May possibly prove to be a form of nitescens Warr., Nov. Zool., IX, 
502 ; rather lighter, the median shade of forewing following the cell-dot, 
the dots in the fringe wanting. Rather longer-winged than consericeata 
Prout, rather less dusted, discal dot of forewmg much smaller and free 
from accompanying grey clouding. 
A rather smaller, rather shorter-winged B from Selukwe, Southern 
Rhodesia, October, 1911 (F. W. Short), and a more typical $ from the 
same source, August, 1913, both in coll. L. B. Prout, seem referable here ; 
also two worn <$<$ from Salisbury, Mashonaland, August and October, 
1900 (G. A. K. Marshall), in coll. British Museum ; $ antennal dilation 
not much longer than diameter of shaft, hindtibia little longer than femur, 
dilated, with light brownish hair-pencil reaching nearly its entire length, 
tarsus quite short (less than one-half tibia), strongly bent. 
Ptychopoda nasifcra, n. sp. (PI. XXY, Fig. 13). 
5, 19 mm. Face and upperside of palpus black. Head and body 
concolorous with wings. Forewing long and narrow, less glossy than in 
the preceding groups, dirty whitish with coarse fuscous dusting, rather 
recalling the Palaearctic Pt. seriata Schrank or longaria H.-Sch., but with 
an appreciably more fleshy tinge ; lines formed of accumulations of the 
fuscous atoms, the postmedian best expressed, antemedian from costa 
at 3 mm. angled on subcostal vein, then wavy, almost parallel with the 
very oblique termen ; median similarly formed, slightly more distinct, 
passing just distally to the black cell-dot ; postmedian from costa nearly 
3 mm. from apex, rather oblique inwards nearly meeting the angle of 
median line, then (at SC 5 ) shapely bent outwards, acutely angled on R 1 , 
thence somewhat sinuous, nearly parallel with termen ; extremely faint 
indications of a sinuous pale subterminal between darker shades ; fringe 
somewhat dark-dotted. Hindwing relatively rather shoH, termen slightly 
sinuate inwards between M 1 and tornus ; no antemedian line ; median 
and postmedian strongly sinuous, the former passing just pioximally to 
the black cell-dot ; a thick dark line distally and parallel to the post- 
median. Wings beneath without distinct markings, except the rather 
large discal dots ; forewing somewhat more suffused than above, hind- 
wing somewhat whiter. 
Warmberg, Transvaal, 9th October, 1903. 
Ptychopoda suhculta , n. sp. (PI. XXV, Fig. 15). 
5, 16 mm. Face and palpus blackish ; head and body otherwise 
concolorous with wings ; forefemur and tibia partly fuscous. Wings 
shaped as in the Palaearctic Pt. biselata or invalida, to the latter of which 
in its small second-brood forms (as I have it from Shanghai) it bears a 
rather near resemblance. Bone-colour, but with a more brownish hue 
than the species named, rather more strongly dark-dusted. Forewing 
with antemedian line from costa just beyond 2 mm., weakly sinuous 
(“ S-shaped ”), reaching hind margin at 1*5 mm.; median shade rather 
diffuse, not very strong, crossing the small distinct black cell-dot, then 
incurved parallel with antemedian ; postmedian finer, gently sinuous, 
with a slight tendency to form small distal teeth on the veins, arising
