16$ INSECTA. 



The remaining Geocorisae of this subdivision * have the rostrum 

 exposed, arcuated, or sometimes straip^ht; but their labrum is salient 

 and their head abruptly strans^ulated 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 



Reduvius, Fah. 



Their rostrum is short but sharp, and can inflict a severe punc- 

 ture, the painful effects of which are sensible for some time. Their 

 antennae are extremely slender near the end, or setaceous f . 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 : 



HoLOPTiLUs, Lepel. and Serv. 



Where the antennae have bvit three joints, the two last of which 

 are furnished with long hairs, arranged in two rows, and verticilated 

 on the last :J:. 



In the other species the antennae consist of four joints at least, and 

 are glabrous, or simply pubescent. 



Reduvius, Fah. 



Or Reduvii properly so called. The body is an oblong oval, and 

 the legs of a moderate length. 



We may unite Avith them the Nahis, Lit. § and the Pp.talocheires 

 of Palis, de Beauvois; the anterior tibiae of the latter are clypeiform. 

 R.personatus; Cimex personatus,lj.; Punaise mouc/ie, Geoff., 

 I, ix, 3. Lsngth 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 ||. 



Zelus, Fab., ' 



Where the body is linear, and the legs very long, extremely slen- 

 der, and alike ^. 



* The NudicoUes, Fam. Nat. du Regn. Anira. 



t 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.
