tures and clothed with stiff fuscous bristles ; the hypopygium seems to be a 

 trifle longer. Venter dark brown with a very thin and short white tomentum. 



Wings. See above ; the veins very dark brown, almost black ; nerv. rec. 

 I just in the middle of second cubital cell, nerv. rec. 2 a trifle behind middle 

 of third cub. c. ; second cub. c. very narrow above. 



Legs ferruginous, only the claws and the spurs of second and third pair 

 blackish. Spur of middle tibiae microscopically pectinate ; pulvilli at least half 

 the length of claws. 



Long. tot. lo-ii mm., lat. abd. 3.3 mm. 



Male. — Exactly like the female, only the scutellum is not so strongly 

 bituberculate, the depression between the tubercles is not black and the ab- 

 domen is very elongate, aft'ecting the shape of Osiris; it is at least three times 

 longer than the mesonotum and more than twice as long as broad. The 

 pygidial plate is longer than broad, rounded at apex and with sharp lateral 

 edges. 



Long. tot. II mm.; lat. abd. 2.9 mm. 



Paraguay, Puerto Bertoni, April 22, 1909, on flowers of Vernonia 

 sp. (Compositse). 



In Dr. Friese' tables of the Argentine species (Flora og Fauna, 

 Silkeborg, 1908) this species runs to nobilis (J) or {unifasciatus =) 

 variolosns Holmlg. (J*) ; it is however quite distinct from either. 

 J 2. Cyphomelissa garleppi, new species. 



Black, entirely covered with bluish green pubescence, longest on the 

 mesopleurae (there with a blue tinge), legs and abdomen. Wings almost 

 hyaline with darker exterior margin and with a strong metallic blue tinge 

 all over. 



Female. — Head much narrower than thorax. Eyes reaching base of 

 mandibles, not converging below. Mandibles rather densely covered with 

 elongate punctures, except the blunt tips. Labrum distinctly punctured. 

 On the rest of the head or body no sculpture can be seen on account of the 

 extremely dense pubescence. Clypeus with its anterior margin very faintly 

 emarginate. Antennre with a stout scape, bluish green by pubescence ; the 

 rest black and nude ; the pedicel very short, its length scarcely one-fourth of 

 the first joint of the flagellum, this a little longer than any of the succeed- 

 ing joints. Posterior ocelli much nearer to each other than to the eyes or 

 margin of the vertex. 



Thorax stout with long bluish green hair. Tegulae naked, minutely punc- 

 tured. 



Abdomen much longer than head + thorax, covered with shorter glitter- 

 ing green pubescence and longer blue hairs ; the pygidial plate partly hidden 

 under the pubescence, the visible part opaque, its apex rounded. Venter not 

 •quite as densely pubescent as dorsal surface. 



Wings. Median cell much shorter than submedian ; second cubital cell 

 the largest, rhomboidal, with nerv. rec. i interstitial with second transverse 

 cubital vein ; third cubital cell triangular, its outer margin strongly curved.
