1886. Ent. Nachr., vol. 12, No. 4, pp. 51, 52. 



This fly was described from Pungo-Ndongo, Portuguese West Africa, 

 but is now known to be widely distributed over the southern half of 

 the African continent and the adjacent islands. The following material 

 is in the collection : 



$ 9 Bergroth's specimens (4, 5) from Stellenbosch, Cape Town, 1887 

 (Peringuey).

The position of Sc z is not as described by Karsch but is far removed 

 from the tip of Sc l9 the distance being about equal to the entire radial 

 sector. The wing has been well shown by Edwards in his Seychelles 

 report and is again figured in Plate X, fig. 3. This insect varies much 

 in the intensity of the wing-pattern, fully-coloured individuals having 

 C, Sc, and R light yellow with four large black marks along Sc, the 

 first at the wing base, the second the largest, the third at $c 2 , and the 

 fourth at the margin of the sector. Bergroth (Ann. Mag. Nat. Hist., 

 ser. 8, vol. 91, p. 580, 1913) denies that D. confinis, Bergroth (Wien.
