apical portion, beyond larger stripe, shining yellow-ochreous ; 

 hind-marginal lunulesas in $ . Ilind-iving : shining yellowish- 

 ochreous ; a whitish central shade indicates position of white 

 transverse band ; blackish costal spot as on upper-side ; a 

 blackish mark at base, on costal nervure; and another, rounder, 

 blackish mark at extremity of discoidal cell, on discoidal 

 nervule ; hind-marginal border as in ^ , as well as row of white 

 dots parallel to it. 



Var. $ (D. Inaria, Cram.) — A suffusion of the reddish- 

 ground-colour covers apex, only leaving costa and hind-margin 

 blackish ; the ivhite stripes being also almost obliterated with 

 the same hue. 



Larva. — " Resembling, at first sight, that of D. Chry- 

 sippus, especially in colour and marking ; but the spinous 

 elongate organs are stifFer, less mobile, and eight in number. 

 Gregarious on Nerium.''^ 



Pupa. — " Less cylindrical (than that of Chrysippus), 

 slightly constricted, green, without gilded spots or black 

 ring." — Boisd., Faune Ent. de Mad., p. 40. 



Marshes, gardens, and open ground. 



February (m) — March (m). 



Uncoramou at Knysna and Plettenberg Bay, early in the year 1859. 

 The few specimens I took were all females, but both sexes are, I am in- 

 formed, common there in some years. The flight of those I noticed 

 resembled that of a Danais, but was swifter. Knysna is the most Southern 

 locality recorded for this haudsoine Butterfly, which is a very widely-spread 

 and common species throughout Africa and Asia. It is singular, also, that 

 the insect has likewise been captured in the New World, whither it has 

 probably been conveyed with some plants. As will be seen from the 

 synonyms given, so strikingly different are the two sexes that, until a com- 

 paratively recent period, they were ranked as not only different species, but 

 even as belonging to different Genera, by entomological authors. Bois- 

 duval stated their identity in 1833, asserting that the fact was proved by 

 their having been reared from the same Larvae. But if any one needs 

 proof, after a comparison of Bolina and Ilisippus together, the fact of a 

 hermaphrodite specimen being in the collection at the East India House 

 ought to set his doubts at rest. In connection with the strong resemblance 

 of the $ Bolina to Danais Chrysippus, Linn., it is curious that, according 

 to Boisduval, the Larva of the former species is very similar to that of the 

 latter ; and the Pupae of the two not very unlike ; both obtaining their food 

 in the larval condition from the leaves of the Oleander. It is likewise 

 worthy of remark that both Danais Chrysippus and the ? of Bolina are 

 subject to a similar suffusion of ochreous colouring, whereby the apical 

 black and white are almost obliterated.
