Dark grayish-browii ; head yellowish, the two middle 

 carinse approximate, brown; prothorax rather abruptly 

 rounded towards the base, and contracted, especially in 

 $ , yellowish, the disc with three large oblong dark brown 

 spots, the middle one extending from near the apex to 

 the base, the lateral ones rounded, and a little nearer the 

 apex than the base ; scutellum semicircular ; elytra with 

 five yellowish bands, the second and third united at the 

 suture, the former curving outwards and backwards, the 

 fifth apical and somewhat oblique ; body beneath yellow-

 two median very short, united nearly throughout.
