RHODOMETRA. By L. B. Prout. 
ship with Traminda, but in the absence of clear evidence we leave it next to Rliodometra, from which it 
differs chiefly in the flat face, narrow wings and long cells (see Vol. 4, p. 153). There is only one species, 
though this has been provisionally separated into 2 races. 
philaearia. Ps. panllula Swinh., from the plains of India, will be described in Vol. 12. — philaearia Brabant 
(= gayneri N. C. Rothsch.) (7 m), described from Egypt, but distribiited through the Sudan to Senegambia 
and to Kenya Colony and Kilimandjaro, is variable, perhaps not racially differentiable; $$ often more 
weakly mai’ked, but still not so weakly as in the (^(J. 
29. Geims: Itlioclometra Meijr. 
A somewhat isolated genus, obviously of African origin, although the genotype is a migrant with a 
very wide range and a similar species {antopliUarki Hhn.) inhabits the Mediterranean countries (see Vol. 4, 
p. 154); much more unaccountably, two or three species are found in South America, chiefly in Ecuador 
and Peru. On account of the anastomosis of the costal vein of the hindwing with the cell, at least as 
far as the middle, the more rigid analysts have ])laced it in the Larentiinae, but the genitalia and some 
]>oints in the forewing venation show it to belong to the Sterrhinae. Pierce (“Genit. Geom.”) associates it 
with the Cosynibia group, but the “socii”, shape of saccus and formation of the valvae seem irreconcilable 
therewith. Face ]irotuberant, tongue strong, antenna strongly pectinate, forewing with areole large, simple, 
1st discocellular present, hindwing with 2rd subcostal not or only very slightly stalked. Pattern generally 
cpiite simple, the hindwing ])lain white, or dark-grey with ill-defined whitish band. 
sacrarki. R. sacraria L. (7 m). Very variable, though most of the extreme aberrations are cpiite rare (see 
Vol. 4, p. 154). The name-type is the most usual (J form, the forewing yellow, with the oblicpie stripe 
labda. com])lete, rosy. - ab. labda Gram. (7 m) is noteworthy as being the usual $ form, the forewdng less bright, 
more straw-colour, with the line browmish, generally not c[uite I'eaching the hindmargin. Similarly coloured 
specimens, however, occur occasionally in the (^. The early stages and habits of sacraria are briefly noticed 
in Vol. 4. Linne’s type was from North Africa, but the range covers the whole of the continent, besides 
much of Europe, western Asia, the Canary Islands and St. Helena. 
lucidaria. R. lucidaria Swinh. (7 m) may perhajis be a form of phctaria without the red terminal line, the 
fringe, on the other hand, tinged with rose-colour. Perhaps the largest Rhodometra. Abyssinia, Kenya (loc. 
typ.), Tanganyika and Nyasaland. 
picctarki. R. plectaria Cue??. (8 c). “Larger than .socrarfa (34 mm). Forewing cpiite triangular, with the margins 
very straight. The oblicpie line is always mixed with black; the costa is tinted wdth rosa throughout, 
and there are further 3 or 4 unequal marks on the disc, of a dark rose-colour, ])lacecl in oblicpie series be¬ 
tween the veins. Fringe preceded by a rosy line. Hecul and palpus also tinged with rose.” Abyssinia. 
ntervenata. R. illtervenata Warr. (7 m). vSmaller than lucidaria, with increased longitudinal markings, longer and 
less oblicpie streak from apex, red terminal line and clean yellow fringe. Pos.sibly a local race of plectaria. 
Only known from the highlands of Kenya Colony. 
paiiici- R. participata Wall-. (8 1). A small species, with white cell-spot, very similar on the forewing to 
pata. antophilaria Hb. ab. subrosearia, but with the line more oblique and more slender, rather strongly dark-edged 
peculkiia. proximally, and with the white hindwing almost unmarked. — ab. peculiata Walk, is a more uniformly 
reddish aberration, the pale line weak, its proximal edging narrow and grey. Natal. Typical participata 
was described fi'om Namaqualand Init is best known in Cape Colony. 
audcondi. R. audeoudi Front (8 c). Rather larger, more variegated but without the conspicuous white cell-spot, 
the tints on the whole duller, the dark oblique streak vertiially replacing the whitish one; hindwing greyish. 
Delagoa Bay district. 
sutura. R. satura Pront (8 c) differs from all the other African species by its dark hindwing; from rosearia 
Tr. (Vol. 4, pi. 7 f) by its broader red costal border, more oblic{ue red stripe (broadening the yellow band 
beyond it posteriorly) and obsolescence of the ])ale band of the hindwing. Antennal pectinations of the 
a little less long. Delagoa Bay (type), Transvaal and Durban.
