 (sicut granuloso), foveola perparva medio impresso ; thorace basi paullo angustato, crebre punctato, haud

The thorax has the two impressions on the disc very well marked, the front one 

 very small, the posterior one larger and round ; the posterior ridge is very distinct, 

 directed obliquely inwards. The elytra have the subcosta fairly well marked, but very 

 obtuse ; the sutural region has indications of two very slight impressions, one before, 

 the other behind the middle. The prosternal chin-piece is slightly but distinctly 

 emarginate. The presternum is finely punctured, shining, the punctures not crowded 

 together. The metathoracic episterna are sparsely clothed with white pubescence. 

 The abdomen is moderately strongly punctured, the punctures net crowded, generally 

 united transversely by fine striolse. 



One example has the head obscure green in front.

The head is densely and extremely finely rugose, and with some rather strong and 

 moderately close punctuation ; the upper part of the face has some longitudinal lines ; 

 the top of the head is dark purple ; the upper part of the face is dark steel-blue, below 

 which there is a transverse coppery-red line ; the clypeus is golden-green ; there is an 

 impressed line down the middle of the face. The thorax is dark purple (or dark green) 

 in front, coppery-red at the base ; the surface is covered with curved, undulating, im- 

 pressed, punctured lines ; the posterior ridge is well marked and sharp, nearly straight, and 

 not; curved down anteriorly to meet the margin. The elytra have the subcosta moderately 

 well marked ; the surface is closely asperate, caused by the transverse dentate impressed 

 striolse. The presternum is closely punctured, slightly pubescent. The metasternum
