is unknown to me and is only described as being allied to terea, but the orange-yellow band abbreviated and only 
indicated by a more or less indistinct streak proximally to the dark brown median line; fore wing as strongly 
falcate as in the dry-season form of terea. British East Africa to the Arusa-Galla country. Perhaps the same 
form as furnata ? 
^P. andremiaja differs from all the other species in the shape of the hind wing, which has a long pointed 
tail at the anal angle and in addition a lobe or short tail at the end of vein 5 and is further acutely angled 
at the extremities of all the veins. Both wings above with common light median band, which in the J is nar¬ 
rower, 2—6 mm. in breadth, and white with bluish margins, but in the $6—8 mm. and entirely or in part red- 
yellow to yellow-brown. Madagascar, andremiaja Bdv. (50f; also as musa) is the rainy-season form and has the an/lremiaja.

and has a more clouded under surface without white spots and without sharply defined median band; in the

P. limnoria. The white-pupilled eye-spots of the upper surface are usually all present and are placed 
beyond the light, often very narrow or even indistinct median band; the cell of the forewing with 2 or 3 red- 
yellow, black-edged transverse streaks; at the distal margin of both wings a row of yellow or red-yellow spots. 
The median band is whitish or light yellow beneath and in the basal part there are on the fore wing 3 and on 
the hindwing 2 white or yellowish transverse lines. — limnoria King is smaller and darker than the other forms, limnoria.

P. guruana Bog. is unknown to me and is described as follows: “Wings black-brown, beyond the middle guruana. 
with a common reddish transverse band, which at the costal margin of the forewing is narrow and curved 
based; it is basally bordered by a row of black dots and before the apex accompanied by three white dots; 
the hindwing with a row of fine black dots in the transverse band and the fringes chequered; wings beneath 
dark brown, chequered with grey in the middle; the transverse band reddish, proximally whitish, distal part 
grey with a row of dots as above”. Butler asserts that guruana is an extreme rainy-season form of limnoria ; 
but according to the description it seems rather to be a form of archesia, since in limnoria the median band of 
the forewing is nearly straight, while in archesia it is distinctly curved basewards at the costal margin. 
P. archesia. The black submarginal dots on the hindwing and in cellules 1 b—3 of the forewing are 
placed in the light median band; the latter is bifurcate at the costal margin of the forewing, with the proxi¬ 
mal branch distinctly curved basad; the submarginal dots of the hindwing usually without white centres; 
those of the forewing on the contrary normally white-pupilled, or entirely white (in cellules 4—6). The fringes 
of both wings white-spotted. Through numerous experiments made by G. A. K. Marshall and others it has 
been proved that the following forms, formerly quoted as separate species, are only seasonal forms of archesia. 
Thus transitions between the extreme forms are not rare. The species occurs in South and East Africa as far as 
Angola and the Victoria Nyanza. The larva is black sprinkled with small white dots and lives on a species of 
Plectranthus. —- archesia Cr. (52 a) is the dry-season form; the median band of the upper surface is red-brown archesia. 
and moderately broad on the hindwing and in cellules 1 a—3 of the forewing, the proximal branch is blue or 
whitish and the distal narrow and brown or absent; the cell of the forewing is adorned with 2 or 3 bluish 
transverse streaks; the under surface is grey or brown and marbled with darker spots and lines; the median band 
is very narrow, a mere line, whitish with black edges, f. staudingeri Dew. is an intermediate form, agreeing staudingeri 
with archesia above but beneath almost without the spots and with the ground-colour dark brown in the basal 
part, grey clistally. f. semitypica Auriv. is a second transitional form, more nearly approaching the rainy-season semitypica. 
form; the median band on the upperside is lighter and broader than in archesia, but darker and usually also 
narrower than in pelasgis and red-yellow to the costal margin of the forewing; beneath it is broader than in 
archesia, 2—5 mm., but distally blurred, not sharply defined as in pelasgis-, the cell of the forewing above with 
blue transverse streaks; the basal part of the under surface is unicolorous black-brown without distinct spots, 
i. chapunga Hew. is also a transitional form, agreeing with pelasgis beneath, but distinguished above by having chapunga.
