with small whitish apical patch, bounded proximally by a distinct brown costal mark. $ much larger, a good 
deal like an overgrown amioniaria $ (52 mm) but with tlie very large cell-spot of atmida $ and witli the median 
area strongly mixed with red-brown. Solwezi, N. Rhodesia, August 1917 (2 and July 1917 (1 $), collected 
by H. C. Dollman and now in tl\e British Museum. 
G. belli 6p. n. (15 e). Similar to aemula in shape and structure, but very much smaller, the cell-mark belli. 
of the forewing pale-centred, the costal spots wanting, the median area broader, browner and better defined, 
the postmedian line irregularly crenulate but without any strong projections. Cerambe, Bihe, Angola, March 
1903 (W. C. Bell), type ^ in the Tring Museum, not very fresh, but easily recognizable. A $, less small (38 mm), 
the median area less broad, has just been received by the same Museum from Gamba, Bihe (R. Braun) and 
shows the antenna to be shortly pectinate. 
G. breviata Prout (15 e). Tongue apparently slight. Antennal pectinations of the d' proximal part hreviula. 
part long. Forewing nearly as truncate as in curticosta (15d) but not quite so broad, midtermen less prominent, 
tone quite different, less glossy, less black-marked, terminal area more contrasted with the rest. Hind wing less 
elongate costally, more whitish, cell-spot wanting above, very small beneath, postmedian above incomplete. 
Both wings beneath with punctiform postmedian. Known from a few localities in Kenya Colony and from 
Birunga; type locality: Kibwezi. 
G. xera Prout (15 e), founded on $$ only, has the palpus rather short, the antenna rather strongly xera. 
serrate, the tongue weaker than in aemoniaria, the sinus between the 1st and the 3rd radial of the forewing 
rather deeper, the 2nd radial arising somewhat before the middle of the discocellulars. Easily known by its 
exceptionally pale colouring and Aveak markings; cell-spot of forewing larger beneath than above, underside 
of hindwing with a small grey cell-spot and very weak postmedian dots. Kibwezi, Kenya Colony; also occurs 
about Nairobi. A more strongly marked $ from Suna, S. Kavirondo, may represent a separate race. A 
from Dire Daoua, recently received, is considerably smaller, slightly narroAver Avinged, the terminal marks in 
part obsolete. 
G. briela Debauche (17 a). The description of this species arrived too late for insertion in sheet 18, Avhere brieta. 
a better position might have been found for it. Antenna slender, Avith the cilia almost 1. Margins more dentic¬ 
ulate than in paliscia, central projection of postmedian line stronger, no subterminal shade beneath. In colour 
rather near integraria, but Avith much less smooth margins and firmer (non-pnnctiform), much more sinuous lines. 
Perhaps related to the much larger, brighter azelinaria (15c). Abyssinia: Mt. Chillalo, ca. 9000 feet, 1 $. 
16. Genus: l^assiiiiia Walk. 
Palpus minute. Tongue vestigial. Antenna pectinate, in the $ only very shortly. Hindtibia Avith all 
spurs. Abdomen of the d slender, of the $ robust. Scaling smooth. Wing-margins not angled; foreAving AA'ith 
1st and 2nd subcostals coincident. A very distinct genus; it has a good many characters in common Avith the 
Palaearctic Dyscia (Vol. 4, p. 407), but differs in its more minute palpus, glabrous femora and the subcostals 
of the forewing. Only 3 species are yet knoAvn, easily distinguishable by their coloration. 
N. caffraria L. {= petavia Cram., petaviaria Hbn., bupaliata Walk.) (17 a). The genotype and most caffraria. 
widely distributed species. It has no yelloAv or orange colouring on the Avings except as a surrounding, narroAv 
or broad, to the dark markings (sometimes so ample, at least in the $$, as to become confluent and form ir¬ 
regular ante- and postmedian bands on the foreAving) and some basal maculation on the foreAving. Cape (loc. 
typ.) and extending northward to Angola, Uganda and S. KaAdrondo. — socors subs'p. nov. has the ground- socor.s. 
colour similar or paler, occasionally almost Avhite, the black dots small, the yelloAv Avhich accompanies them 
very slight, sometimes (perhaps about the cell-spot alw'ays) entirely wanting. All the specimens knoAvn to 
me from S. W. Africa belong to this form; type C from Tsumebi (coll. Brit. Mus.). 
N. Pretoria Prout (17 a). Larger than caffraria, hindwing predominantly orange-yelloAA% its terminal pretnria. 
area concolorous Avith the foreAving; black dots obsolescent; forewing beneath in part orange. Transvaal. 
N. aurantiaca Prout (17a). 34—36 mm. HindAAdng above orange to ternien, foreAving broAAner; AA’ings aurantiaca. 
beneath (except at apex and termen of forewing), reversing the coloration of npperside. S. Mozambique, parti¬ 
cularly about Delagoa Ba 3 L A $ (ab.?) from Zululand, mentioned by Janse under jyretoria, seems to agree 
but has the foreAving avellaneous (underside not described). 
17. Genus: !Palaeoiiyssia T/arrisow. 
Face and the short palpus hairy. Tongue wanting. Antenna of d long and stout, bipectinate, Avith 
very long branches. Thorax and abdomen robust, breast shaggy, abdomen very feebly covered Avith weak
