Oblong, wingless, depressed, pitchy black, sometimes with a 

 rusty hue. Head large, flattened, with two deep longitudinal 

 frontal furrows; antennae long, and, together with the palpi, 

 rusty red. Thorax heart-shaped, wider than the head, sides 

 rounded below the anterior angles, much contracted behind, 

 posterior angles rather acute, base with two deeply impressed 

 fovese. Elytra rounded off at the shoulders, the sides almost 

 parallel, disk depressed, deeply striated, the striae deepest next 

 the suture, all of them entire, with some of the marginal ones 

 distinctly though finely punctured, the interstice between the 

 third and fourth striae furnished with two deep impressions, one 

 about the centre and the other nearer the apex ; legs red. 

 Length 2 lines. 



This species is rare; in 18456 I found it in some abundance 

 among the fine shingle on the sea-beach at Ventnor and Steep - 

 hill, Isle of Wight ; since which time it had not occurred till 

 1852, when Mr. Guyon again procured it in the last-named 

 locality. M. Chaudoir found it in the Crimea ; and it is not a 

 little remarkable that it has been discovered only in these two 

 localities, so widely remote from each other.
