elytra sloped rapidly away, and, when on a level with the lateral 

 margins, extended downwards and forwards ; the retuse portion 

 is duller than the rest of the elytra, with the punctures larger, 

 is margined to within about a third of the suture on the ii)»j)er 

 part, with four teeth on each elytron, one near the suture, another 

 a little further on, and at the termination of the marginal rim, 

 both thick, and subacute, and two at the apex opposite to them, 

 flatter and less sharply pointed ; there is also on the under portion 

 of the apex of each elytron a sharp spine, extending downwards. 

 Undersurface of body pitchy, shining, very sparingly pubescent ; 

 the abdominal segments edged with testaceous, the apical ones 

 excavated, with, on each side of the excavation, a broad half- 

 raised shining lightly punctate semi-rounded plate, and in front 

 of it two long fiat reddish-testaceous bundles of hairs, appearing 

 like obtusely pointed spines. Legs testaceous, knees and trochan- 

 tins tinged with piceous. Length 5 J mm.

A PATE B I COLOR, n.sp."^ 



Elongate, cylindrical, shining and punctate. Head black, dull, 

 with a fovea in the centre. Thorax testaceous, darker in front 

 than behind, about as broad as long, rough and dentated in front, 

 with the anterior tooth recurved, behind and at the sides smooth, 

 shining and impunctate, and minutely hairy at the base. Elytra 

 pitchy, shining, the base tinged with testaceous, more than twice 

 as long as the thorax, shallowly and densely punctate, obliquely 

 truncated at about two-fifths from the apex ; the retuse portion 

 dull, slightly hairy, margined nearly all rouud, and punctate, 

 the punctures larger and coarser on the upper portion, entirely 

 disappearing towards the apex, and with two short projections 

 on each elytron, one near the suture, the other about the Scune 

 distance from it, at the termination of the marginal rim, slightly 

 longer and extending downwards and slightly inwards ; lateral 

 margins of the elytra wavy. Undersurface of body punctate,
