Lasiomactra n.g. 
Head loosely scaled, sidetufts raised, spreading; ocelli posterior; tongue 
short. Antennae f , in stout, serrulate, somewhat compressed, simple, basal 
joint moderate, without pecten. Labial palpi very long, recurved, second joint 
thickened with dense appressed scales, expanded at apex above, terminal joint 
as long as second, densely scaled and with loosely projecting hairs posteriorly, 
pointed. Maxillary palpi rudimentary. (Posterior legs missing.) Forewings 
with 2 and 3 approximated from angle, 7 and 8 stalked, 7 to apex, ii from 
middle. Hind wings i, elongate-ovate, cilia f; 3 and 4 connate, 5-7 nearly 
parallel. 
Allied to Cryptolechia. 
Lasiomactra acharista n.sp. 
c? 18 mm. Head, palpi, and thorax ochreous-whitish, second joint of palpi 
tinged with grey. Abdomen light yellow-ochreous, segmental margins and 
anal tuft whitish. Forewings elongate, costa gentl}^ arched, apex obtuse, 
termen obliquely rounded; ochreous-whitish: cilia concolorous. Hindwings 
ochreous-whitish, slightly more ochreous-tinged posteriorly; cilia ochreous- 
whitish. 
Portuguese East Africa, Magude, in December (Swierstra); one speci- 
men. 
Erotis hesperanthes n.sp. 
$ 16 mm. Head loosely rough-scaled on crown, ochreous-whitish, speckled 
on crown with blackish. Palpi whitish, second joint speckled with black to- 
wards apex. Thorax pale ochreous tinged with rosy- violet and speckled with 
blackish. Abdomen ochreous-whitish sprinkled with grey. Forewings elongate, 
costa gently arched, apex obtuse, termen very obliquely rounded ; light crimson- 
rosy, thinly sprinkled with blackish ; some undefined obscure brownish-ochreous 
suffusion, more blackish-sprinkled, extending from base of dorsum to middle 
of disc, and over most of posterior half of wing except towards costa ; a rather 
thick purple blackish-sprinkled streak extending along posterior third of costa 
round apex and upper part of termen: cilia ochreous-yellowish, tinged with 
rosy towards base, and slightly sprinkled with blackish. Hindwings light grey; 
cilia light greyish-ochreous. 
Rhodesia, Umtali, in January (Janse); one specimen. The only other 
species of the genus is from Ceylon. 
Amphipseustis n.g. 
Head with appressed hairs, sidetufts loosely raised ; ocelli posterior ; tongue 
developed. Antennae |, basal joint moderate, rather stout, flattened, with 
strong pecten of oblique scales. Labial palpi moderately long, curved, as- 
cending, second joint thickened with dense loose rough hairscales beneath 
projecting at apex, terminal joint f of second, slender, acute. Maxillary palpi 
obsolete. Anterior tibiae thickened with loose rough hairscales (middle and 
posterior legs missing). Forewings with 2 from near angle, 2-5 rather curved, 
7 and 8 stalked, 7 to apex, 9 and 10 from near 7, ii remote, from before middle 
of cell, long and approaching 10 towards costa. Hindwings i, elongate-ovate, 
cilia f ; 2 remote, 3 from well before angle, 4 and 5 stalked from angle, 6 and 
7 parallel. 
An abnormal form, apparently intermediate in relationship between Erotis 
and Cnemidolophus , in structure more approaching the former, to which it 
could be regarded as ancestral, but in superficial appearance extremely similar
