DAN AID A. By Dr. C. Aurivillius. 
it is distinguished by having the white subapical spot in cellule 4 of the forewing smaller, more rounded, 
and more or less completely separated from spot 5; also the other subapical spots are shorter and more 
chrysipellus. rounded than in the eastern local form; the hindwing has a brown-yellow ground-colour, ab. chrysipellus 
Strand is an extreme form, in which the spot in cellule 4 of the forewing is circular and is separated from 
alcippus. the spot in cellule 5 as well as from that in cellule 2. Cameroons. — alcippus Cr. (vol. I, pi. 28 a) only 
differs from the type-form in the ground-colour of the hindwing, which is more or less extended white. 
Occurs among the typical form, but is very common in the West African forest region, where it almost 
orientis. entirely supersedes the type-form. orientis Auriv. (vol. I, pi. 28 a as chrysippus ) has a much broader white 
subapical band on the forewing with the spot in cellule 4 elongate, quadrate and touching the spot in 
cellule 5 for a long distance; the hindwing without white; it occurs in South and East Africa among typical 
chrysippus as a transitional form, but on the East African islands is almost the only form, being the commonest 
alcippoides. one in South Asia. ab. alcippoides Moore has the hindwing more or less white, but otherwise agrees with 
orientis and occurs together with it. 
dorippus. D. dorippus King (vol. I, pi. 28 b) is similar to the preceding species, but is at once distinguishable 
in that the apex of the forewing is brown-yellow and only margined with black and has no white subapical 
infumata. band; the ground-colour is not darkened at the base, and the hindwing not white, ab. infumata Auriv. 
(vol. I, pi. 28b, as klugii ) only differs in having the brown ground-colour of both wings darkened at the base. 
albinus. ab. albinus Lanz. (vol. I, pi. 28 b) has the middle of the hindwing more or less broadly white. As var. 
iransiens. transiens Suffert describes a form in which a white subapical band is more or less distinct on the underside 
of the forewing. The species occurs in South and East Africa, in Arabia, on Sokotra and the Comoro 
Islands; but is entirely absent in West Africa; it is often regarded as only a form of chrysippus, but of this 
there is no sufficient evidence. — D. chrysippus and dorippus serve in Africa as models for a whole series 
of mimetic species; the former for Hypolimnas misippus-% with ab. alcippoides; Pseudacraea poggei; Acraea 
encedon with ab. alcippina; Mimacraea marshalli; Telipna sanguinea; Cooksonia trimeni; Aletis helcita; 
Euphaedra ru,spina; Papilio dardanus ?-f. trophonius, and many others; the latter for Hypolimnas misippus ?-f. 
inaria and dorippoides; Acraea encedon ah. dear a; Mimacraea. doliertyi; Acraea johnstoni ab. fulvescens and 
Papilio dardanus ?-f. dorippoides. 
Limniace Group. 
The middle discocellular vein of the hindwing is only slightly curved or quite straight. The cf has in cellule lc 
of the hindwing a large scale-pouch, beneath projecting as a sack. The wings are ornamented with numerous light spots 
on a dark ground; the spots at the base are elongate, but in and behind the middle rounded and arranged in 2—4 irregular 
curved rows. — The larva only possesses 2 pairs of fleshy filaments, which are placed on segments 2 and 11 (= Tirumala Moore). 
petiverana. D. petiverana Dhl. & Hew. (23 a), has a blackish ground-colour and light green markings: 
the forewing has only a longitudinal streak at the base in the cell, but the hindwing deeply cleft basal 
streaks in cellules 1 b, 1 c and the cell; the cell of the forewing has a transverse spot behind the middle; 
the forewing has three discal spots in cellules lb—3 and 2 each in cellules 4—6; the submarginal spots 
are small and punctiform, the hindwing has two larger proximal discal spots (in cellules 4 and 5), a complete 
curved row of distal discal spots and small submarginal dots; the under surface is lighter grey-brown than 
the upper and only blackish in the middle of the forewing. Common everywhere in the tropical districts of 
Africa; wanting in South Africa and on the East African islands. 
Formosa Group. 
This group, peculiar to the Ethiopian Region, is very nearly allied to the preceding and only differs in having no 
spots on the basal third of the forewing and the basal spots of the hindwing large and undivided. The spots on the wings 
are arranged practically as in the Limniace Group, but are less numerous. — Melinda Moore (= Elsa Honr.). 
morgeni. D. morgeni Honr. (23 a) has the forewing blackish, somewhat brownish at the base, and the hindwing 
black-grey; the forewing has a white spot behind the middle of the cell, a large discal spot in cellule 2, 2 
white subapical spots in 5 and 6 and midway between these latter a transverse row of 4 white spots; the 
hindwing has 3 large white basal spots and in addition only 4 submarginal spots in cellules 3—6; the under 
surface coloured and marked as the upper. Cameroons. 
mercedonia. D. mercedotiia Karsch (23 b). The unspotted basal part of the forewing and the hindwing to beyond 
the middle are dark chestnut-brown, the other parts blackish; the light spots are whitish and formed almost 
as in morgeni; but the hindwing has behind the middle a row of spots distinct also in cellules 1 a—3 and 
submarginal dots. German East Africa, Uganda and Toro. — Papilio mimeticus may be mentioned as a mimic.
