SCUTATINA. 15 



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

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

 Legs short ; tibia : first pair angulated ; tarsi trimerous. * . A 



Abdomen. Connexivnm narrow. Genital segments : in the $ , the first 

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

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

 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 . Podops. 



FAMILY ?. PENTATOMnm 



Head quadrangular, semi-elliptic, or subtrapezoidal. Rostrum 

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

 sometimes stout at the base; rostral channel shallow. Antennas 

 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: Mesosternum mostly with a slight keel. 

 Legs unarmed ; tibia 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 that 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, Eysarcoris ; 2, Pentatoma ; 3, 

 Strackia. 



FAMILY 8. ASOPIDJB. 



Head subquadrangular. Rostrum reaching to or beyond the second 

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

 shallow. Antennas slender ; tubercle short, inserted before the eyes. 

 Eyes 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 ; tibia 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 Pentatomida. Gen. 1, Zicrona ; 2, 

 Jalla ; 3, Rhacognathus ; 4, Asopus ; 5, Picromerus.
