to the termen ; a terminal blackish line, interrupted at the veins ; black spots 
on fringe opposite the veins. Hind wing with termen very faintly waved from 
hindwards, very slightly more prominent at SC^-K^ stalked for well 
over one-half their length; cell shorter than on fore wing, markings more 
proximal, antemedian line wanting. 
Fore wing beneath with the ochreous costal edge rather broader, otherwise 
smoky (near base with some black irroration), with only the postmedian and 
terminal lines developed and these not very strong; spots on fringe weak. 
Hind wing also somewhat smoky, especially beyond the postmedian line, 
which is here fairly sharp. 
South Rhodesia: Salisbury, 16 September 1917. Type in coll. Janse. 
19. Ptychopoda carneilinea sp. nov. (PI. I, fig. 25). 
9, 20 mm. Face and outer side of palpus black. Vertex and antenna white. 
Thorax and abdomen whitish-brown. 
Fore wing with apex moderate, termen smooth, oblique, gently curved in 
middle; brown-whitish with a slight tinge of pink; costa basally rather more 
brownish; a few scattered black scales; lines flesh pink; ist obsolete; cell-dot 
very small, black ; beyond it a rather thick, straight median line, slightly more 
oblique than termen, becoming obsolescent at costa; postmedian about 1*5 mm. 
from termen, extremely fine, marked with very small black dots on the veins ; 
two subterminal lines, thicker, but not so strong as the median, very feebly 
lunulate behind middle, otherwise straightish; termen with weak grey line, 
interrupted at the veins; fringe with minute black dots at base, opposite the 
veins. Hind wing with termen faintly waved, very slightly bent at R^;SC^-R^ 
stalked for half their length; slightly cleaner white than fore wing; markings 
the same, but with the dots on postmedian line and especially the cell-dot 
larger, the median line proximal to the cell-dot, slightly incurved in cell, the 
postmedian fully 2 mm. from termen, with the usual sinuosities more notice- 
able. 
Underside similarly but more weakly marked, the fore wing slightly pinker, 
the hind wing slightly whiter. 
Cape Town, March 1912 (Lord Gladstone). Type in coll. Transvaal Museum. 
20. Ptychopoda umbricosta Prout. 
This is evidently a very variable species, unless, indeed, we have really 
to do with a group of distinct species with the same characteristic structure 
and general facies. In addition to the form punctigera Prout and the East 
African subspecies depleticosta Prout, already described, two other well-defined 
forms are now known to me; these I describe as follows: 
f. omoscotia form. nov. $, 17-18 mm. Larger than typical umbricosta, the 
hind wing appearing slightly fuller, chiefly on account of a slightly stronger 
projection in the distal margin at R^-M^, both wings with minute but distinct 
black cell-dot above and beneath. 
Fore wing with the costal margin not reddened, at most very slightly 
browner than the rest of the wing, on the other hand with the lustrous leaden- 
grey scales (which, though scarcely distinguishable without the lens, give to 
the whole wing its peculiar gloss) strongly accumulated at base of costa and 
here mixed with dark fuscous. Both wings with vestigial transverse lines 
indicated, much as in f. punctigera Prout, their actual and relative intensity 
varying according to the individual. Both wings beneath with the lines well 
expressed and mostly with rather strong irroration between the postmedian
