Mombasa Island. 1 have seen a few similar forms (conspecific ?) in jjoor condition from several distant localities 
in continental Africa. 
Ch. dietzei Bastelh. (Hi) may well be a form o? grisea. Forewing narrow, elongate, with strongly j)ro- 
duced apex, hindwing with both angles almost rectangnlarly curved, termen with appreciable concavity; yellow- 
brown, tinged with olive-green, cell-mark of forewing elongate, oblique, the Vn’oad pale, bisected band se])a- 
rated from the gronnd-colour by 2 dentate dark lines. The type (a $) is from ‘Tto, Mozambique'’ (I believe 
a njisprint for Ibo). 
Ch. viridigrisea sp.yi. (Hi). Expanse 15—18 mm. Differs from grisea in its slightly broader wings, firidif/rinca. 
olive-green tint (easily fading to dirty yellowish) and stronger subterminal line; which on the underside be¬ 
comes a conspicuous pale band, dividing into two unequal parts the broad dark distal area which in grisea is 
almost solid. Sao Thome, November 1932 (W. H. T. Tams), 2 10 $$, collected for the British Museum. 
Antenna of the cJ better ciliated than in grisea, nearing half the length of the diameter of the shaft. 
Ch. mokensis s-p.n. (11 i). Expanse 15—16 mm. Likewise somewhat broader-winged than grisea, the mokcnms. 
d' antennal ciliation less rudimentary, the sinuosities of the margin of the hindwing more pronounced (which 
is not the case with viridigrisea), that of the forewing also ajjpreciably more irregular. A rather dark species, 
especially in the median area, thus recalling Gymnoscelis hirivulata (11 m) though not quite so small. The suf¬ 
fusions are red-brownish, not greenish, the distal area with more extended dark cloudings than in viridigrisea, 
the postmedian line of the hindwing more irregular, the subterminal line l^eneath miich less developed. Fer¬ 
nando Po: Moka, 28 January—-3 February, 1933 (W. H. T. Tams), 2 d'c?) 1 $• 
Ch. consocer sp. n. (11 i). Very similar to grisea and of about the same size, or on an average a little mnsocer. 
smaller. Structure closely similar; hindwing slightly more prominent behind the sinus, which therefore appears 
somewhat more consjhcuous. Colour more greyish, the distal area of the forewing more uniform, scarcely 
showing the dark markings near costa and between the radials; median area generally with some rosy suffu¬ 
sion; postmedian line less dentate outward at the 1st radial; postmedian of hindwing less bent outward at the 
3rd radial. Transvaal, Natal and Transkei, the type $ from Pretoria North, in my collection. Unfortunately 
consocer was misidentified in the British Museum as consohrina and in consequence got determined in the Trans¬ 
vaal collections as "'consobrina V’ so that Janse has dealt with it under that name. He has described the A 
genitalia and calls attention to the oblique course of the lines of the forewing as distinctive. 
Ch. leighi sp. n. (11 i). A little larger than ejrisea, the termen of the forewing slightly more oblique, its leighi. 
postmedian a little more strongly angled about the 1st radial, thereafter straighter, the sinuosity of the termen 
of the hindwing rather more pronounced, postmedian with less strong j^rojections, underside a trifle ])aler and 
(especially on the forewing) with a distinct dark Giibterminal band in addition to the markings of grisea. Grande 
Comoro, August 1921 (G. F. Leigh), a series of 12 in the Tring Museum, one labelled as bred, but with no in¬ 
formation regarding the earlier stages. Smaller forms of the same or a similar species, mostly in de])lorable 
condition, were collected in abundance at Diego Suarez by G. Melou. 
Ch. jansei sp. n. (= grisea Janse, nec Warr.) (11 i). Larger than grisea, of which the largest known jaasci. 
specimen (a $) has a forewing-length of only 7 mm, while in the smallest ja nsei known to me it reaches 8 mm. 
Palpus relatively shorter, scarcely reaching beyond the frontal tuft. Abdomen with a dark belt at base, of 
which there is no trace in grisea and leighi. Coloration and markings suggestive of the latter, except that the 
postmedian on each wing has 2 nearly equal projections; distal areas, both above and beneath, more strongly 
marked than in leighi-, the subterminal perhaps less deeply dentate (few grisea, however, show it really well 
developed). Good structural figures are given by Prof. Janse in his fine work on the Moths of 8outh Africa. 
Transvaal; Barberton, Materval Onder and Pilgrim’s Rest; also known from Port St. Johns; type from 
Barberton in my collection. 
Ch. gymnoscelides Prout (Hi) is probably related to the four preceding, but shows a vinaceous ad- ggnino.^tr- 
mixture which gives it nearly the colour-combination of the European Gymnoscelis pumilata Hhn. Hindwing 
with termen smoother than in grisea ; forewing of the with costa shouldered at base, here edged with nume¬ 
rous small hairs. Forecoxa in the ^ covered with a patch of very broad metallic scales. I’alpus about as in 
grisea. Natal (type) and Three Sisters, Transvaal. Perhaps very widely distributed, as a $ from Bibianaha, 
Gold Coast, seems to agree very accurately vith it. 
Ch. dentatissima Warr. nigrilineata Warr., nom. praeocc.). Distinguishable by its light yellow- dodalissi- 
brownish colour, absence of definite distal boundary to the pale band which succeeds the postmedian, approxim- 
ated costal spots at the origin of the lines which bound the median area of the forewing, sudden widening 
of that area through the strong outward curve cf the anterior part of the postmedian, and vein-dashes on the 
postmedian which give it a strongly dentate appearance. A very widely distributed island species, Ceylon 
to Australia and some of the Bismarck group. In Africa only known from New Hanover, Natal; I saw one
