112 Mr. Kirgy on a new Species of Europuus Geoffroy. 
a pair of rose-coloured rather hairy horns or papilla. On each 
segment of the body was a transverse series of longish black 
hairs. 
On the 19th of the same month, seventeen parasitic larvæ 
broke forth from my caterpillar. They were of a conical shape, 
and resembled those which De Geer found upon the horse- 
chesnut*, the head being truncated and the other end acute. 
They were of a pale-green colour, and, like those of De Geer, 
besmeared with a kind of varnish or gluten, by which they were 
enabled to adhere to the lid of the box the caterpillar was in, 
around the exuviæ of which they arranged themselves. Pre- 
viously to their becoming pup:e they voided all their excrement 
in the form of little oval pea-green grains, seven or eight in num- 
ber, which remained fixed at a little distance from them. About 
the 23rd they had assumed the pupa, which was of the angular 
kind, and from green had changed to a ferruginous or reddish- 
brown colour. On the first of August the fly appeared, when, 
being suddenly called from home, I had not time to attend to it 
further than to wrap up the box carefully in paper to prevent 
their escape. On my return ten days afterwards I found, how- 
ever, that four had contrived to get out ; for all the pupæ, their 
cases remaining fixed to the lid of the box, had produced flies, 
and I could deta only thirteen, all of which were dead, 
namely, twelve females and one e male. I shall now describe my 
little fly. |
