MOJJXRN SYSTEM. 
Genus 267 , BLATTA. Linn., Fabr., <§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, aud it is hoped some entomographer 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. Fabr. 
Order Hemiptera. Section I. Heteroptera. Latr. 
Characters of the Order. 
Rostrum 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 : thoras 
with the first segment (which bears the feet) larger than the follow- 
ing one : huustellum with three seta : ocelli or little eyes two, one 
obsolete. ( Metamorphosis semicomplete.) 
Section I. TERRESTRTA. 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 oi some essential organs i the antenna of this division are ex- 
serted, and are very distinct. 
Fam. I. Pentatomidae. Leach. 
Cokisi.e I. Latreille. 
Antenna composed of five joints: rostrum with four distinct joints, the 
three first of nearly an equal length : labrum very long, striated : tari‘ 
with three distinct joints, the first elongate : head trigonate, ii hr 
mersed even to the eyes in the thorax. 
Stirps 1 . — Scutellnm elongate, covering the elytra and the wings. 
Genus 268. TETYRA. Fabr., Leach. Scutellera. Latr. Cl' 
mex. Linn. 
Scutellnm longer than broad, not covering the sides of the abdomen : 
thorax very narrow in front: antenna with the second joint longer 
than the third.
