GONODONTIS. By L. B. Prout.

G. noctuodes Warr. (15 d), on which was founded a supei'fluous genus Buttia, is rather smaller and noclunrJcfi. 
much darker than 'per])lexata (15 b), the pectinations a little shorter and stouter, the apex of the forewing less 
acute, the postmedian line on both wings more deeply inbent between the radials, the cell-mark of the hind¬ 
wing small and weak, the forewing beneath more suffused and weak-marked, the STd)terminal shade of the 
underside wanting. Foot of Nieuwveld Mountains, only the type known. 
G. paliscia Prout in a measure links the preceding group (in which the anterior part of the termen of ixtlisr'ia. 
the forewing is only waved, or in homales cpiite smooth) with erebaria, which definitely approaches the shape 
of the more typical Gonodontis of the Palaearctic Region. Larger than erebaria (about 44 mm), pectinations 
longer, crenulations of termen slight, irrorations and cloudings of forewing strong, dark fuscous, in ])articular 
a band-like proximal shading to the postmedian (in this and the form of the antemedian line recalling Crocallis 
boisduvalaria, Vol. 4, pi. 15 g); postmedian twice incurved, i. e. at both folds. Hindwing above comparatively 
pale, the cell-si^ot shadowy. Underside strongly marked, the ])ostmedian of the hindwing thick, lunulate- 
dentate, with a dee]) V-shaped angle inward at the radial fold; dark shades of outer area present, interrupted, 
on the forewing anterior only, but extended to the apex. Stellenbosch, Cape Colony; also Cape Town? 
G. erebaria Crfiiew. (15 c). Distinguishable from all the other South African Gonodontis (unless indecoraria erebaria. 
is a sj)ecies) by its shape and tone. The original expanded about 40 mm, but most of the known to 
me are considerably less (down to 34 mm). Forewing beneath not strongly marked, but showing the ill-defined 
beginning of a brown subterminal band, reaching about to the 2nd radial. Pectinations moderate (3 or 4 times 
diameter of shaft). Cape (loc. typ.) and Pondoland. Variation not great, but puzzding, consisting in the form 
of the lines. The (generally very weak) antemedian commonly runs tolerably direct from costa to the bend 
at the fold, but sometimes it is bent (or bluntly angled) ab both folds (as in ab. ? indecoraria)-, the degree 
of sinuosity of the postmedian also varies. — ab. (?) indecoraria Walk., a worn from “S. Africa’’ (Cape) is indecoraria. 
rather dark, except terminally, and has the antemedian as noted above, the postmedian so nearly straight that 
I first thought it should be a species, but intermediates perhaps occur; the termen also seems slightly less den¬ 
tate than in erebaria. A d' from Stellenbosch has the same postmedian, b)it is not so dark and has the ante¬ 
median only once bent (at fold). The genitalia show no tangible differences, but there may be some in the 
number of pectinated antennal joints. 
G. craterias s-p. n. (15 d). Only known from the $, which — like that sex in erebaria and some others — craierias. 
has the teeth of the distal margin of the forewing stronger than in Gonodontis SS of this group. Both wings 
rather narrow, the forewing with fuscous suffusions, much as in p)dLliscia, both wings with rather strong irrora- 
tion, that of the forewing blacker; the conspicuously black cell-spot of the forewing gives it a distinctive ap¬ 
pearance, otherwise the markings are similar to those of erebaria but more angular, the antemedian with a 
strong tooth outward in the cell in addition to the submedian curve or angle. Arusha district, Tanganyika

and blunt in the sharp in the $ (as is also the apex). Red-brown, more fuscous in the d', the principal veins 
lighter; antemedian line obsolescent in the G, better expressed in the $; postmedian straight, whitish, )inusually 
distally placed; terminal dots rather large. Forewing beneath paler and greyer as far as the postmedian, costally 
and distally tinged with cinnamon-buff, cell-mark weak, a white or light-grey apical spot; hindwing rather browner 
than above, cell-mark and postmedian strengthened, the latter especially on the veins. AV. Kivu: Lowowo

but with the veins less strongly differentiated, terminal dots weaker, cell-spots somewhat enlarged, line of 
hindwing bent before reaching hindmargin. Mt. Cameroon: Musake, 6350 feet, January 1932 (Miss i\I. Steele),

G. ochroneura sp. n. Expanse 46 mm. In structure and coloration close to acyrthoria. Forewing slightly ockroncura. 
greyer, the distal area also somewhat suffused with grey, therefore less strongly contrasted; veins rather sharply 
pinkish-buff; antemedian line white, very slender posteriorly, less so anteriorly, at costa 5 mm from base, 
strongly oblique outward to middle of cell, slightly less so to median vein, excurved between this and 2nd sub¬ 
median, strongly oblique inward to hindmargin at 6 mm; cell-mark as in azelinaria (15 d); postmedian fine, 
less near termen than in acyrthoria, more sinuous; terminal dots weak; fringe clouded with grey. Hindwing 
as in acyrthoria or slightly darker. Underside with the veins more brightly buff than in acyrthoria, distal area 
of forewing scarcely differentiated; postmedian line strongly punctiform, on the hindwing crenulate and Avith 
slight curve inward between the radials and prominence at 3rd radial. W. Kivu: Middle Lowa Valley, near
