a small bunch of hair-scales. antennal ciliation, as in the entire group, very short. Sao Thome. The un¬ 
less any other member of the group should hereafter be discovered on the island, can safely be determined by 
its small size and general resemblance to the ^ in markings. ■— sylleptria subsp. nov., reiu’esenting consobrina in sijlippir'ia. 
continental West Africa (Senegal to Nigeria, probably also further south) is darker, the median band fuscous 
instead of dull reddish, a dark subbasal band generally developed on the hindwing, postmedian of that wing 
more acutely angled; costal swelling and tuft slightly stronger than in consobrina. Type a fine from Sierra 
Leone, in coll. Brit. Mus. 
Ch. dexiphyma sp. n. (12 b). Expanse 16—19 mm. Broader-winged than either of the preceding mem- de.r'iijln/iiKi. 
bers of the group, duller or darker than in most of them. Median band of the forewing narrow at the costa, 
irregularly expanding. Forewing with costal margin very strongly convex, with the “nibbled"’ excision (as 
Warren describes it under muscosa) rather deep and concise; hindwing with termen rounded, the terminal 
maculation between the radials almost as strong as on forewing; both wings with dark terminal dashes. Under¬ 
side glossy, infuscated. Principe Island, fine series collected by T. A. Barns and by W. H. T. Tams. 
Ch. peremptata Walk. (12 b). Founded on a $ from Sierra Leone which was evidently in good con- percmpfafa. 
dition when collected but sidisequently broken to jiieces, so that I have had to judge it from head, thorax and 
wings gummed on to a piece of card. I believe, however, that I have correctly determined other from 
the same locality and the Ivory Coast, which agree with it in having the costal margin of the forewing 
faintly swollen at the origin of the antemedian pale band. Hindwing regularly rounded. The type is fairly 
large and does not show conspicuously whitish mid-terminal spots, but these characters are prone to vary. 
By analogy with the sex-dimorphism in iumefacta, I am fairly confident that I have foimd peremptata, in 
a Sierra Leone specimen in the British Museum, unfortunately very much w'orn. If so, it has a similar (or 
somewhat stronger) costal swalling to that of muscosa ' but is smaller and with the concavity in the mar¬ 
gin of the hindwing somewhat shallower than in that form and tumejacia. Possibly peremptata is the oldest 
name for a collective species. 
Ch. muscosa Warr. (12 b). Generally the largest species (or form) in the group, rather variable, but >H».sr-o.s«. 
with the antemedian line characteristically geniculate behind the fold. Costa of forewing with a twisted 
liairy swelling beneath which at first (opposite the middle of the cell) projects sufficiently to show as a slight 
protuberance when viewed from above, then curves downward (opposite the proximal end of the areole), 
suggesting from above a slight “nibbled-out” concavity, finally making a small ridge, which gradually dies 
down. Hindwing with postmedian from the radials to the hindmargin strong, partly marked with blackish 
wedges. Founded on a long series from the Kikuyn Escarpment. — -kampalensis subsp. nov. is somewhat shorter- kampaJen- 
winged, the costal swelling, as viewed from above, showing a somewhat stronger and more proximally placed 
lobe ad its commencement, the hair more mixed with reddish; forewing in the typically less strongly mark¬ 
ed, more olive- grey, the postmedian less strongly dentate in its anterior part; hindwing with the postmedian 
almost equally strong throughout. L^ganda: Kampala (H. Hargreaves), the type (J; Kabale (G. H. E. Hop¬ 
kins), a pair, the $ much discoloured; all these examples have lieen presented to the British. Museum through 
the Imperial Institute of Entomology. Perhaps a separate species, or a race of peremptata. — tumefacta Prout iumejarfa. 
{12 b) is smaller than muscosa (17—20 mm). Forewing in the ^ with the costal lobe and hair-tuft, proximally 
to middle stronger; coloration duller, antemedian line less irregidarly curved. Hindwdng on the whole more 
sharply marked. Fairly common in parts of Natal, particularly the Durban district; known to me also from 
Cape Colony and perhaps Nyasa. Should probably rank as a species. 
Ch. marmorata Warr. (12 b) differs from the muscosa grouji in that the costal lobe of the ^ is opposite marmorata. 
the median band, i. e. at least as distally placed as the proximal part of the areole; the lobe, moreover, is 
chiefly on the upperside of the wing (as is also its distal continuation) and the rough hair-scaling which arises 
from it projects forward and upward. The $$, so far as they are yet known to me, have ahvays a w'ell- 
defined, more or less dark median band on the forewing. Only certainly known to me from Southern Nigeria, 
but I believe I have also seen it from the Ivory Coast. 
Ch. toreumata sp. n. (12 b as ,,tereumata“). No doubt near marmorata, on an average perhaps smaller, foreionota. 
the apex of the forewing more rounded; but remarkably distinct from that and from all know^n species in the 
singular disc-like developments of the costal lobe of the forewdng and the tufts and masses of coarse hair 
which accompany and in large measure cover it. Both upper- and underside participate in these developments, 
but particular attention may be called to a roundish jilate-like flap w'hich is attached to the lobe beneath and 
reaches back nearly to the areole; the cell is narrow'ed to compensate for these costal developments. Forewing 
beneath finely striated throughout, the striae transverse. The extreme V-like angulation on the postmedian 
of the hindwing is inconstant both in toreu7nata and in inarmorata, but less frequent there than here. Comoro 
Islands, general, the type from Anjouan, 29 June 1911 (G. F. Leigh). Also from Madagascar, at least in 
the Tananarive district and at Diego Suarez. I do not known how' to distinguish the $ from that of derasata 
(12 a), unless perhaps the angle of the postmediaii of the hindwdng is more acute.
