ration, on the forewing with a white patch in end of cell, broadening thence to the submedian vein and ante¬ 
riorly irrorated with black. Kassai district, only the type known. 
C. gracilis Msclilr. {= pallida Warr., alba Drc.) (Ig, h). Likewise very variable. Ground-colour graciTif!. 
white. .Eorewing with a small buff or slightly reddish patch at base and a black costal border in addition to 
the usual white-spotted distal one. Hindwing with characteristic black wedge-shaped terminal marks between 
the veins, which are otherwise only known in variabilis ab. agis. The have usually a tawny spot in the 
border of the forewing which is obsolete in the Gold Coast, and extending through Ivory Coast to Sierra 
Leone. — variegata Prout has the basal patch of the forewing extended, reaching the costal margin, the median variegata. 
vein blackened, in the $ also an irregular, more or less extended, reddish area along the costal and thence across 
t he wing between the white and black parts. Ja River, S. Cameroons, fairly common. — landbecki ProtU is marked landhecld. 
nearly as variegata but with the variable reddish parts replaced by buff. Apparently a well-defined local race 
in the Kassai district, Belgian Congo. 
14. Genus: Paraptycliocles Warr. 
A small genus, of doubtful position, placed here on account of its mimetic association. The type 
species is said to mimic Danaida chrysippus. The G characters which (in Gen. Ins. 104, p. 101) I quoted from 
Warren are partly incorrect; the hindtibia in both sexes has 4 short spurs. Legs short. Antenna short and 
stout, in both sexes (excepting the $ of Gostimaculata) bipectinate. Cells long, forewing without areole, 1st 
subcostal free, 2nd connected by a bar with the stalk of 3rd and 4th. G hindwing with the abdominal margin 
closely folded over beneath, clothed with specialized scaling. Early stages unknown. The genus is confined 
to Tropical Africa. 
P. kedar Drc. (Ih). Eorewing white, with black apical half containing a white subapical patch, kedar. 
Hindwing with narrow black apical patch; distal border forming black triangles on the veins. Dar-es-Salaam; 
also known from Mombasa. 
P. costimaculata Prout ( 1 h) is a large species, of similar coloration to the following, but with a costal costhnacu- 
black spot at nearly one-third, the white subapical patch larger, the $ antenna not pectinate. Southern Nigeria. 
Also on the coast of Kenya Colony. Evidently much overlooked. 
P. tenuis Btlr. (Ih) Orange with narrow black borders, on the hindwing broken into vein-spots tenvis. 
posteriorly. Eorewing with a black cell-mark, succeeded by a large white subapical patch. — ab. fulva Hmps. fulva. 
has the posterior terminal spots of the hind wing wanting. —ab. (?) perfulva Prout has the subapical S230t orange, perfulva. 
not white. — Zanzibar; also from the coastal districts of East Africa from Mombasa to Dar-es-Salaam and 
perhaps Mozambique. 
15. Genus: Diptycliis Warr. 
An anomalous genus, originally assigned by Warren — on account of its colour and maculation — 
to the vicinity of Abraxas, afterwards assumed by me to be a Larentiid with some slight affinity to Ptygma- 
to'phora (Vol. 4, jd. 189) but apparently better placed near Paraptydiodes. Pali)us rather short. Antenna not 
pectinate. Hindtibia in both sexes thickening in distal half, all the spurs present, but short. Both wings with 
the cell long; forewing with the venation nearly as in Paraptychodes; hindwing with the costal vein anasto¬ 
mosing with subcostal to about the middle of the cell, the 1st radial widely separate from the 2nd sixbcostal, 
the abdominal margin of the d folded over beneath to form a jjocket containing coarse androconial scaling. 
D. geometrina Feld. (1 h). Orange, with a large black cell-sjxot on the forewing, terminal spots on both gcometrina 
wings and irregular and very variable maculation elsewhere, more cojxious on the forewing. Feeders tyjxe was 
from Natal; other localities are Zululand and Pondoland. 
D. nieraca Prout is nnicolorous orange; cell of forewing rather less long than in geometrina, distal margin meraca. 
stightly more rounded anteriorly; hindwing with the 2nd radial weaker. Fez, S. Mozambiqna, 1 ^inMus. Geneva. 
2. Subfamily: Hemitheinae. 
This subfamily, which has been discussed in its relation to the Indo-Australian fauna in Vol. 12, jxp. 3 
and 44, is also moderately well represented in the African region, but chiefly by small sjxecies. A very large 
proportion of these shows a very simple pattern — jxlain green without markings or merely with one or two
