long infuscate hairs and shorter yellowish ones, these latter of 

 different degrees of thickness, forming a frontal patch on the thorax, 

 and two narrow ones along the middle, one of which is close to the 

 base. 



Thorax about as broad as it is long, evenly convex, the base and 

 apex of nearly equal width, the former truncate, the surface coarsely, 

 closely, and deeply punctured. Elytra rather broader than the 

 middle of the thorax, not much longer than it, their sides curvate, 

 basal margin distinct ; they are coarsely striate-punctate, the third 

 interstices are a little raised, and, in some examples, bear two or 

 three yellowish spots, near the middle of the base the yellow hairs 

 sometimes form a large mark ; the scutellar region is depressed, and 

 there is a broad shallow impression near each shoulder. 



Underside dark, clothed with grey hairs, with coarse punctures ; 

 the fifth segment, however, and the sides of the basal four, are 

 nearly smooth. 



I have not been able as yet to distinguish the sexes in a satis- 

 factory manner.

Long., 12^mm. 



Head red, coarsely punctate and much pubescent. Antenna pale- 

 red, their basal portion much pubescent ; towards the apex the 

 pubescence becomes gradually less, and is wanting on the apical 

 joint. Thorax red, about as long as broad, the surface very uneven, 

 with a smooth longitudinal space on the middle, on each side of 

 which are coarse punctures ; this smooth space does not extend to 

 the front part, which is coarsely punctate ; on each side of the 

 middle towards the front there is a very distinct shining tubercle, 

 and externally to this a less distinct sublateral tubercle ; the angle 

 at the side behind the middle is very prominent ; the surface bears 

 much pale pubescence. Elytra shining, definitely and coarsely punc- 

 tate, and from each puncture there rises a pallid suberect hair ; 

 the punctuation is distant and regular ; along the side of the wing- 

 case, from the shoulder to the apex, extends a dark mark, and 

 across the surface stretch two transverse irregular fasciae of dark 

 colour ; the anterior one is angulate, and, as it proceeds from the 

 side to the suture, extends forwards, and along the suture extends 

 to the scutellum ; the posterior transverse fascia is broad and angu- 

 late, and sends a narrow 7 prolongation backwards along the suture 

 to the apex. The femora are red, and stout for this genus ; the
