268 THE ENTOMOLOGIST. 
Selandria parva, nigra, nitida, tibiarum tarsorumque basi 
alba, alis fusco-nigris, apice hyalinis. 
A glance at our engraving will show that we have here to 
do with an insect related to Selandria ethiops, Z., the well- 
known caterpillar of the pear-tree; indeed, Ratzeburg’s 
description of the one follows immediately upon that of the 
other. In a systematic arrangement, however, they would 
not be placed so near together; they are in the same genus 
of Hartig, but, on account of the difference in the neuration 
of the wings, not in the same division: this may suggest the 
question whether the divisions of this author, according to 
the neuration, are always equally natural,—a question which 
I hope to answer, if I succeed in rearing a third species of 
caterpillar (nut-brown, living on the oak). 
At the end of May, 1866, l took a female of Selandria 
annulipes, on a lime-tree in my garden, after the insect had 
been flying about for some time in the sunshine among the 
large leaves of that tree. On the 8th of June following I 
perceived some very small caterpillars on the under side of 
a leaf of the same tree (see fig. 1,a, a, a): not far from each 
of these larve was a little pocket, formed of the skin of the 
leaf (fig. 1, b, 6, 6), of a very pale green, and having a little 
hole bitten out of the middle; in these pockets the eggs had 
been placed, from which the larve had emerged. Ratzeburg 
has made precisely the same observation, as appears in his 
work, referred to at the head of this paper. The larve 
gnawed little pieces out of the under epidermis and 
parenchyma of the leaf, as represented at fig. 2, magnified, 
so that the leaf on which they lived was speedily covered 
above and below with little brown spots, where the cuticle 
only was left. Afterwards, when many larve have damaged 
the leaf in this way, it dies and curls up, which has induced 
Ratzeburg to class Selandria annulipes as specially injurious 
in gardens. 
My young larve were very shining, as if they had been 
covered with varnish: they were of a very pale gray, with 
nut-brown heads; the anterior segments of the body were 
broad, narrowing posteriorly; the broad intestinal canal, 
which was of a green colour, showed through the body, and 
had a black longitudinal line at the end, which was simply 
the excrement seen through the skin. I counted twenty-two
