" as long as the rest of the thorax." I have compared the speci- 

 mens with those in the B. M. collection, and the determination is 

 quite certain. It is an extremely widely spread species.

$ . Head with the frontal area sparsely and shallowly 

 punctured, vertex and pronotum almost impunctate; mesonotum 

 with a few large and sparse punctures ; mesopleurae somewhat 

 sparsely punctured; abdomen impunctate. Clypeus with a very 

 conspicuous central longitudinal carina, which makes it appear 

 almost rostrate when viewed sideways, this carina produced back- 

 ward to the anterior ocellus ; besides the central carina there are 

 two other carinae, which, starting behind the anterior ocellus, lead 

 towards the base of the antennae, becoming more pronounced as 

 they near the latter. Pronotum nearly half as long again as

 the segment not much narrower than the 2nd segment. 



Brilliant metallic blue, with greenish reflections, the metallic 

 colour continued to nearly the apex of the femora of all the legs,
