular proceeding : 
is it a casual or capricious act, or is it in 
obedience and under the agency of some 
determined law ? In the case of the Cossus, 
I would hesitate in ascribing it to acci- 
dent, because they do not fall from the 
tree, but must deliberately eat their way 
out from the pith ; if attributed to ca- 
price, then there are many possessed with 
this unaccountable whim, for I myself 
have captured several sojourning in the 
highways, and they all readily changed 
in sawdust, which clearly showed that 
they were designedly leaving the tree to 
change in another quarter. We have 
heard of the cocoons of the Cossus being 
found in trees ; if that be their natural 
place of transformation, why do so many 
leave on the eve of their change of form? 
Can it be that they are under the do- 
minion of some natural law ? for in- 
stance, that the muscles of locomotion in 
those that are highly developed become 
irritably excited prior to transformation ? 
thus inducing an erratic propensity as a 
means of assuaging the excitement, and 
probably to facilitate their change. The 
larva of Phragmatobia Fuliginosa is like- 
wise a wanderer : many a time have I 
observed them eagerly pursuing their way, 
evidently on the search for an liyberna- 
culum to pass the winter in. When 
placed in confinement at this time, they
