The bead is black, slightly tinged with purple, almost impunc- 

 tate, with a small longitudinal impressed line in the middle of the 

 crown ; the face bears two oval spots between the antennae, two 

 other similar spots behind the lower part of the eyes, and an 

 interrupted fulvous line across the lower part of the face ; the lip 

 and mandibles are black, the antennse are velvety and black 

 (except the polished basal joint), the third and fourth joints 

 being marked with a large patch of white pile ; the prothorax is 

 black, with a purple gloss, smooth and almost impunctate, with a 

 small round spot near each anterior angle, and a larger transverse 

 one near the hind angles, which latter are produced into a small 

 lobe extending backwards, and received into an emargination near 

 the shoulders of the elytra. The elytra are golden-green, under 

 a lens very delicately chagreened and punctate ; near the shoulders 

 they are elevated, and clothed with black velvet-like pile ; there 

 is also another transverse patch of the same clothing beyond the 

 middle, the disc beneath the pile being of a bluer tint ; at the base 

 the elytra are marked with six fulvous spots, the four middle 

 ones being pointed behind ; beyond these is an interrupted fascia 

 of small paler fulvous spots, followed by a slender whitish line 

 running parallel with the suture, and with its extremity incurved 

 towards the disc of each elytron, and almost continuous with a 

 transverse fulvous band extending inwards from the lateral mar- 

 gin ; beyond these is a large fulvous y-like mark, the lower
