Wings rudimentary. Head and thorax brassy green, slightly 

 coppery, the former large, with a roughish fovea on each side en- 

 closing an elevated space on the crown very smooth, shining and 

 coppery; eyes large and prominent; mandibles and antennae 

 reddish, three joints at the base of the latter together with the 

 palpi testaceous. Thorax heart-shaped, in front broad from 

 angle to angle, thence gradually rounded and narrowed towards 

 the base, where it becomes much contracted, posterior angles 

 small and acutely elevated, the extremities of the base being 

 sloped towards them, disk convex, with an impressed central 

 furrow, the surface on each side faintly reticulated and very 

 minutely wrinkled throughout, the entire base depressed and 

 somewhat rugose. Elytra elongate, sides parallel, apex obtuse, 

 disk rather depressed, finely but distinctly striated, the striae 

 entire and very obscurely punctured, the third interstice with 

 four deeper impressions, yellowish testaceous at the base and on 

 the margins, with an obscure metallic fuscous cloud behind ex- 

 tending more or less upwards ; underside brassy black, legs pale 

 testaceous. Length 1J line. 



This species is recognized by its elongate and parallel form, 

 its short moniliform antennae and prominent mandibles. It is a 

 local species, but occurs in great profusion near Liverpool and 

 on the sands by the Chesil beach in the Isle of Portland when 

 the tide is out. It is likewise found on the shores of the Firth 

 of Forth sparingly, and in abundance on the shores of the Clyde 

 at Kilpatrick, as well as on the eastern coast of Ireland.
