the compressed sides, both above and below, nearly to the end of 

 the last joint. Head smooth and polished. Labrum with a row 

 of large punctures (from which spring hairs) in front. Mandibles 

 with a bisinuated keel, broadest in the middle, running along the 

 upper side. A narrow marginal ridge runs along each side of the 

 head until it reaches behind the eye. The two frontal impressions 

 are sinuate, each composed of two deep lines which meet in front 

 and extend in a sinuate manner backwards, diverging gradually 

 from each other ; they are joined in front by a straight trans- 

 verse line : all these lines are impunctate. Head behind smooth 

 and convex. The thorax is subquadrate, and has somewhat th ^ 

 form (in miniature) of that of some species of Pasimachus (e. g. 

 P. sublcevis, Beauv.) ; it is smooth, shining, and impunctate ; 

 the dorsal median line is faint, and reaches neither to the front 

 nor base ; the two foveated lines at the base are placed nearly raid- 

 way between the median line and the margin, but rather nearer 

 the middle ; they are long, deep, well defined and narrow, and at 

 their base turn off towards the sides at a right angle, forming a 

 narrow ridge on the exterior portion of the base of the thorax, 

 which is wanting in the centre, and which continues along the 

 lateral margins round to and past the anterior angles, and a 

 considerable distance along the anterior margin, but fades away 

 before reaching its middle. A deep channel thus runs along 

 parallel and close to the margins of the thorax. The prosternum 

 is rather broad, and slightly produced and expanded behind. 

 Near the termination of the expansion there is a sort of double 

 depression, which leaves a narrow raised margin. Scutellum im- 

 punctate, scarcely reaching to the part of the elytra where the 

 strise commence. Elytra smooth, shining, and impunctate, with 

 seven deep impunctate strise besides the marginal stria ; the strise 

 become deeper towards the apex ; there is no abbreviated sutural 

 stria. The first two strise run alongside up to the apex ; the third 

 and fourth join together a short distance from the apex, and 

 their united line goes on for a short distance ; the fifth and sixth 

 do the same ; the seventh runs the whole length, becoming wider 

 towards the apex, where one or two circular punctures or fovese 

 occur. The marginal stria has a number of these impressed on 

 it ; it runs up to the apex, where it widens much, and is divided 

 by a raised line, which proceeds from the emargination near the 

 apex. The marginal ridge of the elytra is rather broad and pro- 

 minent. A faint stria runs along the under margin of the re- 

 flexed edge of the elytra ; the interstices between the strise are 

 convex, but more so on the sides and towards the apex than at 

 the middle and base. The under side is smooth, polished, and 

 impunctate, except two minute punctures, one on each side of
