of this species at large in the Essex marshes. The only 
other recent captures have taken place in the North of 
England and in Scotland, as recorded in the ‘ Entomologist ;’ 
and in each case only one was seen. If Mr. Button can 
communicate any further particulars as to the habits of the 
species, I trust he will do so. I presume that the individuals 
occurring there are of the typical form, and not the dwarf and 
dark variety common amongst breeders. Unquestionably the 
species was once pretty common in many places in Britain ; 
and it is not, seemingly, a delicate species nor a dainty 
feeder. It is not at all evident why it has almost become 
extinct.—J. R. S. Clifford. 
Young Larve of Zeuzera Aisculi.—lI have never been able 
to rear these in confinement, nor do I suppose others have 
been more successful. On one occasion I had an opportunity 
of observing the hatching of a patch of eggs deposited 
on a pear-tree. These I noticed particularly did not at once 
penetrate the wood, but fed for several weeks between the 
bark and the wood. Unfortunately the loose piece of bark, 
under which they were living, was accidentally wrenched off, 
and heavy rain coming soon after, the young Jarve were 
washed away. ‘This is only a solitary instance, and it might 
be assumed that something peculiar about the wood of this 
tree prevented them from at once penetrating it; so I would 
hardly venture to assert that it is the habit of the larve 
to feed at first in that. manner, until it gains strength and 
size ; yet, for all that, it is not improbable.—J. R. S. Clifford. 
Halias wavaria.— Your correspondent, Mr. G. Sim 
(Entom. No. 96, p. 416), appears to consider it an unusual 
occurrence for the larve of H. wavaria to undergo pupation 
under ground. I have had, at various times, great numbers 
of the larvee of this moth, and have invariably found that they 
turn to pup under ground, but without forming a cocoon; 
and, although I have searched for the pupa above ground out 
of doors in our garden (where, this spring, I captured twelve 
dozen larve in one afternoon), | have never yet succeeded in 
finding it, and so conclude that it has the same habits 
at liberty as those it has in captivity. This species appears 
to be very prolific. As mentioned above, I took, this year, 
great numbers of larve off gooseberry and currant. After that 
our gardener destroyed many dozens more; and I suppose
