Geoffroy, but which are removed from them by the number of joints 
in their tarsi, under the generic name of 
SemsBuis, F'ab., 
Which is composed of the following subgenera : 
Corypauis, Lat., 
Distinguished by the mandibles of the male, which are very large 
and resemble horns *. 
Cuavriopes, Lat., 
Where the antenne are pectinated f. 
Srauis, Lat., 
Where the mandibles are moderate, as in ‘the latter, and the an- 
tennz simple as in Corydalis, and distinguished from the two pre- 
ceding ones by the tectiform disposition of the wings. To this sub- 
genus belongs the 
S. lutarius; Hemerobius lutarius, L.; Rees., Insect., II, Class 
II, 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 
tegether, 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-branchie, 
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 Termitine, will comprise Neu- 
roptera, subject to a semimetamorphosis. They are all terrestrial, 
active, carnivorous, or gnawers, in all their states. With the excep- 
tion of the Mantispze, 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 
corneous 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.
