30 Mr. A. J. T. Janse on new South African 



irrorated with black; all legs iiTorated witli black; branches of 

 antennae black ; fore- wing has basal half, except along inner margin, 

 irrorated with black, densely at cell and towards costa; a black 

 line on submedian fold till near vein 2, and in some specimens traces 

 of such a line in cell below upper median ; traces of a medial black 

 irrorated line; a black line on discocellulars, often interrupted at 

 middle; a postmedial rather broad Ime consisting of fuscous- black 

 irroration, angled at vem 8, somewhat incurved between veins 5 to 

 8 and inwardly oblique from vein 5 to inner margin, between every 

 vein from inner margui to vein 8 the line is curved inwardly, form- 

 ing a dentate edge on outer side; some fuscous-black irroration 

 before postmedial line along costa and some sprinkling below sub- 

 median fold; a moderate band of ground-colour following the post- 

 medial line and from there the terminal area is well irrorated with 

 fuscous- black; some black terminal lunules between the veins from 

 16-8 and a black suffusion from lb to postmedial line; cilia of 

 ground-colour, irrorated, except at base, with fuscous- black ; 

 hind- wing hyaline white and with the veins irrorated with light 

 buff ; some terminal fuscous irroration, especially on the veins, from 

 Irt to beyond apex; cilia light buff. 



Female : — whole wing, except at base, irrorated with fuscous. 

 Some specimens have on the fore- wing a brazil red (i) suffusion at 

 the postmedial and inner- marginal area, in the female type the 

 postmedial line consist mainly of a brazil red irroration sprinkled 

 with black. 



Underside: — fore- wing with the ground-colour as on upperside; 

 a fuscous suffusion and irroration in cell, along costa and beyond 

 postmedial line, which is indicated by a diffused irroration; ter- 

 minal lunules less distinct and fuscous- black ; a black suffusion on 

 the costa at basal third; hind- wing as on upperside, but fuscous 

 irroration above vein 8 to costa and terminal irroration narrower 

 and less distinct. 



Exp. Male type 33 mm. ; female type 34-5 mm. ; co-types 32- 

 33 ram. 



Hah. All but one specimen, eight in all, come from 

 Umkomaas in 18-29. i. 1914. 



This species is near to D. perstrigata Hmpsn. from 

 Swaziland, from which it differs in the pectination of the 

 antennae of the male becoming shorter at | and absent 

 on last |-, and also in the postmedial line being distinct. 



It must be placed in Hampson's Section II, B, but the 

 fore-wing has 4, 5 from a point in some specimens, in 

 others well apart.
