Antennae elongated, considerably longer than the head, third joint long, lanceolate, with an attenuated and pointed apex which is turned a little upwards; the joint is distinctly hairy; the antennae are black, yellow beneath the basal joint. Thorax green or golden green, gener- ally with a more golden middle stripe; sometimes the thorax is more aeneous; it is distinctly greyish pruinose, somewhat shining; scutellum very finely yellow pubescent; postscutellum green, grey pruinose. Pleura greenish or aeneous, greyish pruinose; propleura with few, short, pale hairs above, and a black prothoracic bristle. Abdomen green with golden, sometimes more coppery reflexes; it is distinctly white pruinose downwards, and has very narrow, darkened hind mar- gins to the segments, or these are almost wanting; it is clothed with short, black hairs, at the sides with some pale hairs intermingled, and it has hindmarginal bristles, which are a little long on the first segment, and also increase in length towards the end. Venter greenish grey, very slightly pale-haired. Hypopygium black or slightly aeneous, greyish pruinose; eighth segment with black hairs; there are long, straight, almost styliform posterior ventral lobes, ending with a pair of small spines, they issue a little more forwards than commonly; there are also a little projecting middle ventral lobes, but this part of the hypopygium is a little unsymmetrical; the inner lamellae issue more ventrally than commonly, they are long, the median curved a little downwards, hook-shaped at the apex; the lateral are straight, a little dilated, and at the apex with a dilatation which is separated off by an excision; the outer lamellae somewhat small, almost rectangular, white, with a blackish margin only at the apex; at the end there are two longer and a few shorter teeth with curved, black hairs; dorsally to the teeth there are
