to a miich paler obscumta with the postinedian line more projecting in the middle. Antenna of ^ lamellate. 
Cape Town. 
H. minuata Walk. (= hrnnniceps Feld.) (10 k). Still longer-winged, more glossy, the markings of the 
forewing extremely ohliqne. Sexnal dimorphism strong, the $ with conspicuous pale anterior streak as in 
vitalbata of Europe. Distribihed from the Cape to Angola, Uganda and Kenya Colony. 
H. albostriata Facjenst. (11 a) seems to be closely related to minuata, possibly a race. Sexual dimorphism 
similar. Larger, much less brown, the jjrincipal lines strong, the subordinate ones relatively slight. Comoro 
Islands. 
H. suffusa Hmjjs. This South Indian form, which represents the very widely distributed Indo-Australian 
grou]) typified by boarmiata Snell., has been recorded by Janse from Impetyeni Forest and Karkloof (“Nigeria'’ 
is a mis])rint for Nilgiris, the type locality). It will be dealt with in Vol. 12, but as it seems to be established 
in Natal (however introduced) it must be mentioned here. Very variable individually and (especially) sexually; 
the $ nearly always very easy to recognize by some white blotches; the ^ with less white, though some is nearly 
always discernible outside the postmedian of the hindwing, which is more acutely angled than in obscurata. 
Underside with the cell-dots large. Hindwing with the distal margin strongly creniilate. 
22. Genus: £u|>itlieeia Curt. 
A nearly cosmopolitan genus of small moths which are generally well characterized by their shape 
and by their genitalia (see Vol. 4, p. 274), althongh some of the other morphological characters are someAvhat 
inconstant. Palpus moderate or elongate. Antenna of c? generally ciliate or almost simple. Abdomen with 
a series of small crests. Forewing with distal margin relatively long, strongly oblique, areole double or simple. 
Hindwing relatively small, discocellulars rarely biangulate, 2nd radial aboi;t central. The African species are 
still very imperfectly known, their biology hitherto almost entirely unknown; with the exception, perhaps, 
of the more glossy-winged dilHcida-gxow]}, they seem quite nearly related to those of the Palaearctic Region. 
A. Section Eucymatoge Him. Areole double. 
E. pretoriana Prout (11a). Forewing with costal and distal margins less elongate than in most of the 
species. The one which most resembles it, both in shape and markings, is connexa IFarr., which has the areole 
undivided and is not known from the South African subregion. Pretoria. 
E. subcanipars Prout (11 g). Our figure gives a good idea of the shape of the species, but is not suffi¬ 
ciently variegated; the colours are nearly those of variegated ])En'piuellata Him. (Vol. 4, pi. 12 d) but their 
arrangement is very different, the greyish scaling being placed chiefly in and beyond the cell of the forewing. 
Transvaal: Pilgrim's Rest. By a misprint, the type was pid)lished as 
E. coaequalis Janse (11 b). Closely like subcani‘pars, the areole similarly double. Abdomen Avith much 
darker clouding dorsally. Forewing less rufescent, the markings stronger and more uniform in expression, 
showing some tendency to strengthen at costa, the hoary patch wanting. Hindwing rather whiter, at least 
anteriorly. Underside perha])s somewhat more sharply marked. Until the E structures have been compared, 
I cannot feel sure that it is not a subspecies. Palpus longish-moderate. E antennal ciliation very short. S. 
Rhodesia; Bulawayo and Umvuma. 
E. thessa sp. n. (11 b). 19—20 mm. Face with slight cone below. Palpus nearly U/i times diameter 
of eye. heavily scaled, mostly fuscous-mixed, the base pale. Antenna of with the ciliation less than y.y dia¬ 
meter of shaft. Abdomen above with 1st segment pale, the rest much mixed AA’ith red-brown and fusco\is. 
Forewing with areole generally divided, biit variable (the proximal areole in 1 ^ quite small; in the type E 
still smaller on the left wing, on the right apparently wanting; in the other $$ of normal size); pale drab-grey, 
more or less suffused with drab; cell-dot minute; lines mostly Aveak, formed of interrupted dark irroration, 
those in the centre of the Aving excui’A-ed betAAeen the median A^ein and the sid)median; postmedian line fairly 
AAell deA^eloped from 1st radial to 2nd median; terminal area darker than the gronnd-colour; subterminal line 
forming an irregular W in front of the 1st radial. HindAving Avith termen not quite regularly rounded, being 
very slightly ])rominent at the 1st and 3rd radials, 1st median and 2nd sidnnedian and a little straighter in 
the radial and submedian areas; markings mainly rather weak. Underside glossy, hindAving paler than foreAA'ing; 
cell-dots better devehqAed; costal s])ots or dashes at the beginnings of the lines; lines generally continnous, the 
})ostmedia7a and the divided jjale band outsifle it best developed. S. Africa; Kastrol Nek, January (G. a*AX' Dam), 
1 3 $$; type in Transvaal MuseAim. The sha])e, miiiAite cell-dots, etc., readily separate this species from 
pretoriana. 
E. rigida Sivinh. is a A-ery A\idely distributed Indo-Australian Eupithecia and AA'ill be dealt AA'ith in 
Vol. 12. — sporadica Proa* (11 h) has the postmedian line of the foreAving somexA hat less shaiqily bent, the Avhite 
costal mark outside it single (in r. rigida nearly ahA’ays doiilde), hindAA'ing A\'ith the doAd)le pale mark on the
