E. isotenes Prout. At first sight suggestive of a rather narrow-winged, less black-marked dilucida 
(11 b, nigrihasis), with the median area a little narrow’ed, especially aboiit the 1st radial, where the outward 
angidation of the postmedian band is more obtuse. Probably really nearer to semiflavata, the palpus being 
a trifle less elongate than in dilucida, the breast vdth a pale patch in front. Forewing with postmedian band 
complete, but generally quite narrow posteriorly. Hindwing with discocellulars slightly biangulate, as their cen¬ 
tral section is the most oblique; paler grey than in dilucida, scarcely tinged with yellow (not even so strongly 
as in mecodaedala) ; no distinct markings. Moiint Kinangop, with the two preceding. 
E. hemiochra Prout is a little smaller (21 mm), the d' antenna serrate-dentate, with ciliation almost as 
long as diameter of shaft. Wings a little narrower than in semiflavata (11 c), the forewing vdth costal and distal 
margins nearly straight, the latter very oblique, its colour pinkish-buff, the median area rather narrow (at 
least in the (J) and defined by narrow, conspicuous ante-and postmedian stripes, the latter rather sharply angled 
behind the 1st radial, the fringe weakly S]>otted. Hindwing cream-buff, slightly paler proximally than distally; 
some dark dots at abdominal margin; terminal line interrupted. Mount Kenya, at 4000 m. 
E. niedilunata Prout (11 c). Expanse 20—^23 mm. Antenna of with long teeth (rudimentary pecti¬ 
nations), siirmoimted by cilia of nearly their own length. Forewing glossy brown, generally with a tinge of 
reddish and with dark suffusions, characterized by its oblique proximal markings, the antemedian represented 
by lunulate white marks at the base of the 2nd median branch, the fringe with 2 whitish lines. The elongate, 
weakly-marked hindwing is also distinctive. Mount Kinangop, Aberdare Range, 2400—3100 m. 
E. albistillata Prout. Only known from a single $, taken with the preceding at above 3000 m. Ex¬ 
panse 24 mm. Palpus about twice as long as diameter of eye, heavily scaled. Antenna with the ciliation unu¬ 
sually long for a $ (about ^4 diameter of shaft). Breast with a pale patch in front, as in semiflavata (11 c). Fore¬ 
wing fairly broad, the darker bands of the allied species here scarcely indicated, the pale centre of the median 
area shown by paired spots or streaks at costa, at median vein and at submedian, the proximal of each pair 
the whiter and better developed; a further ])air at costa beyond middle; subterminal white line rather broad, 
interrupted at costa and between the medians, extended in celhiles 7 and 3 into longitudinal spots which extend 
on to the base of the fringe. Hindwing glossy drab-grey, almost unicolorous. 
E. orbaria Swmh., founded on a $ from Eb Urru, Kenya Colony is closely similar to dilucida (11 b) 
from adjacent localities, but is somewhat shorter winged, less bright-looking, with the basal patch of the fore¬ 
wing rather less excrirved at the fold, postmedian less acutely bent outward anteriorly. Abdomen Avithout 
white belt. Hindwing with 2nd radial about central, almost continuing the cell-fold; not whitish, though not 
A^ery dark, distal border darker, especially its proximal half. 
E. picturata Warr. (11 c), founded on 2 $$ from the Kikuyu Escarpment, is easily distinguished by 
the grey-tinged median band and the bright reddish-broAAUi siibbasal and terminal bands, the latter broad, 
AA'ith fine Avhite subterminal line in ]Aosterior half, Avhitish midterminal suffusion and indications of an oblique 
AAdiite dash near apex. Termbial line black, interrupted by Avhite vein-dots; fringe spotted. 
E. dissobapta Prout (11 c). Smaller and narroAver-Avinged, Avith heavy hlack markings edging the median 
area of the foreAving, darkened hindAving, etc. Station Perinet, 149 km. E. of TananariA^o, founded on 7 $$ 
collected in October and November 1939. 
E. amphiplex Prout (11 d). Palpus shortish-moderate. Ciliation of (J short (about K diameter of shaft). 
Differs from all other African Eupithecia yet known in the characteristic dark costal maculation of the Avhitish 
foreAving and the soft broAvn band proximal to the subterminal line. Only knoAAii from Kenya Colony. 
E. somereni sp. w. (11 d). (J mrknoAA'n, but a near relationship to aniphiplex may be safely assumed. 
Pal])us similar. Colour light pinkish cinnamon, not AA'hitish; an incomplete faAvn-coloured band proximal to 
the subterminal of the foreAving, strong onlybetAveen hindmargin and 2nd median, a little stronger about the ra- 
dials than aboiAt the medians, obsolete anteriorly; the subterminal itself white, strongest in the same positions; 
besides the strong, elongate black cell-mark, the most conspicuous markings are the costal ones of the foreAving 
alternately punctiform and macAilar, the rather narroAv median area further emphasized by faAvn, black-mixed 
marks at liindmargin. HindAving in part ]Aaler. Nairobi, May-June (Dr. van Someren), 3 $$ in Tring Muse\im. 
E. nabagulensis sp. 7i. (ll d) can hardly be a form of soiuereni, in spite of the strong resemblance. Eore- 
Aving decidedly shorter and broader, hind wing Avith termen straighter from 1st radial hindAV'ard; costal marks 
AA-eaker, except the triangidar one against the cell-mark, posterior marks of foreAving obsolete, both Avings Avith 
terminal “army-brown” band (shown also beneath), containing the subterminal line. Nabagulo Forest, 15 miles 
from Kampala. 25 October—6 Nov'ember 1921 (W. Feather), 1 $ in Tring Museum. 
E. hemileucaria Mah. 17 mm. Eorewing from the apex to the base of the inner margin cut by an oblique 
black line; this line crosses also the hindAving and base of abdomen. The part in front of this line is Avhite, Avith
