60 DISCOMIOSIiS; TRICENTROSCELIS; ANTITRYGODES. By L. B. Pkout. 
P. similinotata Prout ( Sei ). Extremely like (Zig'ammafa but with the pectinations rudimentary, the lower 
part of the face less clear white (more fuscous-mixed); the cell-mark broader, intermediate in shape towards 
that of meroearia. Upper Congo. 
P. rieumanni Prout (8 b). Structure and shape nearly as in similinotata, the pectinations scarcely so 
short. Forewing with cell-mark reverting more nearly to the shape of that of aegretta, without anterior 
prolongation; lines fine and weak, the postmedian almost obsolete anteriorly. S. W. Abyssinia: Djiren, Djim- 
nia; tyj^e in Mus. Tring. 
18. Genus: l>iiseoiiiioisis Prout. 
Antenna of d with 2 pairs of fascicles to each joint, the stronger pair arising from short slender 
pectinations. Hindtiliia of 8 with strong hair-pencil and sheath (except in arciocentra), the spurring irregular; 
of $ with a pair of terminal spurs and one or l)oth of the proximal. Eorewing with areole double, the 2nd sub-, 
costal arising from the cell, 2nd radial from scarcely before the middle of the discocellulars. Hindwing with 
2nd sid^costal connate or very shortly stalked with 1st radial. A small African genus, differing from Somatina 
in the point of origin of the 2nd subcostal of the forewing, generally in the structure of the hindleg and of 
the c? antenna, also in the facies. 
D. arciocentra Prout (6 g). Hindtibia of d with proximal and 2 terminal spurs; of $ with 4 spurs. 
Antennal pectinations of d rudimentary, the fascicles strong. Less blackish and more strongly marked than 
crescentifera, for which I at first mistook it. Zululand (type), S. Rhodesia, Natal and Cape Colony. 
D. crescentifera Warr. (5 1), founded on a d from Barotse, has since been found in Ugogo and 
Rhodesia. The darkest Discotniosis. Hindtibia of d with strong pencils and sheath, the terminal spurs rudi¬ 
mentary, the proximal wanting; that of the $ with 3 spurs. 
D. anfractiiinea Prout (6g). Similarly marked to arciocentra, recognizable by its extremely zigzag 
lines; the white s]rot in front of (or suri'ounding) the cell-dot of the hindwing somewhat recalls that of Sco- 
puJa sagittilinea Warr. (6 1). Structure closely as in crescentifera (51), of which it may possibly prove a much 
paler race, though the hindtibial spurs of the d seem better developed. Kenya Colony. 
D. synnephes Prout (6 g), also from Kenya Colony, is more glossy than the other species, with a 
slightly sandy tone, a rather broad browir median shade on the forewing (sometimes strong, sometimes faint) 
and very small but generally conspicuous black cell-dots. Hindtibia of both sexes with 3 spurs. Kenya Co¬ 
lony and (a small race?) E. Abyssinia. 
19. Genus: Triceiitroscelis Prout. 
A development of Discomiosis, only ditfering materially in the strongly protuberant face, d unknown. 
Hindtibia of $ with one proximal and two terminal spurs. Only the type species is known. 
T. protrusifrons Prout (6 g) recalls a small D. arciocentra or anfractiiinea, though the angulatioirs of 
the lines are less extreme than in the latter. Founded on a single $ from British Somaliland; a few exam¬ 
ples have since been received from Gurra and from Kenya Colony. 
20. Genus: Aiititrygocles Warr. 
This genus, named from its remarkable superficial resemblance to the Trygodes of South America — 
a resemblance presumably indiiced by a similar protective habit — is evidently another development of 
Somatina, with most of the characters (single areole, etc.) of Problepsis but with more or less dentate termen 
of the hindwing; the areole, moreover, is sometimes lost through non-anastomosis of the 1st sid>costal of the 
forewing. Antenna of d with fascicles of long cilia, which occasionally arise from rudimeihary pectinations. 
Hindtibia of d strongly tufted, without spurs, hindtarsiis shoi't; of $ with all spurs. Chiefly Indo-Austra- 
lian, but includes at least 3 African species. 
A. dysmorpha Prout (51). Antenna of d with the fascicles arising from triangular teeth. Wing-shape 
more extreme than in the other Afiican species, the green median spots of the forewing moi’e confluent into 
a single, irregular band. N. Nigeria (the ty|^e) and Gold Coast. 
A. dentilinea Warr. (6 h). Near the Indian cuneilinea Walk, but with a larger cluster of green spots. 
Postmedian line of both wings beneath as direct as in that species, above — at least in the typical form — 
with a veiy pronoiinced outward angulation between the medians. Antennal fascicles of the d sessile. Sierra 
Leone (type). Ivory Coast, Nigeria, ?Gaboon, ?Madagascar and the Comoro Islands.
