caraboides, also with its nest and eggs: this beetle does not carry 
a pouch about with it lke the Spercheus, but makes its nidus by 
rolling up a leaf or anything else that comes in its way. One of 
the leaves of some pond-weed is generally selected, and it lines 
this with a thick cottony web-like substance, and in this the eggs 
are deposited to the number of about thirty or forty. 
In ‘Science Gossip’ for June last there is a paper on 
Hydrous piceus, the great water-beetle, with illustrations, which 
give some slight idea of the nest, but that which is supposed to 
illustrate the deposition of eggs in the nest is very incorrect. 
The eggs are not deposited higgledy-piggledy as represented, but 
with great uniformity, each being placed side by side with the 
greatest exactness, standing on end upright, in shape lke elon- 
gated cylinders. 
As regards the nest: the leaf, a floating one, is drawn over 
from the end towards the petiole, leaving the petiole always upper- 
most, and the sides are drawn down and firmly fastened to the 
roll with a kind of gummy secretion, so that the nest is quite 
water-tight; inside is a thick layer of cottony substance of a 
pure white colour, and in the middle of this the eggs are 
deposited, as I said just now, in a horizontal position, side 
by side. They are about a dozen or so in number, of a beautiful 
crocus-yellow colour. These nests were plentiful in the beginning 
of June, but since then none have been met with; the eggs 
of some of these hatched out very soon after they were brought 
home, and the larve were little thread-like things with enormous 
jaws, and evidently very rapacious. This insect’s nest was 
generally attached to a leaf of Sparganium ramosum, but my 
friend tells me he has frequently taken it in a pond where nothing 
grew but Lemna minor, and then any floating substance, even 
pieces of old newspaper, were made use of.
