NYMPH ALIN^. 277 



yields only three other species, but these are peculiar to it, viz., B. 

 Salmacis (Drury), reputed (but I believe erroneously) to have occurred 

 in South Africa ; ^ D. Monteironis^ ButL, from Old Calabar and Angola, 

 allied to Salmacis ; and the very distinct D. Dexithea, Hewits., a native 

 of Madasjascar. 



An even more striking case of mimicry than that of Danais Chrysip- 

 pus by Diadema 3Iisippus $ occurs in this genus, and has been well 

 described by Mr. Wallace {loc. cit., p. 287). It is that of the Indo- 

 Malayan D. anomala, Wall., where, in reversal of the rule among 

 butterflies, the male is dull-brown, while the female is glossed with rich 

 purplish-blue, in simulation of the protected and abundant Euplcea 

 Midamiis (Linn.) 



In Diadema, the head, the prothorax, and the sides and under part 

 of the mass of the thorax are marked with conspicuous white spots.

$ Black, with wJdle, violet-shot, large spots. Fore-iving : just beyond 

 extremity of discoidal cell, a transverse, rather large, elongate, sub- 

 ovate, obliquely-lying, white marking, shot with blue-violet (forming 

 in certain lights a lustrous circle on the black ground-colour around 

 the white), crossed by four nervules, and extending from near costa to 

 below second median nervule ; a similar, much smaller spot, crossed by 

 two nervules, close to apex. Hind-wing : a large, central, circular, 

 white marking, violet-ringed like those in fore- wing ; two or three 

 small, indistinct, thin, bluish lunules, close to anal angle. Fringes of 

 both wings very short, black, varied with white in indentations of 



^ I included this very fine species, which expands 4^ inches, in Ehopalocera Africce 

 Austfalis (i. p. 151), on the strength of its being included by Boisduval as among Delegor- 

 gue's captures at " Port Natal ; " but as no other Natalian or South-African example has 

 ever been forthcoming, it is probable that some mistake occurred, and I have withdrawn the 

 species from this work.
