I Amhlyxena pilifera n.sp. 
! ^26 mm. Head glossy whitish, with a few dark grey specks. Palpi whitish 
i sprinkled with dark fuscous, second joint long, terminal joint less than of 
I second, obtuse. Thorax ochreous-whitish tinged with fuscous anteriorly, with 
three dark fuscous longitudinal lines. Abdomen ochreous-whitish sprinkled 
with fuscous. Forewings narrowly elongate-lanceolate; fuscous suffusedly 
irrorated with whitish ; costal edge blackish towards base ; a blackish subcostal 
streak from base to beyond middle, three between veins towards costa pos- 
teriorly, one in disc from to f , one beneath anterior portion of this, and one 
along fold from base to near middle of wing; a marginal series of black elongate 
marks on posterior part of costa and termen: cilia whitish-grey. Hindwings 
dark grey; cilia pale whitish-grey-ochreous. 
Transvaal, Woodbush Village, in April (Swierstra) ; two specimens. 
Perhaps the genus Amhlyxena should be merged in Iriothyrsa, to which it is 
very similar in essential characters, the differences of the peculiar palpi being 
regarded as specific. 
GRACILARIADAE 
Lithocolletis triarcha Meyr. 
Transvaal, Pretoria, in January and March (Swierstra); two specimens. 
Hitherto only recorded from India; the larva mines leaves of cotton {Gossy- 
pium ) . 
Acrocercops conflua Meyr. 
The confused, variable, and irregular markings of this species (of which 
I have now seen a series) are not well expressed in my description, drawn from 
a single specimen. There are generally suffused black longitudinal streaks in 
disc above and below middle, sometimes merged in a more general blackish 
suffusion; the whitish markings do not form any defined striation, but rather 
several slender irregular more or less oblique streaks or marks beneath or from 
costa, and the dorsal streak should rather have been described as several very 
oblique irregular white streaks or marks, especially two at | and middle of 
dorsum, edged with black, with slight whitish suffusion between them, some- 
times connected to form an irregular streak; the oblique streak from tornus 
is properly single, with sometimes some parallel whitish suffusion beyond it; 
the oblique transverse praeapical streak is often interrupted in middle. In the 
c? there is a median streak of dark fuscous suffusion on lower surface of fore- 
wings, and some long fine expansible hairs from costa of hindwings near base, 
which lie on this streak when at rest. 
Transvaal, Pretoria, in February and March (Swierstra). 
Acrocercops aptata Meyr. 
This, which is similar and allied to the preceding, but with the white 
markings larger and more developed, can be immediately distinguished by the 
apical black dot, which is edged above by a small white mark, whereas in 
conflua the preceding white costal mark is remote from the apical dot; the 
costal area is sometimes wholly blackish between the white markings, which 
are all variable, and the apical area is sometimes suffused with dark fuscous, 
but leaving the black dot and white adjacent mark distinct; the two dark lines 
in cilia really form apical hooks as in conflua, but less prominent.
