THE ENTOMOLOGIST. (lt § 
living,—all these circumstances seemed to make the subject 
anything but attractive. At last, however, on a peculiarly 
favourable opportunity presenting itself for rearing the larva 
in question, I made up my mind to the task, and, as I 
had found a considerable number in my garden, I took some 
of them indoors for the purpose of examination and observa- 
tion. This was on the 20th of June, 1867. Unfortunately, 
the larve were nearly, if not quite, full grown. I think, 
however, that I remember observing that the younger larve, 
which I had before seen, differed from the more advanced 
examples merely in size. 
The head (fig. 3) was of the usual form, somewhat 
depressed anteriorly ; its colour was grayish green, the eyes 
being placed in rather large, round, black spots; from each 
of these spots proceeded a brown line, narrowing gradually 
and going to the top of the head, where the lines joined. 
There were some small brown spots about the trophi, and the 
teeth of the mandibles were of the same colour. The body 
was rather long and slender (see figs. 1, 2), and had 
altogether twenty legs. Above the line of the tracheex the 
body was strongly wrinkled; 1 counted five folds on each 
segment. The lst segment, the borders of the stigmata, the 
middle and posterior legs, the 11th segment, and the anal 
valve, were of a green-yellow tint; the remainder was green. 
On either side of the neck behind the head on a level with 
the eye was a fine black curved line, like a chevron reversed ; 
a similar mark occurred above each thoracic leg (fig. 4); the 
claws of these were brown. 
The little animals were nearly two centimetres long; their 
usual position was. at full length along the edge of the leaf, 
the posterior segments being slightly curved, as shown at 
fig. 1; less frequently they were observed in the curved 
position of fig. 2, this being otherwise the usual posture of 
many species of Nematus. When they were full grown they 
descended from the leaves to the ground, where they spun up, 
under cover of some of the fallen leaves, in little shining, | 
brown cocoons, some being of a paler tint than the others. 
Their original colour and appearance is shown at fig.5. The 
cocoons in question were single, and between six and seven 
millemetres long. On the 16th of the following July I found 
two females had made their appearance in the jar in which |
