36. Omphalucha indeflexa sp. nov. (PL I, fig. 12). 
37 mm. Face and palpus black, with a few light scales. Vertex brown, 
anteriorly mixed with black. Thorax above as fore wing, a little rufescent in 
middle, metathorax with well developed double black-mixed crest; pectus 
mostly dark-grey; abdomen variegated with browns, black and whitish. Legs 
ochreous, dotted with blackish, the tarsi mostly blackish with pale ends to 
the joints. 
Fore wing not extremely narrow, but with costal margin faintly concave 
in middle; brown, irrorated with whitish and black, the veins more ochreous; 
cell-mark black, slightly elongate ; lines black ; antemedian strong, from nearly 
one-third costa to hind margin close to base, very weakly curved, slightly 
dentate outward, only the tooth on M at all strong ; median ill-defined, rather 
beyond middle, obscuring the cell-spot, almost obsolete between and M^, 
unless represented by two more proximally placed dashes (on M and SM '^) ; 
postmedian fine, from nearly four-fifths costa to five-sevenths hind margin, 
minutely denticulate outward or thickened on the veins, shallowly excurved 
between the radials, almost inappreciably incurved before and behind; sub- 
terminal line whitish, mostly extremely fine and lunulate, but forming a rather 
large spot in front of and a little thickened between R^ and ; the lunules 
before 5 C® and between the radials filled -in proximally with ill-defined blackish 
spots; terminal line black, rather strong, thickening between the veins; fringe 
dark-spotted at the veins. Hind wing slightly broader than in maturnaria 
Moschl.; considerably whiter than fore wing, especially in anterior part; cell- 
mark strong; antemedian line wanting; median very feeble anteriorly, well- 
defined from cell-mark to abdominal margin; postmedian strong from 5 C^, 
denticulate, slightly incurved between SC^ and R^, otherwise straightish (rather 
less curved than termen) ; subterminal obsolete anteriorly, nowhere con- 
spicuously thickened, narrowly dark-shaded proximally; terminal line and 
spots on fringe strong. 
Both wings beneath whitish, with fairly strong, though not quite uniform, 
dark-grey irroration; cell-spots sharply black; postmedian line of fore wing 
present, but without the outward curve ; median and postmedian of hind wing 
indicated but weak. 
Pretoria North, 26 March 1917 (C. J. Swierstra). Type in coll. Transvaal 
Museum. 
Apart from its shape and colouring, this species is distinguishable at a 
glance from maturnaria Moschl. (= crenulata Warr., Nov. Zool. iv. 90 = hirta 
Warr. op. cit. xii. 397), by the very much less irregular postmedian line of 
both wings. Probably nearer to rufinuhes Warr. {Nov. Zool. xii. 398), from 
Angola, but rather narrower winged, without the rufous shades, the post- 
median line even less incurved than in that species. 
37. Hemerophila (?) ruhidivenis sp. nov. 
$, 43 mm. Head and palpus brown, with some blackish admixture, es- 
pecially on face and outer side of palpus. Palpus rather short. Antenna shortly 
bipectinate, the teeth about 2, becoming vestigial apically. Thorax light 
ochreous brown, above irrorated with red and transversely marked with black ; 
abdomen rather robust, without red irroration. 
Fore wing with costa slightly curved at base and near apex, apex rather 
square, termen waved, anteriorly little oblique, from R^ much more so; cell 
fully one-half, DC^ incurved, SC^’^ moderately stalked, SC^ osculating with 
SC^~^, R^ from before middle, well separate; rough-scaled, brown, irrorated 
with black and glaucous white; the veins reddish, marked with black but
