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. MonteironiSj Butl., from Old Calabar and Angola, 
allied to Salmacis ; and the very distinct D. Dexithea, Hewits., a native 
of Madagascar. 
An even more striking case of mimicry than that of Danais Chrysip- 
pis by Diadema Misippus ^ occurs in this genus, and has been well 
described by Mr. Wallace (loc. cit., p. 287). It is that of the Indo- 
Malayan I), 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, luith icliite, violet-shot, large spots. Fore-wing : 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-unng : 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 sJwrt, black, varied with white in indentations of 
^ I included this very fine species, wliich expands 4^ inches, in Hhopalocera Africce 
Australis (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ever been forthcoming, it is probable that some mistake occurred, and I have withdrawn the 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;
