Long. 11 mm., elytr. 8, lat. 4i. 



Derm brown, densely covered with a white pubescence, which is faintl}- tinged 

 with greenish bniF, chiefly on the antennae and tarsi. Head wanting tlie white 

 pubescence in the iiiiiklle of the vertex immediately in front of the protliorax. 

 Antennae black, about a fifth longer than the body. Anterior transverse groove 

 of the prothorax very distinct, even on the upperside, and the basal one still 

 stronger ; of the three longitudinal brown streaks the median one is broad and 

 narrowed at the base, while the lateral ones are narrow. Scntellum much broader 

 than long, almost of the shape of a trapezium, and clothed with sparse white hairs. 

 Each elytron bears some brown markings : one standing behind the scntellum, 

 of a short linear shape ; a second also linear, extending from the shoulder beyond 

 the middle of the elytra, and sligiitly flesuose ; a third linear, but short, placed near 

 the suture in front of the middle ; and three or four irregular spots, small and placed 

 between apex and middle of the elytra. Pnbescence of the under surface much 

 sparser than that of the upperside, so that the colour of the derm shows through, 

 especially in the middle. Legs tawny, with the tarsi somewhat darker. Meso- 

 sternum vertically precipitous, somewhat elevated, and with the margin rounded.
