Rather small insects having a tooth just in front of the lateral 

 pronotal angles which thus appear emarginate. 



Podops Laporte.

 notal angles produced in an acute tooth near the eyes.

Key to Tribes. 



1. Body very flat, margins explanate ; head with thin dilated margin, 



about as wide as base of scutellum, flat above; scutellum broad, 



scarcely narrowed apically Sciocorini 



Body not extremely flat and explanate ; head not very widely 

 dilated, convex above when as wide as scutellum, usually narrower 2 



2. Juga in Nearctic species with a prominent lateral tooth near apex ; 



abdomen shallowly sulcate beneath, rostrum extending behind 



posterior coxae Halyini 



Juga without lateral tooth; abdomen not sulcate, rostrum shorter 



Pentatomini 



Tribe SCIOCORINI. 



The species of this group have a peculiar and easily recognizable 

 facies. A single Palaearctic species is rarely found in the eastern 

 states.
