It is also probable that even specimens from Nyasaland, which have been labelled as diadematus (Bezz.), really belong to Text-fig. 166.—Side view and greater part of ventral view of hypopygium of $ Chasmoneura pectoralis (Lw.). The $$ of the varietal form, with black-haired pleurae in the $<$ and of the typical $£, all agree in having pale straw-coloured yellowish erect pubescence and fine hair-like depressed brassy yellowish scaling above, with black bristly hairs on ocellar tubercle, frons and antennae, with a tuft of silvery white scale-like hairs on each side of antennae, pale yellowish to straw-coloured yellowish hairs on face and a few black ones in front of silvery tuft on each side, in having slightly paler and more straw-coloured whitish hair on pleural regions and on sides of venter below, with the bristles on thorax and scutellum black, pubescence on abdomen with fairly dense adpressed brassy yellowish or golden scaling and with transverse rows of entirely black bristles above, venter with pale yellowish white transverse bristles; legs, as in $$, with the femora blackened to beyond middle, the hind ones with about 4-5 spines below from just before middle to apex and without any spines below on front and middle ones; interocular.
