to Cnemidolophus lavernella, from which it is structurally very divergent. The 
case is an extremely curious one, and I was at first disposed to think the 
resemblance to C. lavernella must be mimetic; the hindwings of Amphipseustis 
are quite peculiar, and the neuration of both wings, together with the basal 
joint of antennae, is strongly suggestive of the Blastohasidae, but I have con- 
cluded that the genus is probably referable here. 
Amphipseustis disputanda n.sp. 
$ 17 mm. Head and palpi whitish. Thorax whitish suffusedly mixed with 
greyish-ochreous. Abdomen stout, dark grey, with whitish segmental margins 
and pale ochreous transverse lines. Forewings elongate, rather narrow, costa 
gently arched, apex rounded, termen very obliquely rounded; ochreous-whitish 
partially tinged with grey; a fuscous irregular-edged fascia from ^ of costa, 
moderate at first but rapidly dilating and extending on dorsum from near 
base to f , with an irregular blackish spot resting on its posterior edge in middle 
of disc; a moderately broad irregular-edged fuscous fascia from f of costa to 
lower part of termen; several small irregular black marginal spots round pos- 
terior part of costa and apex: cilia grey-whitish, with fuscous median line and 
apical shade. Hindwings and cilia pale greyish. 
Transvaal, Woodbush Village, in April (Swierstra) ; one specimen. Not in 
very good order, but so remarkable that it cannot be passed over. 
Ocyphron n.g. 
Head with appressed hairs; ocelli posterior; tongue developed. Antennae 
f , basal joint moderate, with pecten. Labial palpi moderate, curved, ascending, 
second joint with appressed scales, terminal joint f of second, pointed. Maxil- 
lary palpi rudimentary. Posterior tibiae clothed with long fine hairs above. 
Fore wings with 2 from angle, 7 and 8 stalked, 7 to costa, ii from middle. 
Hindwings under i, ovate-lanceolate, cilia i; 2 from rather near angle, 3 and 
4 short-stalked from angle, 5-7 parallel. 
The (7 is as yet unknown, but the genus appears to belong to the group of 
Diocosma, and is perhaps nearest Areocosma. 
Ocyphron oxyphylla n.sp. 
$IT mm. Head, palpi, and thorax light ochreous-yellow. Abdomen whitish- 
ochreous. Forewings broad-lanceolate; light ochreous-yellow, with a few 
fuscous scales; stigmata small, black, plical slightly beyond first discal: cilia 
whitish-ochreous. Hindwings and cilia ochreous-whitish. 
Rhodesia, Umtali, in January (Janse); one specimen. 
Diocosma zarifa n.sp. 
(^14 mm. Head and palpi pale ochreous. Thorax pale ochreous, anterior 
edge dorsally and a bar near posterior extremity crimson-reddish. Abdomen 
light ochreous. Forev/ings elongate, costa gently arched, apex obtuse, termen 
very obliquely rounded; light greyish-ochreous, faintly pinkish-tinged ; costa 
narrowly suffused with crimson, beneath this a subcostal series of two or three 
leaden-grey dots anteriorly, a grey median spot connected with costa by an 
oblique ferruginous mark, and two grey posterior spots; a dark red-brown 
streak from near base of dorsum to beneath a gre}?- subcostal mark at J , thence 
through disc above middle to praeapical blotch, marked posteriorly with three 
small leaden-grey spots, two others in disc beneath first and third of these ; an 
oval ochreous-white spot adjoining this streak beneath at J, edged beneath by
