tei'ior nor basal fovcfp. Tlic elytra are as wide as tlie thorax, very 

 obtusely rounded and abruptly declivous at the tip, depressed on tlie 

 back and broadly rctuse-concave at tbe base, with projecting shoulders, 

 the tooth of which is somew^hat curved laterally as well as upwards ; 

 they are uniformly and minute coriaceous, without the usual lai'ge 

 punctures. The anterior tibias have three teeth, and the usual denticu- 

 lations on the carina beneath are enlarged into two broad conspicuous 

 teeth. The middle tibiae have two long and strong spines. The mcta- 

 thoracic episterna are very remarkably small and rounded. The 

 maxillary palpi are very slightly dilated (labials wanting).

The head is very different from that of ^. tinctilatum and splen- 

 didum ; the eyes being flat or even sunk, so that the form is ovate, 

 broadest before the eyes and gradually narrowed behind to the thorax ; 

 the space between the exterior teeth of the epistoma is narrow and 

 deeply concave ; the frontal furrows are narrow^ flexuous, scarcely 

 divergent, and do not reach the level of the hind margin of the eyes ; 

 the surface is glossy, smooth and black, with the sides of the neck 

 violet or blue. The thorax is rather smaller and narrower than the 

 head ; black, with broad brilliant green border. The elytra are of the 

 width of the thorax, and about as long as head and thorax taken to- 

 gether ; they have a small triangular emargiuation at the base of the 

 suture, and a broad concave depression down the middle ; there is no 

 trace of stria) or punctures ; the usual ocellated points on each side 

 of the base are one, or (sometimes) two, very large, and the marginal 

 punctures are also large and widely separated : the colour of the whole 

 disc is rich violet, with brilliant green basal, apical and lateral* borders, 

 but sometimes the green borders arc muclx wider. Tlie under-surface 

 and legs are shining black.
