SCUTATINA. . 15 



men, very wide throughout, sides parallel, end broadly rounded. 

 Sternum without rostral chanuel, only widely depressed in the centre. 

 Legs short ; tihiw : first pair angulated ; tarsi trimerous. 



Abdomen. — Connexicum narrow. Genital segments : in the $ , the fii'st, 

 segment vertical, hiudwardly, at each side, with a broad, sinuate process, 

 projecting beyond the base, curving inwardly, but not meeting in tlic 

 centre. In the 9, the first segment is short ; the second forms two long, 

 widely separated, triangular plates; the third is triangular, filling the 

 space between the plates of the second segment, and hindwardly projecting 

 beyond them, the posterior margin rounded. Gen. 1. Fodops. 



Family 7.— PENTATOMIDtE. 



Head quadrangular, semi-elliptic, or sub trapezoidal. Rostrum 

 reaching at least to the second pair of coxse, generally slender, 

 sometimes stout at the base ; rostral channel shallow. Antennce 

 slender, short or long. Pronotum hexangular, hinder angles some- 

 times much produced. Scutellum subtriangular, broad, generally 

 constricted beyond the middle. Sternum without, or only with a 

 shallow, rostral channel: llesosternum mostly with a slight keel. 

 Legs unarmed ; tibice generally with the margins of the upper side 

 reflexed, forming a channel ; tarsi trimerous. 



Abdomen. — Genital segments : in the $ the single segment on the pos- 

 terior margin is either straight or notched in the centre, so tiiat the 

 angles are somewhat pointed. In the $, the first segment is generally 

 convex ; the second appears under its posterior margin ; the plates of the 

 third segment are long and divided, the obtuse points generally projecting 

 a little beyond the abdomen. Gen. 1, Ej/sarcoris ; 2, Pentatoma ; 3, 

 StracJiia. 



Family 8— ASOPIDJE. 



Head sub quadrangular. Rostrum reaching to or beyond the second 

 pair of coxae, stout, the base very broad ; rostral channel short and 

 shallow. An.tenncB slender ; tubercle short, inserted before the eyes. 

 Eges moderate, or large and prominent. Pronotum hexagonal, fre- 

 quently much produced at the hinder angles. Scutellum triangular, 

 sides sinuate, apex rounded. Sternum with a slight keel. Legs : fore 

 thighs sometimes, with a spine beneath ; tilncB outwardly flattened, 

 the margins on the upper side (of the fore pair especially) reflexed ; 

 on the under side a fine, acute spine ; tarsi trimerous. 



Abdomen. — Genital segments as in Pentatoinidte. Gen. 1, Zicrona ; 2, 

 Jalla ; 2>, Bhacognathus ; 4,Asop/is; 5, Picromerus.
