Wingless, pitchy brown, with the margins of the thorax tes- 

 taceous, palpi and antennae pale testaceous. Thorax subquadrate, 

 a little narrowed in front, sides very nearly parallel behind, 

 posterior angles obtuse, dorsal furrow very slender, base de- 

 pressed and furnished with a very shallow smooth fovea on each 

 side. Elytra oblong-ovate, narrowed before and behind, so that 

 the sides appear very much rounded and distinctly widest in the 

 middle, very finely striated, the third interstice with from three 

 to (sometimes) five impressions; legs pale testaceous. Length 

 3^ lines. 



Its smaller size and more quadrate thorax, with obtuse hinder 

 angles, immediately distinguish this species from smaller examples 

 offuscus. * 



A very abundant species on sandy commons near the coast in 

 England, Scotland and Ireland.

 subquadrato, antice angustato, basi utrinque leviter im- 

 presso, angulis posticis obtusis ; elytris ovatis } subtiliter 

 striatis punctisque tribus impressis ; antennis pedibusque 

 testaceis.
