7. Genus: Slebclomoplirucla IVarr. 
In its elongate wings, generally with still longer cells, and in its (hdl, sober coloration a marked 
contrast to Psetulomaeiias, yet differing hnt little in essential stnictnre. Antenna in Imtli sexes ]>ectinate, the 
branches moderate or rather short in the (J, qixite short in the Janse distingnishes it from both P.setido- 
maenas and Drepanogynis (sens, lat.) by the cessation of the pectination before the apex, of the antenna, hnt 
this seems to me to apply to the $$ only. Ihxlpus on an average less elongate than in Pseudomaenas. Excln- 
sively South African. 
H. curvilinea Warr. (14 b), the type of the genus, was founded on 4 from Weenen. Natal, and cim-Uinca. 
has since been taken in some localities in Cape Colony and the Orange Free State. Costal margin of forewing 
almost straight, or inclining towards concavity. The simple marking of the forewing and the whiter hindwing 
distinguish it from the rest of the Hebdotiiophruda. 
H. apicata ITarr. (14 b). Also from Weenen (Warrek's type), but, so far as I known, not since ob- apicata. 
tained there; the Tring Museum has also a from Grahamstown and the British Museum 2 from Miss 
F. Barrett (probably from Transkei). Forewing more glossy and less irrorated than in curvilinea, with an 
apical dash, the oblique line sharper than that of curvilinea, but accompanied by some slender dark shades 
which make it appear hi- or tripartite. 
H. crenilinea Prout (14 b). Close to apicata, possibly representing it in Orange Free State and Basuto- crenUinPu. 
land. Middle segments of abdomen strongly infuscated; oblicpre markings of forewing waved or cremdate in¬ 
stead of straight, some srdrordinate markings, both here and on the hindwing, better developed. 
H. errans Prout (14 c) is smaller, the (J pectinations a little shorter and stouter, the postmedian line ermns. 
arising from costa, not a])ex,but more oblique than in the succeeding three species, in which this is also the case. 
Hindwing well marked. Fraserburg, Cajxe Colony (type) and Bushmanland. 
H. eupitheciata Warr. (14 c). There has been some confusion regarding this species, on which was enpUhe- 
founded an unnecessary genus Stenoptilotis Warr., but it is certainly a Hebdomophruda. The one here figured, 
with its larger cell-dots, ill-defined lines above, rather bright red-brown terminal area (beneath more vinaceoixs) 
and somewhat longer pectinations (particxilarly in the $) seems to agree better with the description than does 
the following. The original, a $, came from Smithfield; besides, I known, only a few from Cape Colony 
(Willowmore, Dunbrody, etc.). 
H. diploschema Prout (14 c). Very similar to the preceding, but less bright. The slender black lines dlpto- 
of the forewing are interrupted at the fold but connected with one another by equally fine lines before and 
behind the interruption. Founded on 2 $$ from near Beaufort West, Cajxe Colony; both sexes have since 
been obtained at Willowmore by different collectors. 
H. sculpta Janse (14 c). Hindwing scarcely so narrow as in the two preceding; its postmedian line much sculpia. 
more proximally placed than in errans. Forexving with median area a good deal infuscated, differently sha])ed, 
the antemedian line acutely angled outward in cell, the postmedian at first (for a longer distance than that of 
errans) nearly parallel with distal margin, then curving to become extremely (though not qinte regxilarly) oblique, 
the median area in consecpience over 3 times as broad at costa as at hindmargin. I only know it from the 
type locality, Willowmore (Cajxe Colony), but it is also recorded from Bloemfontain. 
8. Genus: llrepaiiogyiiiis Guen. 
Drepanogynis is the oldest name for the collective groxxp which has already been in part discussed xmder 
Pseudomaenas; and as some of its elements are in a measure connected by intermediates and the genitalia 
“show an amazing uniformity, hardly to be expected among species which differ so greatly in general appear¬ 
ance”, Janse has proposed to unite almost all except Pseudomaenas and Hebdomophruda (it is not quite clear 
why these were not also included) in one comprehensive genus. I prefer for the present to retain the principal 
“subgenera” as genera and to employ Drepanogynis for those in which the head and femora are not or scarcely 
hairy, the wings fairly broad, the forewing with a])ex generally acute or prochiced, the hindwing with the costa 
not specially long, the costal vein diverging from the cell aboxxt its middle, the palpxxs not long, the missixxg sxxlx- 
costal veixi (as also in the two preceding genera) apparently the 5th. Even so, Drepanogynis is sxxfficiently 
heterogeneoxxs in shape and pattern, in the details of the antennal strxxctxxre, etc. In any case Dissodes IForr. 
is an absolute synoixyin, having the same genotype (mixtaria Guen.), and Apleroneura Warr. (type tripartita 
Warr.) and Phrudochorda Warr. (type juscimargo Warr.) at nxost a section (or sections) with pectinate $ antenna. 
A. Antenna in both sexes h i p e c t i n a t e {Apleroneura) (see also the last 3 doxibtfxxlly 
placed Drepanogynis).
