102 THE ENTOMOLOGIST. 
on the leaves of the apricot, but the imago of which I have never 
taken. The larva of Lyda clypeata was first described by Frisch, 
who did not succeed in rearing the insect; next by Réaumur, who 
was equally unsuccessful, and subsequently by De Geer, who was 
more fortunate. 
I found the larva near Heemstede, on pear trees, but I have 
no notes of the particulars. In the autumn of 1861, on the 2nd 
of October, my colleague Herklots brought me a number of 
larvee which he had met with, also on a pear tree, at Warmond, 
where he was then living; fig. 1 is drawn from one of these. 
The larve of the genus Lyda are known to have no middle legs, 
and to live in a web in somewhat considerable numbers. The 
description of my larve, taken down at the time, is as follows :— 
The body is robust rather than slender, of an orange colour, in 
which at some times the red and at others the yellow tint 
predominates. The head (fig. 2) is shining black, and globular ; 
the situation of the eyes is not so readily distinguishable as it is, 
for example, in the larva of Cimbex. The two long antenne 
(fig. 3) to be seen at the sides of the forehead are composed of a 
number of joints, and are annulated with pale and dark brown ; 
they are placed on an oval excrescence of a pale brown colour, 
which might be regarded as the first joint. The jaws are black; 
palpi and labium yellow, annulated with black. 
The body is strongly wrinkled, being, however, nearly flat 
underneath ; on the back the middle segments are divided into 
four larger folds. On the first segment, on either side of what 
might be described as the neck, is a triangular shining black spot, 
and just before the base of the anterior pair of legs is another 
similar spot, but much smaller. The openings of the stigmata 
were so narrow that I could not clearly make them out. ‘The 
last segment of the body (fig. 5) is rounded at the end, and at the 
same time somewhat flat; it has on either side a little leg of a 
singular form, consisting apparently of two joints, of which the 
first is thin, cylindrical, and rather long, and the second pointed, 
with the basal half of an orange colour and the remainder shining 
black (fig. 6). 
In addition to the absence of middle legs and the singular 
arrangement of the antenne-like posterior legs, there is another 
circumstance by which these larve are distinguished from those 
of other Tenthredinide, namely, that the antenne are placed
