 Lorentz River, September. 



Black, the underside of the antennal scape and the basai 2 joints of the flagellum 

 rufo-testaceous, a triangular mark on either side near the middle of the clypeus, a line oppo- 

 site the antennae at the eyes, a mark on the base of the mandibles, a curved mark on the 

 sides of post-scutellum, a line on the sides of the i st abdominal segment above and one ail 

 round the apex of the 2 nd , pale yellow; wings almost hyaline, the apex fuscous violaceous. Q* 



Length 1 1 mm. (total). 



Clypeus a little longer than it is wide, gradually narrowed from the eyes to a point 

 at the apex; somewhat strongly but not closely punctured. Base of thorax transverse, the 

 apex with the sides broadly roundly dilated. Apex of post-scutellum with a steep slope, 

 transverse. The lower part of the propleurae has 3 or 4 stout longitudinal striae. 2 nd abdo- 

 minal segment roundly narrowed at the base, where it is distinctly wider than the ist ; it is 

 longer than it is wide at the apex; its puncturation is weak, much weaker than it is on the 

 thorax and head. The lower half of the metapleurae is very sparsely punctured, the upper 

 more sparsely and irregularly than the mesopleurae.

Dark metallic green, the space between the top of the eyes, across the ocelli, the 

 pronotum and the mesothorax violaceous purple, the i st abdominal segment (especially at the 

 apex) with metallic violaceous tints; the antennae black, the scape dark green; legs green, 

 covered with a white pile; the tarsi black; wings fuscous violaceous, darker along the fore 

 margin ; the i st abscissa of radius a little longer than the following 2 united ; the 2 nd - one 

 fourth of the length of the 3 rd ; the ist récurrent nervure received near the apex of the basai 

 third, the 2 nd near the apex, close to the 2 n<i transverse cubital nervure; the radial nervure is 

 almost appendiculated. Head and thorax densely covered with a short pale pile; closely, 

 strongly punctured, the clypeus as strongly, but so closely as the front; the scutellum 

 less strongly, not to closely as the post-scutellum, which becomes narrowed gradually 

 from the sides to the centre, which is rounded. Seen from above the metathorax is formed 

 of 2 broad rounded lobes, the centre narrowed almost to the post-scutellum. Metapleurae 

 closely punctured above, the lower part weakly, sparsely punctured to the furrow, where 

 there is an almost smooth space. On the mesopleurae a moderately wide, crenulated furrow 

 runs down from the tegulae ; from its apex a narrower, weakly crenulated one runs 

 obliquely to the base of the pleurae. The narrowed basai part of the i st abdominal segment 

 is smooth and is a little longer than wide; the dilated apex is bell-shaped, as long as it
