This beautiful specie.s is of a bright metallic blue colour %vith a 
narrow green margin to the prothorax and elytra. Head sub- 
quadrate (3 X 4i), narrowed behind the eyes which are prominent ; 
the frontal sulci diverging backwards, behind connected by a trans- 
verse impression extending behind the eyes ; two su]n’a-orbital 
punctures, and the usual frontal jjunctures near the clypeus; labrum 
short and truncate in front ; the px’ojecting teeth of the clypeus 
strong, between them the clypeus lightly emarginate in the middle. 
Prothorax transvei-se (3^ x 5), truncate in front, with the angles 
rather acute, margined, and very slightly advanced ; behind 
rounded ; the sides and base with a narrow reflexed margin, 
rather thicker on the base ; the ba.sal portion of the prothorax 
defined by a curved transverse line, rather elevated between 
this line and the margin ; the meilian line distinct, not reaching 
the anterior margin ; a short rather oblique transverse line at 
each anterior angle, and a faint impression on each side of the 
base ; two setigerous punctures on each margin, one near the 
anterior angle, the other at the place of the posterior angle. 
Elytra oval (9 x 5^), a little wider than the prothorax, somewhat 
convex, the upper surface being rather flat ; bipunctate towards 
the apex; the lateral margins narrow; the marginal channel rather 
deep, and closely set with punctures ; the sutui’e deeply marked ; 
the base obliquely declivous towards each humeral angle, and
