220 MODERN SYSTEM. 



Genus 26r. BLATTA. 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 numerous, and but little known : 

 much might be done towards elucidating this hitherto neglected part 

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

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

 genera and species." 



Order \ll. HEMIPTE;RA. 



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



Class Rhyngota. Fahr. 



Order Hemiptera. Section I. Heteropfera. Latr. 



Characters of the Order. 



JRostriim attached to the anterior extremity of the head : elytra some- 

 what crustaceous or coriaceous, with the apex membranaceous, 

 placed in an horizontal direction, one decussating the other : thoi-ax 

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

 ing one : haudellum with three seta : ocelli or little eyes two, one 

 obsolete. (^Metamorphosis semicomplete.) 



Section T. TERRESTRLi. Latr., Leach. 



The insects which compose this section are not only distinguished 

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

 ture of some essential organs : the antenna of this division are ex^ 

 sertetl, and are very distinct. 



Fam. I. Pentatomidje. Leach. 



Cor 1 51.1. 1. Latreille. 



^«fe««<c composed of five joints: rostrum wjth four distinct joints, the 

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

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

 mersed even to the eyes in the thorax. 



Stirps 1. — Scutellum elongate, covering the elytra and the wings. 



Genus 268. TETYRA. Fahr., Leach. Scutellera. Latr. Ci- 

 MEX. Linn. 

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

 //to/ar very narrow in front: antenna with the second joint longer 

 than the third.
