Length 30,5 mm., breadth at the shoulders 10 mm. — 

 Black, covered with a reddish brown pubescence which is 

 very dense round the eyes and forms two slightly diverging 

 vittae on the vertex ; on the prouotum the pubescence forms 

 a broad band along the middle and a narrow stripe on 

 each side ; on the scutellum it is divided along the middle 

 by a smooth stripe ; the elytra are speckled with small 

 spots of a dense reddish brown pubescence and marked, 

 just behind the middle, with a large oblique velvet-black 

 patch which is broader anteriorly than posteriorly and 

 here more approximate to the suture than to the lateral 

 margin ; in front of and behind this black patch the 

 pubescence is of a paler colour and on both sides of the 

 scutellum there is a similarly coloured short, slightly obli- 

 que basal stripe ; the basal joint of the antennae is covered 

 with a thin greyish brown pubescence, the 3rd and follow- 

 ing joints have a dense grey pubescence and are ringed 

 with sooty black on their apical portion. 



The head shows some punctures on the face, behind the 

 upper lobes of the eyes and on the middle of the vertex; 

 the scape of the antennae is slightly rugose and strongly 

 narrowed towards the base.
