tending at its upper surface to the hase of the antennae ; above the 

 base of the antennae is a longitudinal deep fovea, on cither side of 

 which (closely adjoining the margin of the eyes) is a more minute 

 longitudinal depression, which is most distinct at the immediate base 

 of the antennae ; the medial fovea is bounded on either side by a some- 

 what raised and glabrous surface, and terminates abruptly before it 

 reaches the base of the head ; the surface at the base is thickly and 

 very coarsely variolated ; colour flavo-fcrrugineous, the basal Hue 

 being distinctly fuscous ; the eyes are large and prominent. Thorax 

 broader than the head, transverse and contracted in front, anteriorly 

 very slightly emarginate ; the anterior angles depressed and mi- 

 nutely prominent ; the sides broadly marginatc ; at the base is a 

 transverse depression closely adjoining the basal line (more distinctly 

 apparent medially than at the sides), and corresponding in breadth 

 and depth to the lateral marginations ; the surface is finely and 

 thickly punctate throughout; flavo-ferrugincous. Scutellumtriangvlar, 

 rounded at the apex, impunctate, darkly flavo-fcrrugineous. Elytra 

 broader than the thorax, parallel, very slightly attenuated towards 

 the apex, which is rounded ; the surface is covered throughoixt with 

 exceedingly close and tolerably distinct punctures ; from the shoulders 

 to the apex are two almost obsolete and indistinct longitudinal ridges, 

 hardly perceptible except when under a high magnifying power ; the 

 colour throughout is of a bright metallic emerald-green, shaded me- 

 dially (in most specimens) with a tinge of copper colour. Antenna 

 robust and tolerably long, dilated towards the apex ; the first joint 

 broad, ovate, and very distinctly flattened ; the second short and 

 narrow; the third to the sixth elongated, and of equal breadth through- 

 out ; the seventh is sligh thj incurved, and extends apieally somewhat 

 beyond the insertion of the eighth ; the eighth is shorter, broadly 

 dilated, especially on the side of the apex of the seventh joint, and by 

 this lateral dilatation, as well as by its proceeding from the side 

 (rather than from the end) of the last joint, the seventh joint forms 

 a genicidation, or elbow, in the line of the antenna; ; the ninth and 

 tenth joints are broad and flattened, their outline being angulated at 

 the apex and slightly rounded off at the base ; the eleventh and 

 terminal joint is somewhat narrower than these, but equal in length 

 to both of them united : in form slightly innervated, the whole of the 

 joints of the antenna; appear to be flattened, rather than of a cylin- 

 drical form ; in colour the joints 1-5 arc flavous and 6-11 fuscous. 

 Legs tolerably robust, flavous throughout, — the apex of the posterior 

 femora being suffused with fuscous. 



The above description is taken from a male specimen. The females 

 have (as we might expect) filiform and simple antennoe, though of
