exception of the palpi, which, together with joints 1 and 2 of the 

 antenna3, are yellowish ; joint 3 of the maxillary palpi, however, 

 is of the general colour of the mouth. The labrum is square 

 and entire; the 2nd antennal joint is rather shorter than the 

 rest. The thorax is transversely ovate — that is to say, its greatest 

 width is at the middle — not, as in a cordate thorax, before it ; the 

 fovea? are connected by a series of punctures, which gradually 

 deepen towards the centre; the longitudinal divisional line is 

 also deeper at the apical extremity than at the other parts. The 

 elytra are impressed with seven deep furrows on either side, 

 deeply punctured at the bottom ; these furrows decrease in 

 length towards the margin, and in depth towards the apex, with 

 the exception, however, of the first on either side, which goes 

 straight down to the apex. At the latter comparatively smooth 

 place is the semicircular impression noticed in the three pre- 

 ceding species, and to be noticed in all the following. The base 

 of the elytra is smooth. No traces of punctures, such as are 

 usual in the region of the 3rd or 4th interstice, are observable. 

 The lower side of the insect is of a pitch-colour ; the basal part of 

 the legs and thighs are lighter, and the tibiae and tarsi very light.

Very closely allied to the preceding species, and equally pretty. 

 Head and thorax entirely those of the former; the antennae, 

 however, are more filiform, and the divisional line of the thorax 

 is not deepened at the apical extremity. The elytra are smooth, 

 with only two striae along the suture on either side, the rest not 

 being even traceable; both these striae are abbreviated at the 

 base, and the outer one becomes obsolete towards the apex ; the 

 inner one, however, goes fully down to the apex, and falls in 

 with a deep inframarginal furrow, which is wanting in the pre- 

 ceding species ; before and beyond the middle is a small im- 

 pression ; before the apex are two oval spots of orange-colour ; 

 the apex has the semicircular impression noticed in the preceding 

 species.
