eggs were visible to the naked eye, but one was larger than the 
other. On the 26th the larger egg had enlarged, and a portion 
of it was white. 28th. Still more enlarged. 29th. More enlarged ; 
it now looked like an elongated bladder with a kind of footstalk, 
which was firmly attached to the caterpillar under the bladder- 
‘like looking object; a portion of the dark egg was still to be seen 
between it and the beginning of the footstalk; the bladder-like 
object or grub was in segments, was transparent white, with white 
tree-like opaque markings, and there was something dark forming 
inside it. 30th. Stilllarger. 83lst. Larger; it was by this time 
a quarter of an inch long, and formed an arch over the caterpillar’s 
neck. For several days past the poor caterpillar had tried in vain 
to rub off this unwelcome guest, but all its efforts were in vain. 
September lst. Larger; the caterpillar had by this time become 
very torpid, and had lost its beautiful colouring. 2nd. Larger, 
and nearly opaque white; and by three o’clock, p.m., it had come 
off, and was half an inch long; the grub had no legs, but used 
the posterior part of its body to move itself about with, but it did 
not do much more than tumble about incessantly ; by this time 
the caterpillar was dead. 3rd. The released grub was still 
larger, but not so lively; and on the 6th had changed from 
cream-colour to bright yellow. October 12th it began to darken, 
and on the succeeding day was chocolate-brown, had shrivelled up 
to half its former size, and appeared dead. It had evidently died 
in the act of spinning its cocoon, or in changing into pupation. 
On two occasions I submitted the larva, with its unwelcome 
guest on it, to the inspection of the best practical entomologist 
we have in this town, and he said he had never seen anything of 
the kind before on a caterpillar, although he had had thousands 
of lepidopterous larve under his care. I enclose the smaller 
ega; the piece of skin which came off the Acronycta caterpillar, 
and which had, when on, the appearance of a footstalk; also the 
grub in its changing state, when it died; and shall be obliged for 
any information on the subject.—Ciara Kinesrorp; Barton 
House, Canterbury, January 6, 1883. 
[The objects sent were quite unrecognisable when received by 
me. There can be little doubt, however, but that the external 
parasite alluded to is Paniscus cephalotes, Holmgren,—one of the 
Ophionide (ichneumons), whose interesting economy has been so 
lately referred to in these pages by Mr. E. W. Andrews (Eutom.
