PERICALLIA SYRINGARIA.— Having noticed an article on this 
species as double-brooded, in the December number of the 
‘Entomologist,’ I thought that my own experience with it this 
season might interest some. Having obtained a batch of eggs 
this spring, I sleeved them out on a privet hedge, and expected 
them to hybernate as larvee; consequently I was a good deal 
surprised when, on examining the sleeve in July, I found it 
contained a good number of pup. I opened the bag and found 
that about one quarter of the larve were still small, while the 
greater part of the batch had pupated. ‘The latter emerged in 
August, and their progeny are now hybernating together with the 
remains of the former brood, from which they scarcely differ in 
point of size. I never bred this species before, and had no idea 
that it was double-brooded, but on discovering this to be the case 
I examined the authors I had to refer to, and find that, of English 
works, ‘ Merrin’s Calendar’ gives as its time of emergence v1., Vii., 
and s. vii., while Guenée says simply May and August, and 
Treitschke calls it distinctly double-brooded, the second brood 
being “less numerous, but more productive than the first,” by 
which, I suppose, he was not aware that this brood is only a 
partial one.—F’. D. WHEELER; Chester Place, Norwich. 
CATOPTRIA &MULANA.—There are two forms of this insect 
under the above name, which I believe will prove to be distinct 
species. One form I have bred in some numbers from larve 
found feeding in the seed-heads of golden-rod, collected at the 
end of September ; and in October, in woods in Kent and Surrey. 
The other form occurs on the salt-marshes at the mouth of the 
Thames, and has not yet, I believe, been reared from the larve ; 
this I have never taken, having no opportunities of working its 
localities. The salt-marsh form is considerably larger than that 
reared from the golden-rod,—its markings are more distinct and 
silvery, and its colours brighter. Professor Zeller considers 
them identical; but my friend, Mr. C. G. Barrett, thinks these 
two forms may prove distinct species, but waits for proof. Its 
larve is likely to be found on some of the composite flowers 
(possibly Aster tripoliwm) growing at the mouths of rivers near 
the sea. Cannot some of the numerous readers of the ‘ Ento- 
mologist,’ who are in the habit of visiting our favourite watering- 
places in the autumn, succeed in finding the larve and send a 
few to my friend for examination, and settle the question of their
