and tornus, sometimes obsolescent: cilia grey, becoming dark fuscous round 
costa and apex. Hindwings and cilia grey. 
Rhodesia, Salisbury, Umtali, in December and January (Janse); two 
specimens. 
Ascalenia conformata n.sp. 
^ 8 mm. Head light greyish-ochreous speckled with blackish. Palpi dark 
fuscous, slightly pale-speckled, apex of second joint ochreous-whitish. An- 
tennae dark grey, apical third white. Thorax greyish-ochreous. Abdomen grey, 
anal tuft dark fuscous. Forewings lanceolate; whitish-grey-ochreous irrorated 
with dark fuscous, towards costa irrorated with blackish, a transverse line of 
blackish irroration near base; stigmata large, dark fuscous, plical rather ob- 
liquety before first discal ; a whitish-ochreous spot on costa at f , and indistinct 
dot on tornus opposite : cilia, grey, on costa and round apex suffused with dark 
fuscous towards base. Hindwings grey; cilia light grey. 
Natal, Durban, in November (Janse): one specimen. Near isotacta from 
the Seychelles. 
Ascalenia nudicornis Meyr. 
The antennae in this species have the apical fourth ochreous-whitish, and 
the forewings should have been described as wholly dark bronzy-fuscous, 
without perceptible stigmata; I am of opinion that the specimens with visible 
stigmata should be referred to pulverata, but these species require further study. 
They are probably attached to Tamarix, and might be easily bred. 
Tr achy dor a scandalous n.sp. 
9 II-I2 mm. Head white sprinkled with grey. Palpi white, second joint 
with two rings of dark grey irroration, terminal joint with four blackish rings. 
Thorax whitish irrorated with dark fuscous. Abdomen light grey, three basal seg- 
ments suffused with light ochreous-yellowish. Forewings elongate-lanceolate; 
3 absent ; ochreous-brown ; an irregular streak of dark grey suffusion irrorated 
with whitish from ^ of costa to termen beneath apex, where it forms a triangular 
more whitish blotch marked with a black longitudinal line, another streak 
from base of costa to tornus, and blotches on dorsum before and beyond 
middle, these sometimes all largely confluent so as to obscure nearly the whole 
wing; transverse whitish ridgetufts finely edged with black, viz. three repre- 
senting stigmata, plical obliquely before first discal, two above dorsum before 
and beyond middle, one from costa at f , and one resting on tornus; a whitish 
line along costa towards apex: cilia light grey, suffused with white beneath 
apex and at base along termen, on costa white with blackish basal line and 
dark grey apical shade. Hindwings with 3 and 4 closely approximated at base; 
grey; cilia light grey. 
Transvaal, Pretoria, in January and February (Swierstra) ; three speci- 
mens. A d from Magude, Portuguese East Africa, in November (Swierstra), 
though not in very good condition, is probably the other sex of this species; 
it has a very long expansible pencil of ochreous-whitish hairs from base of 
hindwings lying beneath forewings. 
Mompha cyclocosma n.sp. 
$ 15-17 mm. Head whitish-grey, face white. Palpi whitish irregularly 
irrorated with dark fuscous, terminal joint loosely haired posteriorly towards 
middle. Thorax grey mixed with dark fuscous and whitish. Abdomen whitish-
