 a color variety of anxius, but since nothing is known of its habits, 

 it is best to retain it for the present, at least, as a valid species.

Male. — Form similar to that of anxius, slightly flattened above, and 

 feebly shining; head bronzy green in front, becoming brownish cupre- 

 ous on the occiput ; pronotum dark brown, with a more or less cupreous 

 tinge; elytra olivaceous black; beneath aeneous, with a feeble cupre- 

 ous reflection, and more shining than above. 



Head with the front rather narrow, nearly flat, about equal in 

 width at top and bottom, the lateral margins broadly, arcuately 

 expanded near vertex, and with a narrow, longitudinal groove extend- 

 ing from the occiput to middle of front; surface rather coarsely, 

 irregularly rugose, densely, coarsely punctate, and sparsely clothed 

 with short, semierect, white hairs on lower half, and a distinct, round, 

 smooth elevation on each side behind the antennal fovea; epistoma 

 transverse between the antennae, and the anterior margin elevated, 

 and broadly, rather deeply, arcuately emarginate; antennae extend- 

 ing to about middle of pronotum, serrate from the fourt joint, 

 and the outer joints about as long as wide; eyes large, strongly 

 elongate, and almost equally rounded beneath and above. 



Pronotum one-half wider than long, base and apex equal in width, 

 and widest at middle ; sides regularly, arcuately rounded from apical 

 angles to near base, where they are feebly sinuate; when viewed from 

 the side the marginal carina is strongly sinuate, the submarginal 

 carina feebly sinuate, the two carinae widely separated anteriorly, 

 and connected to each other near the base; anterior margin feebly 

 sinuate, and the median lobe feebly, broadly rounded; base feebly, 

 broadly emarginate at middle of each elytron, the median lobe 

 broadly rounded, and subtruncate in front of scutellum ; disk moder- 

 ately convex, with a broad, shallow depression in front of scutellum, 

 a round, rather deep depression on each side of middle, a broad, 

 oblique, depression on each side along lateral margin extending to 

 base, and with sharply defined, arcuate, prehumeral carinae ; surface 

 finely, densely, transversely rugose, finely, densely punctate between 

 the rugae, and sparsely clothed with very short, inconspicuous hairs. 

 Scutellum strongly, transversely carinate, and the surface finely, 

 densely reticulate.
