 exterior to these with the vestiges of other abbreviated or broken 

 striae, the fourth of which has an impression in front, the sides 

 and apex smooth ; legs testaceous. Length f line. 



Scarce, but found occasionally on the coast of South Wales ; 

 at Hyde, and on a broken sandy undercliif between Luccombe 

 and Shanklin, Isle of Wight.

Head and thorax pitchy black, sometimes obscurely brassy, 

 base of the antennae testaceous. Thorax transverse, broad, sides 

 dilated and rounded, scarcely narrowed behind, but with the base 

 almost as wide as the anterior margin, posterior angles obtuse 

 but elevated, disk convex, very smooth and shining, dorsal furrow 

 slender, base narrowly depressed and furnished with two deep 

 foveae close to the hinder margin. Elytra oblong-ovate, broader 

 than the thorax, convex, punctate- striated, one or two striae 

 nearest the suture carried to the apex, the others abbreviated 

 before the apex, which exterior to these is smooth, the lateral 

 striae likewise very obsolete, the third interstice has two impres- 

 sions, the surface is entirely pitchy black, sometimes with an 

 obscure greenish or bluish tinge and not unfrequently more or 

 less pitchy rust-colour, perhaps the result of a less degree of 

 maturity ; legs red with the femora generally pitchy. Length 



Tachys immunis, pusillus and gracilis, Steph., belong to this 

 species ; the latter is a smaller example. It is generally distributed.
