(&.) Spiracula of tlie basal ventral segment not hidden by the 

 posterior part of the metastethium, sides of the basal segment scarcely 

 sliorter than those of the second segment. 



Stal makes the following sub-divisions of the Asiatic species : — 

 Tarsi 3-jointed : antenn® 4-jointed, second joint shorter than the 

 two apical taken together : apical margin of corium straight or some- 

 what roiinded : membrane at the base with several areolas emitting 

 longitudinal veins ; hamus usually distinct ; primary and subtended 

 veins entirely distant : segments of abdomen single. 



I. Metastei'num much elevated and freely produced forwards : 

 scutellum distinctly produced behind the frena, produced part triangu- 

 lar or spoon-shaped : thorax more or less produced hindwards at base 

 in the middle before the scutellum : — Div. Tessaratomaria. 



II. Metasternum simple or elevated, never freely produced for- 

 wards : scutellum equilateral, narrowly and slightly produced at the 

 apex behind the frena, rounded or truncated at the apex : thorax not 

 produced posteriorly : — Div. E usiJienaria. 



The other divisions are Oncomeraria chiefly from Australia ; Pri- 

 onogastraria and Uydogastrai-ia from Africa. 



Div. Tessaeatomaeia. 

 Genus Bmbolosteena, Stal.

Allied to Tessaratoma Serv., differs in having the head more acute, 

 perpendicular ; eyes larger, ocelli nearer the eyes : lateral angles of 

 pronotum cornuted, anterior lateral margins not flattened out, and apical 

 part of scutellum broader. Body large, obovate ; head perpendicular, 

 small, triangular, narrow at apex, subacute ; lateral margins somewhat 

 straight, juga much longer than the short tylus and contiguous before it ; 

 bucoulaa much elevated ; eyes large, transverse ; ocelli very close to the 

 eyes : antennte short, somewhat slender, first joint on a level with the 

 apex of the head, second joint a little longer than the third, and some- 

 what shorter than the fourth : pronotum much declined before the middle, 

 posteriorly amplified and produced hindwards, lateral angles produced 

 outward in a depressed horn, anterior lateral margins somewhat straight,
