Capt. P. P. King's South American Coleoptera. 193 



Piceoiig : head and thorax blue-green or violaceous ; elytra bright green, 

 sometimes yellowish round the sides. Thorax cordate-quadrate, slightly 

 transverse, base not contracted, with a simple fovea near each angle, 

 which is not acute, a channel down the back ; elytra more than twice as 

 long as the thorax, scarcely broader and ovate, a sharp stria down each 

 side of the suture, the others punctate, but nearly obliterated, excepting 

 the 2 costal, on which there are deep punctures, a puncture near the base 

 of the 3rd stria, a 2nd below the middle, and another towards the apex : 

 palpi, base and apex of antennce and tarsi ferruginous. 



This handsome species from Conception has so much the habit of an Har- 

 palus, that if it were not for the tarsi I should have considered it as such. 

 The lobe of the mentum is emarginate.
