M. sematurga sj). n. (12 i). Very distinct; the gibbous-inargined forewing, with reddish, anteriorly .sY-j^cy/t/rr/c/. 
darkened fringe, superficially recalls some Australian Oenochrominae. Structure about as in electa, venation 
of ardescens. The more heavily marked forewing and especially its complex cell-mark are quite characteristic. 
Forewing beneath much paler, excepting the extreme costal edge and the fringe; markings faint, except the 
costal end of the postmedian (aboTit as far as to 1st radial). Hindwing beneath with a curved row of indistinct 
postmedian vein-dots, which fade away behind the 3rd radial. S. Rhodesia; Betsa, 13 April 1918, a good 
submitted by the Rhodesia Museum for determination. 
3. Genus: Acrasia Feld. 
A specialised offshoot of Mauna, scarcely differing except in the al)sence of the long hair of the forewing 
beneath and in a few ^ characters. Hindtibia in that sex without hair-pencil; hindwing curiously contorted, 
the costal region somewhat swollen, this and the middle of the wing above densely clothed with hair, a large 
part of the abdominal margin folded over beneath, the greater part of this fold clothed with specialised, sub¬ 
erect scaling. Only one species know'n. 
A. crinita Feld. (13 b). unmistakable, on account of the structural characters; $ much more like crinifa. 
that of Maima film. Knysna. For many years, the type ^ was the only specimen known, birt recently the 
Transvaal Museum obtained a pair from Hackerville, Cape Province. 
4. Genus: Microligia Warr. 
Less robust than Mauna, with which it agrees in the narrow forewing, long cells and several other 
characters. Face with strong projecting cone. Antenna of the vuth short pectinations; hindtibia not dilated. 
Forewing with 2nd subcostal anastomosing with 3rd—Rh. Consists of a few small, j^ale-coloured species, 
almost exclusively South African. 
M. dolosa Warr. (14 a), the type of the genus, is variable on the forewing, but easy to recognize by doJosa. 
its shaj)e, generally also by the strong oblique grey mark from apex and also a few (more longitudinal) prox- 
imally. Palpus moderate. Cape of Good Hope (the tyjje locality) to the Transvaal, often common. — oriotes oriotes. 
Prout, founded on a single $ from near Bismarckhugel (Kilimandjaro, 2700-—2800 m), is suffused with mouse- 
grey instead of white, though the hindwing remains paler than the forewing. Expanse 28 mm (size of an ex¬ 
ceptionally large dolosa). 
M. luteitincta Front is considerably larger (32—36 mm), the palpus longer, the forewing slightly less tuteiiincta. 
narrow, pale yellowy with no markings except the oblique apical line, which is longer, but slenderer and less 
dark, than the corresponding mark in dolosa. Natal to S. Rhodesia; the originals w'ere believed to come from 
Cape Colony, but this recpiires confirmation. 
M. intervenata Prout (14 a). Intermediate in size between the two preceding; the forewing white, as iniervenata. 
in dolosa (and at least as narrow), but with longitudinal drab streaks betw'een the veins. Face brown, Avhite 
below (in dolosa wholly white). Smithfield, Orange Free State, only the type knowm. 
5. Genus; Argyropliora Guen. 
Agrees in almost all characters with Microligia, but the face is smoother, only with a small tuft below, 
the forewing according to Janse, has a slight fovea and there are some differences — though somewhat in¬ 
constant — in the venation; the 3rd radial and 1st median of the hinchving are generally stalked (sometimes 
q'uite strongly) or are at the least connate; the anastomosis of the 2nd siibcostal of the forewing with the 3rd 
to 4th is slight, often a mere touch or (according to Janse) a close approximation without contact. Type 
species; trofonia Gram. 
A. trofonia Cram. {= histrionalis Westw., trofoniata Guen., monetata Guen.) (14 a). Forewing above trofonia. 
glossy ochreous-brown, with an intricate pattern of white markings; beneath paler and duller, much more 
weakly marked. Cape (the type locality and j^erhaps its chief habitat) to Transvaal. Generally not very variable. 
A. arcualis Westw. (13 b) is, according to the only tw'o specimens know'n to me, somewhat darker, the arcualis. 
dark border of the hindwdng decided, though narrow'. In any case distinct from trofonia in the appreciably 
shorter pectinations, different arrangement of the markings, and lack of white costal edge. '‘Cape” apparently 
rare; IVIr. R. E. Turner took a d'at Milverton, Cape Town in Januar 1926, a second at Mossel Bay in Aiigust 1932. 
6. Genus: Pseuclomaeiias Prout 
The first of a groui? of nearly related, characteristically African genera, to wliich reference has already 
made in the note at the commencement of the Geometrinae, where in the d always, the $ scarcely ever, has
