30 INSECTA. 
Repvuvius, Fab. 
Or Reduvii properly so called. The body is an oblong oval, and 
the legs of a moderate length. , 
We may unite with them the Vabis, Lat.(1) and the Petalocheires 
of Palis. de Beauvois; the anterior tibiz of the latter are clypeiform. 
R. personatus; Cimex personatus, L.; Punaise mouche, Geoff., 
I, ix, S$. Length eight lines; blackish-brown and immaculate. 
It inhabits the interior of houses, where it lives on flies and 
other insects, approaching its prey slowly till within a certain 
distance, and then darting upon it. Its stings kill it in an in- 
stant. The larva and nymph resemble ‘a spider covered with 
dust and dirt(2). 
ZELus, Fab. 
Where the body is linear, and the legs very long, extremely slen- 
der, and alike(3). 
Proraria, Scop.—mesa, Fab. 
Analogous to the preceding Insects in the linear form of the body, 
and the length and tenuity of the legs; but the two anterior ones have 
elongated coxz, and are adapted, as in Mantis, for seizing their 
prey(4). 
We now come to Geocorisx, remarkable for their large eyes, and 
which have no apparent neck, but whose transversal head is sepa- 
rated from the thorax by a strangulation. 
They live on the shores of ponds, &c. where they run with great 
swiftness, and frequently make little leaps. 
Some have a short and arcuated rostrum, and setaceous antenne. 
They form the 
Leptorus, Lat.(5) 
(1) The thorax in Nabis is not (or but very slightly) divided by that impressed 
and transverse line which we observe in Reduvius. Here, besides, the simple 
eyes are situated on an eminence or division of the posterior part of the head. 
This latter genus is susceptible of being separated into several’ subgenera,
