{d.) Tarsi 2-jointed : scutellum not reaching the middle of tlie 

 dorsum of the abdomen, generally very narrow at the apex ; and fur- 

 nished with frena extended almost to the apex : tibise obtusely rounded, 

 rarely furrowed. It contains those genera of the family Pentatomidm 

 of Dallas which have the scutellum triangular, subequilateral, or not 

 much longer than broad, not reaching or barely extending beyond the 

 middle of the dorsum of the abdomen, the apical part placed behind the 

 frena, generally small, short, and narrow, the frena generally extended 

 for a distance towards the apex of the scutellum, rarely reaching only 

 the middle of the scutellum, apical margin of corium straight, rarely 

 rounded towards the exterior apical angle, tibiaj obtusely rounded 

 and the sixth ventral segment, in $ , rather strongly sinuated at the 

 apex in the middle before the genital valvules.

Body elongate-ovate : head large, broad, gradually sinuately 

 narrowed behind the middle, sides anteriorly parallel or barely diverg- 

 ing, apex broadly and obtusely rounded, tylus and juga subequal in 

 length : antennsB S-jointed, basal joint short and stout, not extending 

 beyond the apex of the head, second joint minute, third joint largest, 

 nearly as long as the two following taken together, fourth longer than 

 the fifth : rostrum rather long, reaching the base of the ventral spine ; 

 2 and 3 joints about equal, the fourth shorter, basal joint half concealed 

 within the head : pronotum anteriorly and sides distinctly margined, 

 margins narrowly elevated and smooth, unarmed : scutellum rather 

 small, longer than broad ; frena not extending beyond the middle of 

 the scutellum : membrane with longitudinal veins : mesostethial lamina 

 reaching the head : sixth ventral segment, in 9 , furnished, towards the
