Thorax. Pronotum black in front, more or less luteous behind, 

 on the posterior half a central fine, lighter, longitudinal line, and 

 sometimes on each side of this another similar, but ill defined; 

 sides coarsely punctured ; broadly incrassated, the incrassated portion 

 widest in front, bounded inwardly by a deep, narrow, longitudinal, 

 bent channel, in the middle of which is a deep fovea ; on the anterior 

 third of the disk two transverse, lobate, scarcely raised, black spaces, 

 of which the apex does not reach the centre, and the base rests upon 

 the longitudinal channel. Scutellum luteous, more or less variegated 

 with small black marks, the punctures wider apart than on the 

 pronotum, the base usually black, towards the sides with a deep 

 fovea ; in the centre a narrow, pale luteous line extends nearly the 

 whole length, wider before its termination, and then bordered on 

 each side with a short, thick, black line ; half way between the cen- 

 tral line and the side, a thick, black line extends from the base to 

 beyond the middle, ceasing abruptly ; this line is generally bordered 

 with pale luteous, but it is sometimes broken into two or three 

 pieces ; sometimes the ground colour of the scutellum is luteous 

 almost without markings, at other times a piceous shade prevails.
