RHOPALOCAMPTA. By Dr. C. Aurivillius.

Rh. necho Plotz (75 h) is distinguished by the almost monotonously light greyish-brown upper surface imho. 
of both wings. In all the specimens before me the hindwing beneath lacks the two distal black dots in the 
area 1 c, which occur in Plotz’s description and in his figure we have copied here. That form may be called 
ab. tripunctata ab. nov. Sierra Leone to Gabun. tri punctata. 
Rh. sejuncta Mob. <£? Vuill. (75 f) is easily discernible by the marks stated in the review. East Africa : * rjxnda. 
Usagara. 
Rh. keithloa Wallengr. (75 g). Both wings beneath of a monotonous blackish-grey ground-colour, keithloa. 
Hindwing beneath with an oblong orange spot at the anal angle in area 1 b and with similarly coloured fringes 
from the proximal margin to the centre of the distal margin. Cape Colony to Delagoa Bay. — The larva is 
very much like that of Rh. forestan. Head cordiform orange-red with two horizontal transverse rows of purple 
brown dots, 4 in the upper row and 5 in the lower. Body with a yellow ground-colour; first joint, however, 
uni-coloured brown; the others in front with a broad purple brown transverse band and behind it with one 
(joints 2 and 3) or two (the others) similar transverse lines; lateral line on the joints 2 to 12 light red; thoracal 
feet light red with yellow claws. Papa yellow or reddish and covered with a chalk-coloured irroration. — 
tancred Plotz (75 g) only differs by the fringes of the hindwing being orange-red as far as the apex of the wing, tancrcd. 
and it is probably only an aberration of keithloa. Natal. 
Rh. bocagei Em. Slip, is said* to resemble keithloa on the under surface. Forewing beneath quite bocagei. 
brown with a faint bluish lustre, hindwing also beneath brown, but with a somewhat triangular, bright orange-red 
spot enclosing three large black spots. The first spot in area 1 c, the second in 2, and the third in 4; a small 
orange spot outside of the larger spot, and a broad orange stripe at the end. It only occurs in the Island 
of St. Thomas and belongs to the highly interesting, endemic forms of that island. 
2. Subfamily: Pamphilinae. 
To this subfamily all the genera are reckoned, in which the vein 5 of the forewing is a little posteriorly 
bent at its beginning and distinctly rises nearer at vein 4 than at 6. As I am positive that comma L. must 
be regarded as the type of the genus Pamphila F . *) and not palaemon, I have denominated this subfamily 
as Pamphilinae. 
I. Third palpal joint noduliform or coniform, generally not or only slighthly projecting beyond the hairing 
of the second joint, rarely distinctly haired or scaled. 
A. Antennae long and extending far beyond the centre of the forewing; the frequently reverted, narrowed 
apical part of the antennae is also long and much longer than the largest transverse section of the club. 
a. Palpi porrect; third palpal joint large and thick, coniform. 6. Gamia. 
(3. Palpi bent up, appressecl to the frons; third joint much smaller, not porrect. 
*. Veins 3 and 4 of the forewing at their rise just as far or farther separated than the veins 4 and 5. 
f. Margin of forewing straight. Wings above uni-coloured or only at the costal margin of the 
forewing somewhat lighter, without any hyaline spots. 1 . Acallopistes. 
ff. Margin of forewing more or less bent. Wings very rarely above uni-coloured. 
§. Head scaled quite yellowish-red. Wings above partly with a bluish or greenish reflection 
without any hyaline spots. 7. Pteroteinon. 
§§. Head not conspicuously coloured. Wings above without a metallic reflection, but 
forewing generally with light spots. 
o. Vein 2 of forewing rises in or before the centre of the discal cell. 
-. Hindwing above uni-coloured blackish-brown, without spots or rarely spotted 
white. 8. Caenides. 
—. Hind wing above for the greatest part yellow or yellowish-brown or with a 
yellow discal band. 
1. Hindwing beneath with some white spots encircled with black. Last palpal 
joint short, coniform. —- <$ hindwing above in areas 1 c, 2, and in the discal 
cell with a distinctly defined, oval, brown or blackish mealy spot. 
23. Osmodes. 
*) In the description of the genus Pamphila, Fabricius says: ,,Club with a small recurved hook , which applies to 
comma, but not to ,,paniscus“. A species to which the description does not apply, cannot be regarded to be the typical one.
