Long. 31, lat. 15 mm . 



Oblong, brassy green, moderately shining on the upper part, with 

 the lateral, sides of the prothorax cyaneous ; head broadly impressed 

 on the vertex, antennas blueish-black ; prothorax one-third broader 

 than long, irregularly and very slightly punctured, not grooved in the 

 centre but with a very slight, longitudinal depression and two narrow 

 punctures at the base, above she scutellum, outer sides depressed, 

 rounded, roughly foveated with the foveas golden ; scutellum very short 

 and bi-lobated ; elytra as broad as the prothorax at the base, slightly 

 ampliated from near the shoulders to about one-third of the length, 

 and narrowed from there towards the apex, the outer margin from 

 below the shoulder to about the middle is depressed and has a few, 

 moderately deep foveas ; the striation is very slight and consists of 

 series of fine punctures with the intervals not raised and more finely 

 punctured than the striae ; the underside is dark-blue with a greenish

 golden, the sides of the prothorax are clothed with a dense ochraceous 

 pubescence, as are also the sides of the abdominal segments ; legs 

 dark-blue with irregular, deep, golden punctures. 



This splendid insect, the underside of which is almost as brilliant
