 each side : eyes black : thorax glossy ferruginous, smooth, with a slender 

 dorsal line, and a small fovea near the base on each side : elytra rather paler 

 than the thorax, with five distinctly punctate abbreviated strife on the disc of 

 each interiorly, the exterior margin very smooth, with a few impressed dots, 

 at the base : body beneath glossy rusty-piceous : legs and palpi pale testaceous :

Found occasionally on the coast of Norfolk^ " On the shores of 

 the Humber." — Wm. Spence, Esq. 



Genus LXIII. — Aepus, Leach. 



Palpi, maxiUary with the terminal joint shorter than the preceding, the infernal 

 with the last joint slender, external with the third joint longest, stout, clavate, 

 the terminal slender, attenuated ; labial with the two last joints nearly equal 

 in length, the terminal slender and attenuated, the preceding robust : labrum 

 bilobed : mandibles porrect, acutely dentate interiorly ; mentum slightly emar- 

 ginate, tridentate anteriorly. Antenna; with the basal joint naked : head broad, 

 ovate : eyes minute : thorax obcordate-truncate : elytra depressed, obsoletely 

 notched at the apex : wings none : tarsi very pubescent beneath, the anterior 

 with a curved spine on the penultimate joint below. 



The depressed form, porrect mandibles, obcordate-truncate 

 thorax, large head, and attenuated terminal joints of the palpi, 

 sufficiently discriminate this genus from the rest of the Harpalidse, 

 exclusively of its minute dimensions, which are the least of the 

 family.
