NEUROPTERA. 7k 
S. lutarius; Hemerobius lutarius, L.; Rees., Insect., I, Class 
Il, Insect. Aquat., xiii. Dead-black; light-brown wings thickly 
intersected with black nervures. 
The female produces a prodigious number of eggs, which 
terminate abruptly in a little point, on the leaves of plants or on 
other bodies situated near water. The ova are implanted close 
together, perpendicularly and symmetrically, and form large 
brown plates. The larva inhabits the water, in which it runs 
and swims with great swiftness. The sides of its abdomen, 
like those of the Ephemerz, are provided with pseudo-branchiz, 
and its last ring is elongated into a kind of tail, but it is meta- 
morphosed into an immovable nymph. 
4, A fourth division, that of the Termitin«, will com- 
prise Neuroptera subject to a semi-metamorphosis. They are 
all terrestrial, active, carnivorous, or gnawers, in all their 
states. With the exception of the Mantispi, very distinct 
from all the Insects of this order, by the form of their anterior 
legs, which resemble those of a Mantis, the tarsi consist of 
four joints at most, which removes them from the preceding 
genera of the same family. ‘The mandibles are always cor- 
neous and strong. The inferior wings are nearly as large as 
the superior ones, and without folds, or smaller. 
Some have from five to three joints in the tarsi, and very distinct 
_and salient labial palpi. Their antennz are generally composed of 
-more than ten joints, the prothorax is large, and the wings are equal 
and multireticulated. 
Mantispa, Illig.—Rhaphidia, Scop. Lin.—Mantis, Fab. 
Pall. Oliv. 
Where there are five joints to all the tarsi, and the two first legs 
are formed like those of a Mantis or adapted for prehension. The 
antennz of these Insects are very short and granose, and their eyes 
large. The prothorax is very long, and thickened anteriorly, and 
. the wings are tectiform(1). *
