elongate, moderate, posteriorly dilated, costa gently arched, apex rounded- 
obtuse, termen obliquely rounded ; dark fuscous, strigulated with blackish, 
with very irregular thick dark violet-leaden-metallic transverse striae, 
towards dorsum somewhat strigulated with pale greyish- ochreous ; ter- 
minal area beyond a slightly outwards-curved line from § of costa to 
dorsum before tornus whitish-ochreous, marked with some blackish 
strigulae towards middle of disc and three small spots of dark fuscous 
irroration on costa ; cilia whitish-ochreous, with two more or less marked

Pretoria (Swierstra), Barberton (Janse) ; in December, two specimens. 
Cosmorrhyncha , n. g. 
Antennae in shortly ciliated. Palpi long, porrected, second joint 
triangularly smooth-scaled, terminal joint rather long, curved, pointed. 
Thorax without crest. Forewings with 3 from angle, 7 separate, to termen. 
Hindwings with basal pecten ; 3 and 4 connate, 5 closely approximated 
at base, 6 and 7 closely approximated towards base. 
Type ocellata Mabille. Forewings in without costal fold, hindwings- 
with thickened dorsal lobe. I formerly referred this species (under the 
name of acrocosma Meyr.) to Eccopsis Zell., which genus I have since merged 
in Argyroploce, but it is a curious type, and deserves generic separation 
on the ground of the peculiar palpi. It was originally described from 
Madagascar, which is probably its home. 
Argyroploce leucotreta, n. sp. 
5. 19-20 mm. Head dark grey on crown, face blackish surrounded 
with pale reddish-grey. Palpi porrected, dark fuscous, terminal joint 
rosy- whitish irrorated with dark fuscous. Thorax grey tinged with rosy 
and suffused with blackish irroration, apex of patagia pale, crest large.

fuscous spots separated by pairs of whitish strigulae ; a snow-white dot 
in disc at § ; ocellus small, edged with leaden-metallic lateral streaks 
touched internally with whitish and then partially finely edged with black, 
with two longitudinal black marks ; four small confluent dark fuscous 
black-edged spots forming an outwardly convex semicircle towards apex,

round this ; termen with several upwards- oblique whitish strigulae ; cilia 
dark leaden-fuscous. Hindwings with 3 and 4 short-stalked ; dark 
fuscous ; cilia grey, with dark fuscous subbasal line. 
Pretoria (Swierstra), in May, one specimen ; also one in my own 
collection from Durban, Natal, in October (Leigh).
