166 INSECTA, 
The remaining Geocorise of this subdivision* have the rostrum 
exposed, arcuated, or sometimes straight; but their labrum is salient 
and their head abruptly strangulated behind or narrowed into a neck. 
Certain species have remarkably large eyes. 
Those which do not present this character, and have their head 
supported by a neck, form the primitive genus 
Repvvivs, Fab. 
Their rostrum is short but sharp, and can inflict a severe punc- 
ture, the painful effects of which are sensible for some time. Their 
antennz are extremely slender near the end, or setaceous {. Several 
of the species make a noise similar to that which proceeds from 
the Crioceres, Cerambyci, &c., but which is produced with more 
rapidity. 
This genus has been thus divided : 
Ho.opriuus, Lepel. and Serv. 
Where the antennz have but three joints, the two last of which 
are furnished with long hairs, arranged in two rows, and verticilated 
on the last ¢. ; 
In the other species the antenne consist of four joints at least, and 
are glabrous, or simply pubescent. 
Repvvivs, 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 Nabis, Lat.§ and the Petalocheires 
of Palis. de Beauvois; the anterior tibie of the latter are clypeiform. 
R. personatus; Cimex personatus, L.; Punaise mouche, Geoff., 
I,ix,3. 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 
Zeus, Fab., 
Where the body is linear, and the legs very long, extremely slen- 
der, and alike 4. 
* The Nudicolles, Fam. Nat. du Régn. Anim. 
+ The first joint is frequently united to the second, and the latter to the third, by 
a very small joint or rotula.

§ 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 eyees 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.
