220 MODERiV SYSTEM. 



Genus 267. BLA TTA. Linn., Fabr., S,c. 

 Sp. 1. 



" The genus Blatta may be defined (as it now stands), to be a ge- 

 neral reservoir for all insects agreeing with the character of the 

 Order. The foreign species are niuiierous, and but little known : 

 much might be done towards elucidating this hitherto neglected part 

 of entomology, and it is hoped some cntomographer who has time 

 will devote some share of his attention to the examination of the 

 genera and species." 



Order VII. HEMIPTERA. 



Order Hemiptera. Linn., Lam., Cuv., Leach. 



Class Rhyngota. Fab?-. 



Order IIemiptera. Section I. Heteroptera. Lutr. 



Characters of the Order. 



Roifrum attached to the anterior extremity of the head : eli/tra some- 

 what crustaceous or coriaceous, with the apex membranaceous, 

 placed in an horizontal direction, one decussating the other : thorax 

 with the first segment (which bears the feet) larger than the follow- 

 ing one : haustellum with three setae : ocelli or little eyes two, one 

 oT^olete. {Metamorphosis semicomplete.) 



Section I. TERRFSTmA. Latr., Leach. 



Tlie insects which compose this section are not only distinguished 

 from the second section by their economy, hut likewise by the struc- 

 ture of some essential organs : the antenna of this division are cx- 

 serted, and are very distinct. 



Fam. I. PentaTomid^. Leach. 



CoRiSi.?: I. Latreille. 



^j!«c«»fF composed of five joints: ros^/-u?« with four distinct joints, the 

 three first of nearly an equal length : lubrum very long, striated : tarsi 

 with three distinct joints, the lirst elongate : head trigonate, im- 

 mersed even to the eyes in the thorax. 



Stirps 1. — Scutelhan elongate, covering the elytra and tlie wings. 



Genus 268. TETYRA. Fabr., Leach. Scutellera. Latr. Cx- 



MEX. Linn. 

 Scutellum longer than broad, not covering the sides of the abdomen : 

 thora r very narrow in front : antenncc with the second joint longer 

 than the third.
