Division SOUTELLERARIA. 

 Sciitelleraria, Stal, E7i. Kem. id, p. 3 (]873). 



Body beneath distinctly convex. Meso- and metasterna without 

 wrinkles or ridges, sometimes furrowed. Thorax and scutellum 

 with their bases more or less convexly inclined, the first hindwardly, 

 the second forwardly, the convexity principally visible from the 

 side ; pronotum distinctly truncated posteriorly before the base of 

 the scutellum, basal angles generally very distinct. Second joint 

 of rostrum generally shorter, and often much shorter, than the two 

 apical joints taken together. 



This division of the Scutellerinae is distributed throughout all 

 the warmer regions of the earth and is largely represented in this 

 fauna.
