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 bey(md 
the apex of the face ; 2nd one-third longer than the 1st; 8rd 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 postei-ior margin of the head near the eyes. 
Bostrum reaching to the 2nd pair of coxse, 1st joint not quite so i 
long as the head, 2nd and 3rd sub-equal, each a little longer than i 
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 along the region of the claval su- 
ture : Corium outwardly deflected : Membrane short. Sternum — 
mesosternum xyphus short, triangular, depressed in the centre ; 
metasternum xyphus longer, with a middle keel. Legs —1st pair, 
thighs 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 : tibice with ^ 
distant fine spines, the 1st pair (which are straight) on the under- J 
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 greiit prima facie resemblance to Calathus (Coleop- , 
tera) ; its aflB.nities seem nearest to our new genus Lamproplax.
