strong tuft, palpi nearly 3. Antennae dentate on one side, shortly 
unipectinate (1) on the other, strongly bifasciculate-ciliated. Fore¬ 
wings triangular, termen bowed, slightly oblique ; dark fuscous, 
bases of scales grey ; lines fine, brown, indistinct, first from costa 
at | to dorsum at |, straight, second at |, slightly excurved, almost 
parallel to termen ; discal spot slightly darker, very obscure : cilia 
grey, a dark fuscous subbasal shade. Hindwings grey, paler and 
ochreous-tinged anteriorly ; cilia as in forewings.

Bostra chlorostoma, n. sp. 
3 2 • 17-22 mm. Head pale ochreous. Palpi pale ochreous, 
basal half suffused brown, sometimes pinkish-tinged. Antennae 6 
dentate, bifasciculate-ciliated (2). Thorax grey, 5 anteriorly 
crimson-tinged. Forewings rather elongate-triangular, termen 
somewhat obliquely rounded ; light crimson-pink irrorated grey and 
dark grey; lines whitish-pink, slender, rather irregular, first at 
nearly direct, slightly sinuate, second at J, slightly excurved in disc ; 
six or seven obscure pale dots on costa between these; an oval 
blackish-grey discal spot; a terminal series of small blackish spots : 
cilia pale grey, two grey shades. Hindwings pale grey irrorated 
darker, a more or less distinct somewhat excurved whitish post¬ 
median line; cilia as in forewings.

Sacada rhodinalis Hamps. 
Described from a single specimen. I have seen 18 examples 
(all 3 ) of the typical form, taken at Elisabethville, Belgian Congo, 
in November and December ((7. Seydel ); the hind tarsi are 
entirely without the scaletuft supposed to be characteristic of the 
genus, but the species is unquestionably a genuine Sacada on other 
structural characters (palpi and antennae). I have also seen two 
others from the same locality, taken in January and February, 
which I regard as a seasonal form, slightly larger, less crimson in 
tone, greyer and whiter, costa rather whitish-suffused on median 
area, the discal spot narrowed by development of whitish suffusion, 
second line less curved, the light crimson terminal fascia of hind¬ 
wings obsolescent; this should apparently be a wet-season form.
