NOTES ON THE ETHIOPIAN FRUIT-FLIES — I. 217 



11(48). Third longitudinal vein bristly throughout its whole length, or at least from 

 the base to the small cross- vein ; ocp. mostly black ; arista very often 

 pilose or plumose ; scp. well developed ; lower angle of the anal cell 

 mostly drawn out in a point which is longer than the second basal cell. 



12(29). Dc. placed only a little behind the connecting line between the a. sa., and 

 thus not very far from the suture. 



13(16). Three strong i. or. present ; hind cross- vein placed obliquely outwards, that 

 is, with its upper end more distant from the base of wing than the 

 inferior one ; upper angle of discoidal cell therefore acute ; occiput with 

 lateral swellings below ; eyes narrow. 



14(15). Body prevalently black, with striking yellow or white markings ; wings 

 with the discoidal cell short and broad, adorned with blackish longi- 

 tudinal bands and with a A-shaped band near the hind border 



Carpophthoromyia, Aust., p. 224. 



15(14). Body prevalently yellowish ; wings with the discoidal cell more elongate 

 and only with some yellowish, partly infuscated, transverse bands 



Leucotaeniella, gen. nov., p. 227. 



16(13). Only two i. or. present ; hind cross- vein inwardly oblique, its lower end being 

 more remote from the wing base than the upper one ; the acute angle of 

 the discoidal cell is therefore the lower one. 



17(28). Middle scp. well developed ; legs short and stout ; wings of broader shape ; 

 head not " balanced " (see p. 241), with rather rounded eyes and less 

 developed lower occipital swellings. 



18(19). Third antenna! joint distinctly pointed at the upper end ; arista long 

 plumose ; lower occipital swellings rather developed 



Chelyophora, Rond., p. 229. 

 19(18). Third antennal joint rounded at end. 

 20(27). Basal segment of the costa destitute of bristles before the costal bristle. 



51(26). Head, in side view, less shortened, the eyes being therefore more rounded ; 



thorax and scutellum prevalently yellowish or reddish, with black spots ; 



wings with yellowish bands and blackish basal streaks, the band passing 



over the hind cross-vein not united with the basal one. 

 22(23). Arista with short pubescence, more distinct on the upper side ; frons of the 



male with conspicuous spatulate appendages 



Ceratitis, MacLeay (s. str.), p. 230. 

 23(22). Arista with longer pubescence on both sides or shortly plumose ; frons of 



the male without such appendages. 

 24(25). Middle legs of male broadly feathered, at least on the tibiae 



Pterandrus, gen. nov., p. 231. 

 55(24). Middle legs of male simple . . . . . . Pardalaspis, gen. nov., p. 233. 



26(21). Head distinctly shortened in side view, the eyes being more narrow ; 



thorax and scutellum shining black, sometimes with white markings ; 



wings with blackish bands radiating from the base, which is destitute of 



streaks ; arista long plumose . . . . Trirhithrum, gen. nov., p. 236.
