PRECIS. By Dr. C. Atjrivillitts. 
rhadama. P. rhadama Bdv. (52 c). Both wings blue above, with 4 transverse lines in the cell of the forewing, 
the veins, two lines before the distal margin, the costal margin of the hindwing and discal transverse spots in 
cellules 1 a—6 of the forewing black or blackish. In the $ the black markings are more strongly developed 
than in the G and the costal margin of the hindwing is dark brown as far as vein 5; the forewing has 3 
or 4 white dots before the apex and in the $ in addition 4,white discal spots in cellules 4—6 and 9 and a row 
of whitish lunules before the distal margin. Beneath the wings are sometimes white with a mixture of grey 
and brown, with narrow, nearly straight white median band on the hindwing and distinct eye-spots, sometimes 
arida. almost uniform grey or grey-brown with indistinct eye-spots (= f. arida form. nov. ; the dry-season form). Larva 
black with short black spines, yellowish white dorsal line, brown lateral line bordered beneath with white, and 
red-yellow collar; it lives on Acanthaceae of the genera Justicia and Barleria. Coast of Mozambique, Comoros, 
Madagascar, Bourbon, Mauritius and Rodriguez. 
Second Group. 
The forms belonging here may be called the dark species of Precis. To the characters mentioned in the synopsis may 
be added that the eye-spots are small and of almost uniform size, occasionally incompletely developed; on the hindwing they 
usually form an almost continuous transverse row between veins lb and 7 and on the forewing they are distinct at least in 
cellules 1 b and 2 or form here also a complete row. 
P. chorimene is of a dark yellow-brown ground-colour above, with yellowish-ringed eye-spots; the fore- 
wing has no white markings or at most a white dot in cellule 7; the outer of the dark median lines projects 
strongly distad at veins 4 and 5, is incurved between 4 and 2 and distally bordered by yellowish spots; the under 
surface is violet-grey with dark red-brown markings and a median line, quite straight on the hindwing. 
chorimene. — chorimene Guer. (52 b). Distal margin of the wings moderately strongly angled; under surface with distinct 
eye-spots and sharp markings; hindwing at the costal margin with 1 or 2 light yellow spots proximally 
orthosia. to the median line. .Senegal to the Congo and Abyssinia, ab. orthosia King only differs in the absence of 
angulata. the light spots at the costal margin of the hindwing beneath. Among the type-form. — f. angulata form. nov. 
I give this name to a pronounced dry-season form, which is distinguished by having the distal margin of the 
forewing much more produced at vein G, by the darker upper surface and the more uniform and weakly marbled 
under surface with the eye-spots quite indistinct. Abyssinia. 
P. stygia differs from chorimene in having the ground-colour of the upper surface darker, especially 
in the <$, and the outer median line of the forewing nearly straight and distally bounded by the dark ground- 
stygia. colour. — stygia Auriv. (52 b). Distal margin of both wings undulate; the hindwing distinctly produced at 
the extremity of vein 5; the under surface broadly suffused with violet-grey at the distal margin. Ivory Coast 
gregorii. to Angola. — gregorii Btlr. seems to be the East African form and has the margins almost entire, the hindwing 
only feebly angled at vein 5; the under surface is more uniform grey and the hindwing has usually at the costal 
margin a yellow spot in cellule 7. Ruwenzori, Uganda and Brit. East Africa. 
natalica. P. natalica Fldr. (52 c) may be at once known by having on the forewing three rather large white 
discal spots in cellules 4—6 and a white subapical dot in cellule 7; the markings are otherwise the same as in 
the other species, the interspaces between the black transverse lines of the cell and the median lines are, however, 
often filled in with red-brown and the eye-spots have red-brown rings; under surface sometimes more uniform 
with blurred markings and indistinct eye-spots, sometimes with sharp markings and distinct eye-spots. Angola 
to Natal and British East Africa. Said to occur also on Madagascar. 
gondoii. P. goudoti Bdv. (52 b) exactly agrees with the other species in markings, but is smaller, with the hind¬ 
wing more elongated at the anal angle and a complete transverse row of white-pupilled eye-spots on the forewing. 
Madagascar. 
Third Group. 
The forms of this group are distinguished by the undulate or dentate distal margin of the hindwing. It is worthy 
of note that the angle of the hindwing, when present at all, is placed at the extremity of vein 5, and not, as in the following 
group, at vein 4. 
P. terea is black-brown above with a common yellow median band, extending from vein 9 of the fore¬ 
wing to the'inner margin of the hindwing and slightly curved on the forewing; the hindwing has just distally 
to the median band a transverse row of eye-spots and the forewing at the apex 2—4 white subapical dots; 
terea. the ground-colour of the under surface is light yellow. — terea Drury (51 f) is the West African race and has 
the yellow median band 5—8mm. in breadth and divided by a fine dark line; the under surface is light yellow 
with fine brown transverse lines and grey nebulous spots in the distal part. Sierra Leone to Angola and Uganda. 
fumata. — fumata Rothsch. & Jord. is a transitional form to elgiva, the interspace between the dark basal part and 
the dark median line being more or less filled up with dark. Occurs on the borders-of-Angola and in Somaliland. 
elgiva. — elgiva Hew. (51 f) has the yellow median band only 2—5 mm. in breadth and not divided; the under surface
