numerous — misidentifications in Swinhce’s otherwise useful paper (Trans. 
Ent. Soc., Load., 1904, pp. 497-590) and requires a new name : Pty 
chopoda umbricDsta depletiosta, n. subsp. (= minimaria Swinh., 
Trans. Ent. Soc., Lond., 1904, 559, indescr. ; Prout, loc. cit. supra), 
slightly greyer, perhaps less strongly glossy, vertex less white, forewing 
with costa concolorous, fringe with strong dots at base. Founded on 
three $$ (not “ two <J(J, one as given by Swinhoe) in coll. British 
Museum, from Tana River, British East Africa. Warren’s minimaria is, 
as its author says, a close ally of associata Warr. (— exilinota Warr.). 
Ptychopoda ( Cacorista ) rufimixta rufifascia, n. subsp. (PL XXV, Fig. 17). 
Differs from typical rufimixta Warr. (Nov. ZooL, VIII, 207), from 
the Lower Niger, in having the red (in one example more purple) lines 
much better expressed, the median and postmedian distinct across the 
wing, the latter forming a moderate band, proximally blackish- edged in 
at least its anterior half. Hindwing with traces of a red postmedian 
band at least at inner margin, where it terminates m a darkened spot. 
Both wings beneath with conspicuous purple postmedian band, as well as 
•strong suffusion costally on forewing and in cell of both wings. 
Umkomaas, Natal, 2nd January, 1914 (type), 6th January (cotypes 
in coll. L. B. Prout). The British Museum has very worn examples from 
Tonga, British East Africa (wrongly identified by Swinhoe as macrostyla 
Warr.), which seem referable here. 
Zygophyxia, n, gen. 
Face flat, smooth. Palpus short (about as long as diameter of eye), 
shortly rough-scaled. Tongue slender. Antenna in ciliated, in $ simple. 
Pectus and femora glabrous. Hindleg not aborted, tibia in both sexes 
with terminal spurs only. Forewing very long and narrow, costa very 
slightly arched, apex round-pointed, termen smooth, almost straight, 
strongly oblique, about as long as hind margin ; ceil well over one-half, 
C free, a single areole far before end of cell, SC 1 , SC 2 - 4 , and SC 5 arising 
almost together at its apex, or SC 5 from stalk of SC 2 - 4 ; M 1 separate (not 
remote), M 2 rather, near M 1 . Hindwing elongate, costa long, straight, 
apex rather rounded, termen smooth, almost straight from near apex to 
R 3 , then very gently curved, more strongly about M 1 , thence straight or 
faintly subconcave (about parallel with costa), tornus very weak ; cell 
lully one-half ; C anastomosing at a point or rather more, then gradually 
diverging, SC 2 separate, R 2 central, medians as in forewing. 
Type of the genus : Zygophyxia i elictata Walk. (Acidalia ?). 
Differs from Ptychopoda and Limeria in the non-stalking of SC 2 of 
the hindwing ; conscensa Swinh., Proc. Zool. Soc., Lond., 1885, p. 863, 
.though less extremely narrow-winged, also belongs to this genus. 
Zygophyxia stenoptila , n. sp. (PI. XXV, Fig. 18). 
$, 19-20 mm. Face blackish fuscous ; palpus marked with the same 
.above ; vertex and base of antenna pale ; collar somewhat fuscescent. 
Thorax and abdomen concolorous with wings. Light sandy-brown, some- 
times with a tinge of reddish, hindwing very slightly paler than forewing ; 
markings fuscous, rather vague. Forewing with first line obsolete ; median
