humerus, are perceptibly raised ; there is an impunctate marginal

red-brown with the greater portion of the basal half black, this 

 latter colour extending longitudinally and broadly to the front 

 margin ; scutellum black; each elytron largely black with the fol- 

 lowing yellow-brown or red-brown markings : (1) between the 

 scutellum and the humerus one large patch, (2) part of the surface 

 round the anterior lateral angles, (3) an irregular, narrow and 

 transverse post-median band, (4) nearer the suture on the 

 apical part of the surface one small round spot, and (5) finally a 

 smaller area at the external apical angle. Underside generally 

 black abdominal sternites partly so, and an area along the sides 

 of the prothoracic sternum, with the epipleura, yellow-brown or 

 red-brown, the legs sharing this latter colour. The whole insect 

 may be conceived as having brown as the ground-colour and black 

 as' secondary, but the latter predominates fco such an extent that 

 the opposite may be the true colour-scheme.
