Oblong, depressed, sides sub-parallel. 



Head porrected, (including the eyes) not so wide as the pronotum, 

 middle lobe short, yet longer than the side lobes, the ends of the 

 rostral channel projecting beyond its apex. Antennce slender ; 

 tubercle large, distinct; 1st joint stoutest, long, three-fourths the 

 length of the head, more than one-half its length reaching beyond 

 the apex of the face ; 2nd one-third longer than the 1st; 3rd ra- 

 ther longer than the 1st ; 4th wanting. Eyes moderate, projecting 

 a little, inserted close to but not touching the pronotum. Ocelli 

 small, distant, on the posterior margin of the head near the eyes. 

 nostrum reaching to the 2nd pair of coxae, 1st joint not quite ao 

 long as the head, 2nd and 3rd sub-equal, each a little longer than 

 the 1st, 4th sub-equal with the 1st. 



Thorax — Pronotum transverse, the breadth rather more than the length, 

 slightly convex, more so in front ; sides straight, margins hardly 

 perceptible, anterior angles rounded ; anterior and posterior mar- 

 gins straight. Scutellum long- triangular, flat. Elytra scarcely so 

 long as the abdomen, depressed aloug the region of the claval su- 

 ture : Corium outwardly deflected : Membrane short. Sternum — 

 mesosternum xyphus short, triangular, depressed in the centre ; 

 we^fls^erwwTW xyphus longer, with a middle keel. Legs— Ist pair, 

 thiffhs moderately incrassated, beneath with a channel on the an- 

 terior half, of which the inner edge has three contiguous spines, 

 the 1st short, the other two long and thin throughout : tibics with 

 distant fine spines, the 1st pair (which are straight) on the under- 

 side only: tarsi long, slender; 1st joint on the 1st and 2nd pairs 

 longer than the 2nd and 3rd joints together, on the 3rd pair twice 

 as long; 2nd and 3rd joints in length sub-equal. 



This genus has a gresit prima facie resemblance to Calathus {Coleop- 

 tera) ; its affinities seem nearest to our new genus Lamproplax.
