. Annals of the South African Museum = Annale van die Suid-Afrikaanse Museum. Natural history. 43° ANNALS OF THE SOUTH AFRICAN MUSEUM greyish to brassy, and that on pleurae much darker, more blackish brown; fine scaling on abdomen shorter, duller, more greyish yellowish or duller ochreous yellowish; scaling on venter finer, dark or mostly blackish, gleaming brownish, not pale and whitish as in hessii. Wings with the infuscation darker, blackish brown to dark chocolate, more uniform, not paler in middle of cells; clear gap in front of middle cross vein area narrower and the spot on latter tending to be connected with basal infuscation, without cloudiness in first submarginal and first posterior cells beyond cross vein. Antennae with the terminal joint of joint 3. Text-fig. 153. Side view of hypopygium, dorsal view of right beaked apical joint, ventral view of apical part of aedeagal structure, and side view of left terminal lamella of <$ Anthrax bifarius n. sp. relatively shorter. Hypopygium of $ (text-fig. 153) differs in having very short, obliquely truncated apical prongs, entirely different type of beaked apical joints; aedeagal complex has no wattle-like process apically below. Last sternite is very much shorter than in any of the species dealt with, and dorso- apical angles of terminal lamellae not very sharply hook-like. From bijlexus it may be distinguished by its less extensive basal infuscation in wings, the infuscation extending only to about middle and not beyond middle of anal and axillary cells; clear gap before discal spot deeper, more distinct even in $, the latter spot thus not appearing as a dentate process; in having three distinct spots on cross veins; in having paler hair-like scaling above; less extensive silvery scaling at end of body; and by its different type of hypopygium. From 5 0*0* and 3 $$ (types in the South African Museum and paratypes in the British and Transvaal Museums). Length of body: about 9-13 mm. Length of wing: about 10-14
