THE WEEKLY ENTOMOLOGIST. 
until I had fifteen of various shades 
of color. Among the very latest 
that came out, one pair got in cop. 
The female was of a pretty lilac tint, 
the male deep grey, strongly 
marked. 
The ova speedily hatched, the 
larvce fed up quickly and went down. 
About ten days since, imagos made 
their appearance, and within four 
days, I had out thirteen, from the 
twenty-four pupae that went down. 
Although these were all bred from 
the same hatch of eggs, and all fed 
on twigs gathered from one poplar 
tree (Lombardy), yet they differ 
very widely in color. Some are of 
the lightest possible grey, others are 
of a strong red tint, the bodies of 
some being quite pink. I now have 
fertilized eggs from the second 
brood, the imagos of which, as a 
rule, are smaller than those of the 
first brood. 
As the leaves of the food plant, 
collected near London, are much de- 
filed by soot and dirt, I generally 
well wash them in pure water, and 
placing the stalk in water, let them 
remain in a current of air, until the 
moisture has dried off the surface of 
the leaves, before I place the larvce 
upon them. I beg to recommend 
this plan to those who have to 
collect their feeding plants near 
large towns. — William Horn, 21,

Are the Smennthi double brooded ? 
— I perceive the above question has 
been asked in No. 25 of the “ Ento- 
mologist,” of August 1st. I took a 
male specimen of 8. Poimli in good 
condition, apparently not long 
emerged from the pupa. Perhaps 
this may help to confirm the opinion 
of some entomologists that the 
Smerinthi are double brooded, during 
such a warm season as the one we 
have just experienced. I took two 
of S. Populi at the latter end' of 
May ; so, if the insect is not double 
brooded, it is certain specimens are 
to be taken during several months 
of the year. — George B. Corbin,

CAPTURES. 
Lepidoptera. 
Theda Belulce in Westmoreland . — 
Yesterday, I saw a female Betulce 
on the road side near Wliitbarrow. 
I stood looking at it, folding and 
spreading its wings, and walking 
about on a bramble leaf, to get a 
good stroke with the net, but all in 
vain. It did not seem disposed 
to go away, and I was obliged to 
strike it as I best could, and knocked 
it down among the brambles. She 
was not long then in mounting to 
the top of some trees, where, in the 
Hairstreak fashion, she soon found 
two mates, either to pluy or fight
