being a female. The next specimen I took was on the 24th 
of May; this was also a female, and laid about a dozen eggs. 
These eggs hatched on the 2nd of June, and the young larve 
fed for a month, and then spun up (July 6th and 7th). The 
imagos from these emerged on July 20th and 2lst; and 
I obtained a further supply of eggs. The young larve 
hatched from these, fed well till the beginning of August, 
when they all died off, on account of being left in a window 
in a scorching sun. Had these larve lived and turned 
into pupe, I believe that the imagos would have emerged 
this year; and this supposition is founded on the fact of my 
having taken a specimen of Hamula (at light) on the 21st of 
September last year. Thus, it appears to me that there must 
be three broods of Hamulaa year. I believe that Lacertula 
is also triple-brooded, but have not positive proof. As in the 
case of Hamula, [ took the first specimen of Lacertula on the 
24th of May this year, and the larve produced from eggs 
laid by this female turned to pup on July 2nd, feeding up 
much more slowly than those of Hamula. The pupz were 
only three in number, two of which emerged on the 11th of 
August, and one sull remains in the pupa state. The two 
imagos laid a batch of eggs, which unfortunately proved 
unfertile. Had they hatched into larve the imagos would 
probably have appeared in September. I mentioned in the 
‘Entomologist, last year, the capture of a specimen of 
P. Lacertula at the end of April, and I now believe that 
it was a hybernated specimen of the September brood of 
1869, since it was not freshly emerged, nor have I ever met 
with the perfect insect before the 20th of May.—G. 4.

Breeding Cossus Ligniperda and Zeuzera Aisculi.—For 
the information of Messrs. Arthur du Moulin and J. R.S. 
Clifford, I venture to send a few remarks respecting C. Lig- 
niperda and Z. Aésculi, having had much experience with 
both species. I do not think the method you suggest with 
Ligniperda larve would prove effectual, as muslin would not 
restrain them. Both species should be taken when full fed. 
When I first tried Cossus larve they ate through a half-inch 
deal box, and finished up by devouring a lot of cork setting- 
boards. I next tried them by putting some willow-stumps, 
containing the larve, in a small brick house | built in my
