(i£ the Continental authors had been seen by me, or the identity of their 

 insects with Hope's species had been suspected. This definition adds 

 a few particulars regarding the structure of the mouth-parts, tarsi, 

 presternum, etc. In the short basal joint of the tarsi and the flattened 

 subcylindrical body, Acanthocnemus approaches Felecoj^horus Latr., 

 Avhicli includes two or three species from Mauritius and Reunion ; but it 

 differs from that genus in the structure of the palpi, antennae, tibiae, 

 and tarsal claws, the bristly vestiture, and the deeply foveate pru- 

 sternum. The specimens assumed to be d have four visible joints only 

 to the anterior tarsi, a character common to several gen.era of Malachiids. 

 The revised synonymy and generic definition will stand thus : — ■

Head transverse, broad, the epistoma short, confused with the front ; 

 labruni short ; eyes large, entire; mandibles stout, dentate before the middle 

 within, feebly emarginate at the tip; terminal joint of tlie maxillary and labial 

 palpi narrow, subcylindrical, truncate at apex, the penultimate joint short; 

 antennae 11-jointed, stout, joint 1 very stout, 2-11 perfoliate, '2 and 3 obconic, 

 4-8 submoniliform, transverse, 9-11 much stouter than those preceding-, 

 together forming a loose club ; prothorax transverse, sharply margined at sides 

 and base ; scutellum strongly transverse ; elytra long, flattened, subparallel, 

 with numerous rows of punctures, the epipleura reaching as far as the apex of 

 the luetasternum ; prosternum with a deep, almost circular, flat-bottomed fovea 

 on each flank exterior to the sinuous transverse ridge closing the anterior coxal 

 cavities in front, the cavities themselves widely open behind, and the coxae 

 contiguous; five ventral segments exposed ; tibiae asperate, subdenticulate on 

 their outer edge, the spui's short; tarsi simple, 5-jointed, 1 short, wanting or 

 fused with 2 on anterior pair in c?, 5 long, the claws long, simple ; body sub- 

 cjdindrical, hairy, the hairs forming a close fringe along the elytral margins, 

 the antennae and tibiae setose.
