the eyes : scutellum wanting : body oblong, hard : elytra oblong-ovate, united, 

 the shoulders slightly prominent : femora slightly clavate, dentate : tibiae 

 obliquely truncate at the apex, and furnished with a stout hook within. 



Plinthus lias the body oblong, glabrous, hard, and apterous : the 

 elytra are united, scutellum wanting, the tibiae furnished at the 

 apex with a stout hook, the antennae with the club short, &c., by 

 which characters it may be known from the two preceding and the 

 following genera : — in the indigenous species the elytra are deeply 

 punctured, the punctures divided by elevated lines, which produce 

 a net-like appearance. 



Sp. 1. cahginosus. Fuscus, thorace varioloso carinato, elytris striis elevatis, 

 punctis inter strias impressis. (Long. corp. 4g — 5 lin.)
