NOTES ON THE ETHIOPIAN FRUIT-FLIES — I. 221 



83(82). Head not depressed and proboscis usually short and simple ; if the proboscis 

 is geniculate, its terminal part is shorter than the basal one. 



84(89). Wings with a properly reticulate pattern, extended over all, or almost all. 



their surface. 

 85(88). Frons flat, and not at all or little produced above ; ovipositor flat. 



86(87). Frons of usual breadth ; antennae rather approximate ; wings not at all 

 widened, with the stigma unicolorous or with a single hyaline spot 



Euribia, Meig. 



87(86). Frons very broad ; antennae broadly separated ; wings distinctly widened, 

 usually with short, radiating, marginal streaks and with a bimaculate 

 stigma . . . . . . . . . . . . Campiglossa, Rond. 



88(85). Frons convex and prominent above; ovipositor conical 



Camammyia, Hend. 



89(84). Wing pattern not extended over the greater part of surface, but either the 

 hind or the basal half is quite hyaline. 



90(91). Wings dimidiate, that is, on the fore half with a dark reticulation, at least 

 at the end, on the hind half either quite hyaline or with a very faint 

 reticulation.. .. .. .. .. .. Acanthiophilus, Beck. 



91(90). Wings with a star-shaped pattern on the terminal half Trypanea, Schrank. 



92(7). Wings with the costa broadly interrupted at end of the auxiliary vein, and 

 there with a projecting border ; they are provided with strikingly 

 distinct " bullae " ; ocp. thick and yellowish ; arista bare or shortly 

 pubescent ; dc. near the suture ;. 3rd longitudinal vein bare, small cross- 

 vein often obliterated ; anal cell obtuse or acute below, but not prolonged 

 (subfam. Schistopterinae). 



93(94). Second longitudinal vein long, ending at costa nearer to the end of the third ; 

 anal cell acute below; 3rd and 4th longitudinal veins not or but little 

 diverging distally . . . . . . . . . . Rhabdochacla, de Meij. 



94(93). Second longitudinal vein short, ending at costa nearer to the first ; anal 

 cell obtuse below ; 3rd and 4th longitudinal veins exceedingly divergent 

 outwardly. 



95(96). Scutellum with 6 bristles ; 3rd longitudinal vein ending before the apex of 

 wing. . . . . . . . . . . . . . Rhochmopterum, Speis. 



96(95). Scutellum with 4 bristles ; 3rd longitudinal vein ending at apex 



Schistopterum, Beck. 

 I. Subfam. DACINAE. 



The Ethiopian species of this subfamily have been dealt out by me in two previous 

 papers, published in this Bulletin.* 



Of the Oriental genus Meracantliomyia there is a species, antennata, Hendel 

 (Wien. ent. Zeit., xxxi, 1912, p. 11), described from W. Africa, Ashanti.
