Black; the abdomen at the base dull metallic 

 green, the head with long black hairs, the thorax 

 thickly covered with fulvous hair, basal segment of 

 abdomen bearing longish fulvous hair, the rest with 

 long depressed silky hair, longest and thickest at 

 the apex and at the sides. Head closely punctured, 

 shining, metallic, centre of vertex raised into a pad- 

 like elevation, surrounded behind by a furrow ; the 

 lower ocellus is placed in a deep depression, and 

 from this a shallow furrow runs down to near the 

 apex of the pad-like elevation ; behind this the 

 vertex is depressed in the centre, through which 

 runs a furrow. Apex of clypeus broadly and 

 roundly incised ; labrum longer than it, shining, liot 

 metallic, impunctate, the apex rounded. Palpi hairy, 

 the four apical joints dirty yellow. Thorax closely 

 punctured ; on the mesonotum the puncturation is 

 nearly hid by the dense covering of hair; on the 

 pleurae the hair is longer, but not so thick, and 

 black in colour. Basal segment of abdomen finely 

 punctured, and with a longitudinal keel down the 

 centre. Legs densely pilose, coxae and femora 

 punctured, black; four hind tibiae and tarsi white, 

 except on the inner side of the ai^ices of the tibiae ; 

 fore tarsi obscure fuscous ; claws bifid. Wings 

 yellowish-hyaline ; a small brownish spot at base 

 of cubital cellule ; stigma yellowish, black at base ; 

 costa yellowish, except before stigma; transverse 

 radial nervure received before the middle of the 

 second cubital cellule, which is about one-fourth 

 longer than broad, and gradually becomes wider 

 towards the apex. Antennae 7-jointed, the seventh 

 joint longer and thicker than the sixth.
