NOTES ON THE ETHIOPIAN FRUIT-FLIES — II. 41 



XXXIV. Acanthiophilus, Becker (1908). 

 I here adopt this name for the species which have dimidiate (but always reticulate) 

 wings, thus recalling the condition found in Ocneros (Hemilea), with which the present 

 genus was originally believed to be related by its author. 



1. Acanthiophilus helianthe, Rossi (1790). 



Recorded by me in 1908 from Erythraea, Adi Caie ; and I have now a specimen 

 before me, certainly belonging to this widely spread South European and Mediter- 

 Tanean species. 



2. Acanthiophilus ochraceus, Loew, Berl. Ent. Zeits., v, 1861, p. 295, pi. ii, fig. 25. 

 I refer with doubt to the present genus this species, which has a faint wing pattern, 



like that of lauta, but has several darker spots on the anterior half. 

 Described from Caffraria and not recorded subsequently. 



XXV. Teypanea, Schrank (1795). 

 Even this genus is very doubtful in its limits, being absolutely an artificial one, 

 but the species can easily be recognised on account of the star-shaped apical pattern 

 of the wings, and seem to form a natural group, because they are well represented 

 in all the zoological regions. Most of the Ethiopian species have a bicubitate 

 proboscis, and usually only 2 bristles on the scutellum ; I can distinguish the 

 following, some of which are probably only varieties, and are in part closely allied 

 ■to European or Mediterranean forms. 

 1(8). Stigma black, and broadly united with the apical black spot ; the single 

 basal hyaline spot of the first posterior cell is smaller than the distance 

 between the 3rd and 4th longitudinal veins. 

 ■2(7). Second longitudinal vein long, its distance from the end of the first being 

 longer than that from the end of the second ; in the black apical spot 

 there is a deep black dot on the 3rd vein before its end. 

 ■3(6). Sixth longitudinal vein long ; the discoidal cell crossed by a single fuscous 



ray near its end. 

 4(5). Scutellum with only 2 bristles ; the black apical spot sends 3 rays to the 

 hind border of the wing ; no black spot on middle of the 5th vein ; lower 

 angle of the anal cell acute . . . . . . . . augur, Erauenf. 



5(4). Scutellum with 4 bristles ; 4 rays reaching the hind border ; a black spot 

 on the 5th vein, lower angle of the anal cell a right angle, not prolonged 



auguralis, Bezzi. 



6(3). Sixth vein short ; the discoidal cell crossed by 2 fuscous rays, one in the 



middle and another at end ; scutellum with 4 bristles hexapoda, sp. n. 



7(2). Second longitudinal vein short, its end being nearer to the end of the first ; 



the apical spot is more blackened near the end, but has no distinct deep 



black spot on the 3rd vein ; scutellum with 2 bristles confluens, Wied. 



■8(1). Stigma colourless or yellowish, not united with the apical black spot, or 



only with a narrow, incomplete and slightly coloured streak ; scutellum 



with 2 bristles ; basal hyaline spot of the first posterior cell extending 



from the 3rd to the 4th vein.
