Capt. P. P. Kine’s South American Coleoptera. 193 
Piceous: 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 antenne 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.

ruginous margin, a channel down the back, simple foveæ at the hinder
