NOTES ON THE ETHIOPIAN FRUIT-FLIES — II. 21 



Abdomen shining, with, no distinct dust and with very short black pubescence, the 

 ovipositor is very long, and when completely exserted measures 4 mm., in length. 

 Legs black, with yellowish coxae and tarsi, and the four anterior tibiae yellowish ; 

 front femora with 3 bristles beneath ; hind tibiae with a row of short black bristles. 

 The wings are as in semiangusta, but still broader and with the axillary cell broader ; 

 costal bristle long ; cross-veins less approximate, the hind one S-shaped ; lower 

 angle of the anal cell a little more produced. The pattern is also very similar, 

 but the marginal basal streak is complete, being equally broad from the base to 

 the stigma ; the two anterior indentations are of equal length, their tips passing 

 a, little beyond the 3rd longitudinal vein ; the two posterior indentations end at 

 the 5th vein and thus do not enter into the discoidal cell, which is entirely black ; 

 the first of these indentations has a slight greyish shade towards its middle. 



Type 9, a single specimen from N. W. Rhodesia, Chilanga, 23.vii.1913 

 {R. P. Wood). 



6. Aciura capensis, Rondani (1863). 



This species seems to be allied to the preceding ones and has likewise 4 scutellar 

 bristles ; but it is distinguished by the hyaline apical indentation, which is wanting 

 in all the other species. 



Described from the Cape and not foimd subsequently. 



7. Aciura ternaria, Loew, Berl. Ent. Zeits., v, 1861, p. 273, pi. ii, fig. 10. 



A very distinct species owing to its wing pattern, which is very different from 

 that of all the preceding species and is very near to that of Tephrella ; it may therefore 

 belong to this latter genus, but Loew says that the thorax is black. 



Originally described from Caffraria, and not recorded subsequently. 



8. Aciura binaria, Loew, Berl. Ent. Zeits., v, 1861, p. 274, pi. ii, fig. 11. 



A little species, smaller and shorter than the preceding ones, and very different 

 from all on account of its very peculiar wing pattern. 



Described from Caffraria ; there is a male specimen from Umbilo, Durban, 

 26. iv. 1914 (L. Bevis). 



The present species may perhaps be better placed in Spheniscomyia ; but it is 

 left here on account of its 2 scutellar bristles and its 3 lower or. bristles ; it needs 

 evidently the formation of a new genus, as is shown by its very peculiar wing pattern. 

 Costal bristle distinct ; hind cross- vein arched outwardly ; lower angle of the anal 

 cell acute but not produced. 



XXIII. Spheniscomyia, Bezzi (1913). 



I have redescribed the genus in my paper on the Indian fruit-flies ; but at present 

 it may be characterised by the peculiarly banded type of wing pattern, and by the 

 4 scutellar bristles, the apical pair being as stout or stouter than the basal one, 

 and being divergent instead of crossed ; the frons is shorter and has only 2 pairs 

 of lower or. ; the hind cross- vein is long, straight, and perpendicular. The genus is 

 thus restricted to two very widely spread species, of which only one is at present 

 recorded from Africa and is represented in the collection.
