[The above description, although originally drawn up from 

 the specimens captured up to Nov. 13, is applicable to the 

 entire series, now carefully examined. Specimens with traces 

 of the extra black spots on the hind-wing under surface were 

 as numerous in the later captures as in the earlier. A few of 

 the later carpenteri showed interesting vestiges of the type 

 pattern towards the apex of the fore-wing.] 



A comparison between the details of the mimetic likeness 

 borne by poggei and the $ misippus to their model, and 

 between the patterns of the co-mimics themselves, was pub- 

 lished by the present writer in Trans. Ent. Soc, 1905, pp. 265-7. 

 At that time I was not aware of the critical comparison between 

 the same forms which the late Mr. Roland Trimen, F.R.S., 

 had published at a much earlier date, in Proc. Zool. Soc, 

 1891, p. 79, based on a single male from Omrora, Angola, 

 which corresponded in size " with the smaller than usual 

 I), chrysippus from the same locality." Mr. Trimen found 

 that poggci was a closer mimic than the $ misippus in three 

 features : " On the upperside of the fore-wings the much 

 narrower costal black and the absence of the apical white 

 spot, and on the upperside of the hind-wings the narrower, 

 less diffuse, inwardly more sharply dentate hind-marginal 

 black border. On the other hand, the greyish-white clouding 

 on the underside of the apex of the fore-wings and the con- 

 spicuous spotting of the abdomen are points which lessen 

 D. [P.] poggei s likeness to D. chrysippus as compared to the 

 colouring of the corresponding parts in D. misippus. These 

 two characteristics and the subbasal black spots on the under- 

 side of the hind-wings are retained generic features of Pseud- 

 acraea, quite peculiar and unmistakable. . . . The rufous- 

 ochreous ground-colour of the wings exactly accords with that 

 of Danais chrysippus, and the paler tint of the hind-wings 

 is most perfectly reproduced; while on the underside the 

 creamy ochre-yellow ground and the white neuration and black 

 border of the hind-wings (with also a general resemblance in 

 the few white-edged black spots) are precisely simulative of 

 the Danais."
