four apical joints tapering 1 , distinctly longer than broad. Thorax and 

 median segment finely and closely punctured ; abdomen finely 

 shagreened ; first tergite scarcely longer than its apical breadth ; 

 second tergite almost as long as the first, as broad at the apex as 

 long ; seventh tergite small, coarsely punctured ; hypopygium rounded 

 at the apex. Second abscissa of the radius shorter than the 

 first, less than one-third the length of the third ; first transverse 

 cubital nervure strongly oblique, sharply elbowed near the cubitus ; 

 second and third transverse cubital iiervures straight, almost at right 

 angles with the cubitus. First recurrent nervure received just before 

 two-thirds from the base of the second cubital cell, second a little 

 beyond one-third from the base of the third cubital cell. Hind tibiae 

 distinctly serrate. 



Hal. M'fongosi, Zululand ( W. E. Junes), May, 1917. 



Very near A. rufocaudata Turn., but differs in the much stouter 

 antennae, in the greater proportionate length of the basal tergites 

 compared with their breadth, and in the much greater extent of the 

 yellow colour on the legs.

9 . Nigra ; flagello aurantiaco, articulis tribus apicalibus infus- 

 catis ; scapo, tarsis articulo basali, femoribus apice extreme, tibiisque 

 ferrugineis, maudibulis basi, f route clypeoque fusco-ferrugineis ; alis 

 fusco-violaceis, venis nigris. 



Long. 15 mm. 



9 Clypeus almost transverse at the apex, the angles broadly 

 rounded. Antennae tapering to the apex, the second joint of the 

 flagellum much longer than the third ; eyes separated on the vertex 

 by a distance distinctly less than the length of the second joint of the 

 flagellum ; the posterior pair rather nearer to the eyes than to each 

 other. Scutellum rather strongly convex ; median segment opaque, 

 with a. very distinct, but shallow, longitudinal groove in the middle. 

 Comb of the fore tarsi well developed, with three spines on the basal 

 joiut ; inner spine of hind calcaria more than half as long as the hind 

 metatarsus ; ungues of the fore tarsi bifid, of the others uuideutate. 

 Third abscissa of the radius a little more than half as long as the 

 second, a little shorter than the second transverse cubital nervure ; 

 second recurrent nervure received beyond two-thirds from the base of
