26 Mr, A. J. T. Janse on new South African 



black. Hind- wing irrorated with ferruginous, very densely at 

 terminal half; postmedial line distinct and from costa to vein 1&, 

 then interrupted and continued between 16 and la; a similar 

 streak towards base on Ic ; some fuscous- black irroration at apical- 

 terminal area ; terminal line more broad and distinct than in male ; 

 cilia ferruginous, with fuscous scale at end of veins from 8 to Ic. 



Underside as in M. confusa, but more suffused and irrorated with 

 ferruginous, especially in female. 



Exp. Male and female types 26 mm. ; male co-type 22 mm. 



Hab. Umtali, male type, 5. i. 1918; female type, 

 9. i. 1918; male co-type (in British Musemii), 12. i. 1918. 



In ground-colour and general marking this species is 

 almost identical to M. confusa mihi, but the additional 

 irroration of ferruginous (xiv), especially on the hind- 

 wings, give this species a darker and more coppery 

 appearance. 



Macalla confusa, sp. n. 



Male. Paljii, antennal process, thorax, base and ajiical part of 

 fore-Aving deep olive (xl) ; ground-colour of fore- wing and hind-wing 

 on upper- and under- side, thorax on underside, legs and abdomen 

 cartridge-buff (xxx); head, palpi, antermal process and thorax 

 irrorated with black scales; antennal process thickly covered with 

 rather long scales and hairs, especially towards apical half, process 

 reaching to end of thorax ; antennae ciliated, shaft fuscous ; palpi 

 reaching above vertex of head, smoothly scaled, irrorated with 

 black scales, very densely at third joint, and half of second joint; 

 thorax and abdomen on underside irrorated with black; femora 

 of all legs densely irrorated with black ; tibia of all legs with a ring 

 of ground-colour in middle and densely irrorated with fuscous-black 

 (xlvi); tarsi of all legs fuscous-black ringed with ground-colour; 

 abdomen with first and second segment each with a triangular black 

 dense irroration so arranged that the ajiices touch each other; 

 third and fourth segment irrorated with black on posterior two- 

 thirds, so as to leave an anterior ring of ground-colour; remaining 

 segments rather densely irrorated with black, especially posteriorly. 

 Fore-wing with basal deep olive patch sparsely irrorated with black ; 

 base at inner margin showing some ground-colour; a tuft of pro- 

 jecting scales on outer half of deep olive patch at inner margin ; 

 three black fans of spreading scales, one beloAV lower median on 

 subbasal line, which is only indicated at costa by a faint striga of 

 ground-colour, second half-way in cell, third and largest at end of 

 cell and projecting beyond the medial line which forms the boundary 

 of the apical deep olive patch ; medial line almost straight, slightly
