Variable in colour, usually brownish brass, sometimes greenish 

 or bluish black. Head smooth, with a transverse ridge in front 

 and an impression on each side, palpi and antennae red. Thorax 

 truncate in front, sides very much rounded and dilated before 

 the middle and contracted behind, globose and shining, with a 

 slight dorsal line, but without basal fovese, base with a narrow 

 depresed neck remote from the elytra, and furnished with a few 

 punctures on the sides. Elytra ovate, with the shoulders 

 rounded, dilated behind the middle, very convex and shining, 

 having a few irregular more or less obsolete punctured stria3 

 near the suture, which vanish towards the extremity, and a 

 scarcely punctured one next the margin, which is continued to 

 the apex, the margin itself being sometimes narrowly edged 

 with red ; body beneath blue-black, apex of the abdomen rufous, 

 legs short and wholly red. Length 3 lines. 



This species was first described by Eschscholtz, in the ' Bul- 

 letin de la Societe Imperiale des Naturalistes de Moscou/ in 

 1830. It is very local and nowhere abundant. It is found 

 upon some of the high moors in Derbyshire, Yorkshire, and in 

 Scotland. I have taken it also on the mountains near Llangollen 

 in North Wales, in August.
