Ch. subcomosa Warr. (12 c and $). The $ is easily distingiaished from those of the rest of the group 
by the particoloured median band of the forewing, generally reddish (occasionally more fuscous) as far as fold, 
green behind. The shows the same colour-scheme on the forewing, but is again remarkably specialised, forming 
the ‘'genus" Mesocolpia Warr. Besides the long, stiff midcostal fringe and the peculiarities of shape, which 
may be seen from onr figure, the underside is very noteworthy: forewing mostly striated, much as in forew- 
raata ; hindwing with costal region expanded, cell very short, the region distally to it partly nacreous, puckered 
and contorted, terminally (especially near tornus) tufted, anterior part of termen with some specialised scaling. 
Sao Thome, the d' very rare, the $ rather less so. 
Ch. exilipicta J. Joan. (12 c). A pretty and —■ so far as the African fauna is concerned —■ unmistakable 
species. I have recently descril)ed from Fiji a very closely similar species which will be dealt with in Yol. 12. 
Although much less specialised than most the preceding group, exilipicta (J has a costal fold on the under - 
side of the forewing, proximally fringed with hair-scaling. Hitherto only known from Mauritius; I have found, 
however, a $ from Reunion in the Oberthur collection. 
24, Genus: Camelopteryx Joav. 
Antenna of ciliated. Hindtibia with all spurs. Abdomen with small crests. Forewing of with a 
strong convexity before middle of costa, apex rounded; venation nearly as in Ghioroclystis, stalk of 1st sub- 
costals arising very near base, anastomosis of 1st subcostal with costal short, 5th subcostal parallel with stalk 
of 2nd—3rd and with 1st radial; 2nd subcostal of hindwing not stalked. Almost certainly a further section 
of Ch.loroclystis\ one of the chief distinctions which Joanxis l)8lieved to have noticed (1st subcostal not ana¬ 
stomosing) was an error of observation. Only one species. 
C. multicolor J. Joan. (12 c). Unmistakable in the sha])e of the forewing. Variable as regards the 
presence or absence of the green element in the wings. Mauritius. 
25. Genus: Cwyiiiiioscelis 
An offshoot of ChlorocJystis, not (or not directly) of Eupiihecia, as stated in Vol. 4, p. 298, only defini¬ 
tely distinguishable by the loss, total or almost total, of the proximal spurs of the hindtibia. The palpus 
shows some different forms, the build is sometimes more slender, with wings narrower, the green colouring 
not ju’evalent, the 1st subcostal of the forewing much more usually merely anastomosing with the costal than 
running into it, extreme specialisations of the EG uiucli rarer; but none of these distinctions is essential. The 
genus is chiefly Indo-Australian, but straggles into Eiirope and Africa. The supposed North American represen¬ 
tatives have been assigned a separate genus, Nasusina. Africa certainly produces several species, but in some 
cases they have only lieen taken singly and in poor condition, so that it would be worse than useless to mul¬ 
tiply descriptions; even of those which have already been described, some are still very ill-known. 
G. tenera Warr. (12 c). A tiny species (9—14 mm), in tone and markings somewhat recalling the very 
weakest-marked forms of pvmilata Him. (Vol. 4, p. 298), perhaps relatively somewhat narrower-winged. 
It may be briefly descrilied as reddish grey with broad white lines (no fuscous shades). Described from 
Ogruga, River Niger; reaches Senegal. I have also seen it from Kenya Colony (Beira, bred from maize), S. Rho¬ 
desia and Transvaal; ])resnmably an "insect of cultivation". 
G. birivulata Warr. (12 c). Size of the largest tenera or scarcely larger, wings broader and much dar¬ 
ker; hindwing with a small terminal concavity, so as to recall a small dark Chloroclysfis grisea. Described 
from the island of Sao Thome; I think known also from Principe. 
G. crassata Warr. (12 c). Less small (16-—19 mm), relatively longer-winged, the hindwing regidarly 
rounded. Characterized by the very strong outward bend of the postmedian of the forewing, culminating in 
a more or less sharp angle at the 3rd radial. The type 9 is rather clear l)rowansh, wdth the ante- and postmedian 
sharply defined as narrow’ dark bands; the rest of the original series (Sao Thome) much less variegated. A 
few’ poor specdmens from Ivory Coast, Cold Coast and Nigeria probably belong wdth it. — On Madagascar, 
about Diego Suarez, it reappears in abundance in a variable race wdiich I name; varians stihsp. nov., wdth 
the forewing slightly more produced anteriorly, nearly ahvays strongly marked, the postmedian showing the 
band-like development of crassata type, l^ut w’ith more clouding in the distal area. In some examples the 
ante- as w’ell as the postmedian show’s a sharp angulation, but as these may possibly represent a different 
species I have chosen as type a $ in which it has just the same form as in c. crassata. — ■ ab. loc. tripartita 
nov. (12 d) is a pretty form, with the proximal and distal areas of the forewdng heavily suffused w ith fuscoirs; 
fomided on 8 $$ from Diego Suarez w’hich, together with the type series, belong to the Tring Museum. 
G. olsoufieffae sp. n. Considerably larger than crassata (22 mm), palpus with terminal joint rather 
sharply pointed, abdomen (E) considerably elongate, approaching that of the acittipe7inis (lie) group, Avings
