raised Y. Elytra flattened, greatly depressed about the region of 

 the claval suture : Gormm — the anterior margin, outside the first 

 nerve, beyond the first third, considerably widened and deflected ; 

 nerves strong : Membrane (in all the extant examples) abbreviated, 

 not covering the abdomen. Legs slender ; tliighs — 1st pair only 

 moderately incrassated, beneath, in the $ , anteriorly and out- 

 vsrardly with two very small, acute spines; in the (J these are 

 almost obsolete ; tihics with fine, short, projecting, spinose hairs : 

 1st pair straight, the hairs finer and shorter, and on the under-side 

 only ; ^«r*nong, slender; the 1st joint on the 1st pair of legs as 

 long, on the 2nd pair longer, on the 3rd pair much longer, than 

 the 2nd and 3rd joints together. 



This genus mostly resembles Drymus, Fieb., from which it differs 

 in the antennae being longer and more slender, the 1st joint much 

 longer and the others differing in their proportions, in the different 

 form of the pronotum, in the spines on the thighs of the ? only, in the 

 fore-tibiae being straight and furnished with hairs beneath, &c. 



Species 1. — LAMPEOisroTus Shaepi, Doug. Sf Scott (pi. 2, fig. 1). 



Black, shining ; pronotum anteriorly polished, sides delicately 

 ciliate ; elytra piceous, corium black inwardly and posteriorly ; legs

 apex pale testaceous. Rostrum piceous. 



Thorax — PronoUmn anteriorly glossy, unpunctured (except a row of punctures on 

 the anterior margin and sides) ; posterior portion deeply, roughly, and irregu- 

 larly punctured ; sides with delicate pale cilia ; side margins, posterior margin,

Dr. Sharp, the well-known coleopterist, to whom we have dedicated 

 the species, found one 3" ^^^^ two ? examples, last autumn, on the 

 shore of Dabton Loch, near Thornhill, Dumfriesshire, and kindly pre- 

 sented them to us.
