Cohcleora. Exjianse 49 — 51 min. Antenna of (5* pectinate to jnst beyond Forewing with terinen relatively 
shorter, hindwing wdth abdominal margin relatively less long, than in expcmsa; more clouded; markings olive 
drab, somewhat strengthened at costa, antemedian rather thick and blurred, partly confluent with the straigh- 
tish, r a t h e r ]) r o x i m a 11 y place d median; postmedian strongly dentate; iiosition of subterminal in- 
flicated by interrujited proximal maculation. Underside scarcely irrorated, the markings faint. Ruanda; Ru- 
gege district. 7000—8000 feet, December 1921 (T. A. Barns), a pair in the British Museum. 
C. polysemna Sj). n. (16 d). In shape and structure near the preceding, hindwing slightly more dentate; 
foretibia more strongly tufted, 1st and 2nd subcostal longer-stalked, the stalk anastomosing with costal, 1st 
radial stalked with 3rd—5th subcostal; antenna ]}ectinate to little beyond middle. A conspicuously lage 
species. Brown in varied hues, noticeably paler and more buff in the middle of the area between the postmedian 
line and su1)terminal shade; veins largely white, minutely dark-dotted; some irregiclar white patches; ante- 
median weak, the other lines indicated by minute dashes on the veins, the postmedian developing a V-mark 
on 1st radial. W. Kivu: Upper Lowa Valley, near Masisi, 5000--6000 feet, forest and long grass. February 
1924 (T. A. Barns), the ty 2 )e (J only, ex coll. Joicry. 
C. pulverosa Warr. (= contemptaria Janse, nec Walk.) (18 b). A species of cpiite uncertain affinities, 
but fitting less badly here than in Henierophila, in which it has been jjlaced. In coloration and pattern there 
is a marked superficial resemblance to the tyjjical section of Ectropis (see Vol. 4, p. 376) except that the dark 
marks just outside the middle of the postmedian line are wanting; but. apart from the narrow valves, I can 
see little in common structurally. Paljnis in the $ short, in the d' I’ather long — an usual sex-dimorphism 
which long hindered the correct determination of the latter, IVarren having described from the larger, more 
weakly maiked, more expansaAWe 5. Antenna of (J ])ectinate to near the ti]), with very long branches. 
Tongue slight. Foretibia heavily clothed but not hairy. Fovea undeveloped; 1st and 2nd sidjcostals in the ^ 
free, in the $ long-stalked. Described from Natal, where the larva feeds on Ochna atropurpurea. Known to 
me also from Nyasa, Tanganyika and Kenya. 
C. suffumosa sp. n. (J, 39 mm. Much darker than ‘pulverosa, the wings being copiously and almost 
unifornfiy irrorated with dark-grey (tone perhaps of a not very extreme Ectropis crepuscularia ab. clelamerensis 
B.-White. Vol. 4, p. 376). Palpus short. Pectinations not quite so extremely long as in pulverosa. Foretibia 
densely clothed, but with the hair apju’essed; midtibia rather more loosely haired (hindlegs lost, but clearh" 
not dilated — no abdominal s])ine). Forewing with first two subcostals free; costa less rounded than in p«/yero5a, 
still more recalling Ectropis. Markings ap]>roximately as in pulverosa; postmedian rather firmer, slightly more 
incurved behind the middle; sid^terminal and its shading weaker. Underside somewhat less dark, not irro¬ 
rated; cell-dots (spots) and imstmedian present, not intense, the latter arising from a small costal spot. Angola; 
Gamba. Bihe, Dec. 1934 (R. Braun), a good d* in the Tring Miiseum. 
C. perpectinata sp. n. (16 b). d', 34—40 mm ($ unknown). Very much like icUocliroa Front, which, 
pending a more scientific revision, remains in Boarmia (sens, lat.) but is jrrobably related. Palpus similar (well 
beyond diameter of eye, densely scaled), tongue probably a little more slender. Antenna Avith the pectinations, 
even of the inner series excessively loirg, leaving free at its apex less (in idiochroa more) than 1 mm. Goloration. 
AA’ithout the reddish influence. Forewing with 1st and 2nd srdjcostals shortly stalked, lines more bent near costa, 
the postmedian oblique o u t av a r d in crossing the 5th sidrcostal. HindA\ ing AA’ith median shade dentate 
outAvard about the median A^ein. Underside Avith subterminal maculation generally stronger than in idiochroa. 
The legs are nearly smooth-scaled, though fresh specimens sIioav a little hair on the fe]nora. ^Madagascar; 
Perinet, 149 km E. of Tananarivo (N. and G. Olsoufieef), a good series in Mus. Tring; TananariAm, 3 (Iaao 
of them large) (Coll. Dr. G. E. Audbouu) ; Ambinanindrano, W. of Mahonore, 3 rather small (Kestkll-Cornish). 
C. proximaria Walk. (16 e). This and the folloAving, though so closely related to one another that they 
might have been mistaken for SAibspecies, have an aspect apart from that of all others. Janse finds its genitalia 
not incompatible generically AAuth those of divisaxia, but it has not the hairy foreleg, Avhile its more rounded, 
Avhitish wings more recall pulverosa. Face and pal]5us short. Antenna about as in pulverosa. Hiudtibia AvithoAit 
pencil. Cell long; fovea well developed. First tAvo subcostals moderately stalked. The Auiderside is rather strik¬ 
ing: cell-spot on each Aving roundish, sharply black; costa of foreAA’ing AAith a sAd)apical Ifiackish s]iot, the apex 
itself purer Avhite than the rest of the AA'ing. The ty])e form, from Natal, is distributed locally from E. Griqua- 
land to S. Rhodesia. Mr. E. E. Platt, of Durban, has bred it from lainme found on Albizzia and Acacia. al¬ 
bescens Front, from E. Africa (Kenya and probably Tanganyika) is considerably Avhiter and on an av'erage 
smaller. 
C. grisea ./unse (18 a) has the transverse markings much stronger, the dots connected into lines, the 
median shade sometimes very heaA^y. Underside, in addition to the characteristic maculation of proximaria. 
AAdth at least indications of the transverse lines or bands, particularly the subterminal. S. Rhodesia.
