Cerotalis amabilis, n.sp. 



Upper surface of a bronzy-olive colour, the sides and base of 

 the prothoi'ax and the sides of the elytra narrowly margined with 

 green ; imder surface shining black with a slight metallic tinge, a 

 bright blue patch on each side of the head behind the buccal fissure ; 

 legs black ; parts of the mouth and antennae almost black. Head 

 not large ; mandibles rather long ; clypeus wrinkled, with a 

 setigerous puncture on each side, behind which the shallow 

 frontal impressions extend, these also wi'inkled ; forehead raised 

 above the plane of the vertex, and squai-ely divided from the 

 occiput ; occipital part smooth ; eyes not very prominent, the 

 head not swollen behind them. Antenn£e rather short, sub- 

 moniliform, four first joints glabrous, the others thickly covered 

 with short hairs. Prothorax a little longer than broad 

 (4| X 4^ mm.), convex, declivous behind, the basal part well 

 defined by the posterior transverse line ; the sides very lightly 

 rounded to the anterior angles, behind them almost parallel to the 

 middle, then narrowed to the base ; marginal border not wider 

 or at all produced at the anterior angles, entire on the base, 

 sharply sinuate on each side a little in front of the basal angles, 

 then straight ; the basal angles right angles. Elytra oval 

 (8^x5 mm.), convex, covered with rows of closely -placed fine 

 punctures, forming light interrupted striae, and with minute 

 transverse scratches ; rugulose towards the apex ; sides sub- 

 parallel ; the shoulders lightly rounded, not narrowed ; base 

 declivous and lightly emarginate behind the scutellum ; apex 

 broadly rounded and somewhat flattened towards the margins ; 

 suture strongly im{)ressed ; the lateral margins becoming thicker 

 and.more reflexed towards the apex ; a part along the sides rather 

 rough and not polished like the rest of the elytra ; three posterior 

 marginal impressions almost as usual in Promecoderus, only the 

 middle one not so elongate. The ventral segments smooth, the
