varies much in intensity. A batch of larve that I had last 
year, belonging to Subsericeata, scarcely possessed that 
marking, whilst those (or some of them) I had lately were 
very conspicuously blotched.” Subsequently, when in Hud- 
dersfield, Mr. Barrett saw my Subsericeata larva, and found 
they varied very much from those he had reared; indeed, my 
Mancuniata were more like his Subsericeata than were my 
larvee of that species. I offer no opinion as to the distinct- 
ness of the species.— Geo. T. Porrilt; Huddersfield,

Entomological Notes, Captures, Sc. 
Early appearance of N. Lucina.—On the 7th of June I 
obtained seventeen eggs of N. Lucina, which commenced 
hatching about the 13th, the larve feeding till the 17th July, 
when only three survived: these went to pupa about this date, 
and were left in a cold room. On the 6th of October I was 
surprised to find one had emerged, a beautiful specimen ; 
and on the 20th of the same month another made its appear- 
ance, though not quite such a perfect specimen as its 
predecessor. The third is still in pupa, in which state I 
conclude it will remain like a rational insect until June 
next, which, | believe, is the proper time for its emergence. 
Is not this unusual, where the pupz were kept in a cold 
temperature ?—JZ. N. Inman. 
The Genus Platypterya.—From facts I have observed in 
connection with this genus, I have arrived at the conclusion 
that they are very capricious in their appearance, and may 
be met with from early spring to the close of the autumn. 
Hamula seems to be triple-brooded; and very probably 
Lacertula also. Both of these I have reared from the egg, 
but have never succeeded in obtaining eggs from Unguicula 
or Falcula, so that I know little of their economy, but have 
taken them by beating in May and June, although | have 
never been able to discover any second brood in September. 
I shall be glad to hear of the experience of any brother 
entomologist with respect to these two species (Falcula and 
Unguicula). The first specimens of Hamula which I took 
this year were on the 20th of May, three in number, one
