124 Annul* <>f the South Africa ii Museum. 



River (Cape), January 10th, 1887, labelled by Bigot as Anthrax pusilla, 

 Wied. An additional example from Kimberley (Cape), 1918 (J. H. 

 Power) . 



ANTHKAX HEMIMELAS, Speiser (1910). 



A black species of small size, very distinct on account of its perfectly 

 dimidiate wings. 



Described at the same time by Speiser from Kilimaudjaro and by 

 me as A. hontugeneus from Nyassa, it is interesting to record it from 

 South Africa. A single female from M'Fongosi, Zululand, December, 

 1911 (W.E.Jones). 



ANTHKAX FUSCIPENNIS, Ricardo (1903). 



Distinct owing to the reduced black pattern of the wings, which 

 have a tooth-like projection on the fore border, the apical half of anal 

 and axillarv cell being hvaline. 



/ o * 



A single female specimen from Bushmanland, Henkries (Cape), 

 October, 1911 (R. M. Lightfoot). 



This species seems to be widely spread over all the Ethiopian region, 

 but was not recorded from South Africa. It seems that muscarius, 

 King (nee Pallas), from ~E>.rypt,fuiicipennis,T&\c., from Sokotra, detitatus, 

 Beek, from Egypt and camptodadius, Bezzi, from Nyassa are all the 

 same species, the latter one representing a colour variety with entirely 

 black first basal cell, and therefore without a tooth-like projection on 

 the fore border. 



SPONGOSTYLUM, Maccmart (1840;. 



Under this name I include the species which Becker has placed in 

 his restricted genus Argynamoeba ; they are distinguished from the 

 preceding genus chiefly in the shape of antennae and in the wing- 

 pattern. All the following species have only 2 submarginal cells and 

 they may be distinguished as follows : 



1 (2). Origin of the second longitudinal vein placed a little before the 



discal cross-vein ; base of the second vein and of the upper branch of 

 the cubital fork destitute of stumps, or if present they are very 

 short ... . mulicum, sp. nov. 



2 (1). Origin of second vein just opposite to the discal cross-vein ; base of 



second vein and of upper branch always provided with long stumps. 



3 (4). No brown spot at the base of the cubital fork or a very indistinct 



one, abdomen with narrow or less distinct yellow hind border on 

 segments, and on sides, with usually tufts of black hairs, or with very 

 few scales . . inciswale, IMac<|.
