Head smooth and shining, vertex very minutely punctm-ed, encarpne oblique 

 well defined, quadrangular, nearly contiguous at their apices ; clypeus smooth, im- 

 punctate, trigonate ; antennae longer than the thorax, only moderately thickened, the 

 two lower joints pitchy, the apical one white. Thorax nearly three times as broad 

 as long, basal margin oblique on either side, broadly and obtusely rounded in the 

 middle ; sides obliquely converging, hinder angles obtuse, the anterior rounded, 

 thickened ; surface remotely punctured. Scutellum large, trigonate. Elytra broader 

 than the thorax, shoulders obsolete ; above distinctly punctured, each with five small 

 black spots, two at the base (the outer one close to the scutellum, the other on the 

 humeral cellus), two placed transversely across the middle, and one between the 

 middle and the apex, but rather nearer the latter ; inflexed margin concave, its outer 

 edge only slightly produced.

This genus, nearly allied to (Edicerus, is remarkable for tbe sin- 

 gular structure of the antenuic in the male ; these organs apparently 

 consist of ten joints, the eighth being very long and armed at the base 

 with a slender perpendicular spine, which nearly equals in length the 

 joint itself ; on closer examination, however, it will be seen tliat the 

 antennae are really eleven-jointed, the body of the true eighth joint 

 (from the outer apex of which springs the slender spine) being very 

 short, and almost entirely concealed in the hollow apex of the seventh. 

 I do not know the female, but that sex probably has simple antennae 

 as in QSdicerus.

 nigris, his articuUs duobus ultimis albidis ; elytris violuceo-purpu-
