The characters of the last mentioned were the following, 

 vid. : — 



Fore-iving : inarJcings rich deep ochre-yellow , — the suh-ajncal 

 bar, disco-celhdar streak, and viuch narrowed, hut superiorhf 

 prolonged inner-marginal ixUch being confluent into a wide 

 discal hand very irregular in outline ; some slight fuscous 

 scaling on yellow band between 2nd and third median nervules 

 indicates the normally Avide separation between the sub-apical 

 and inner-marginal markings ; ordinary apical spot wanting ; 

 two small sub-marginal spots respectively above and below 

 2nd median nervule of the same ochre-yellow as the discal 

 band. Hind-ioing : white patch from base outward much 

 restricted, barely reaching middle and extending only just 

 beyond extremity of discoidal cell ; sub-mai'ginal spots all dull 

 ochre-yellow except the three next apex which are white. 

 Under-side : Apex of fore-wing and all outer area of hind-wing 

 of a paler brown than in the form Ilippocoon. Fore-wing : 

 ochre-yellow bar as above but rather paler, and with scarcely 

 any fuscous scaling between 2nd and 3rd median nervules ; 

 an additional sub-marginal very small ochre-yellow spot close 

 to posterior angle. Hind-ioing : restricted white patch as 

 above, but much duller. 



The second example (from Angola) of this form of the 9 

 merojoe agreed very nearly with the Uganda specimen above 

 described, only differing in the rather duller ochre-yellow^ of 

 the band in the fore-wings ; in the presence in the same wings 

 of a very small ochre-yellow apical spot, and of a similar spot 

 close to the posterior angle on tlie upper-side ; and on the under- 

 side the increase of the fuscous scaling about 2nd median 

 nervule, so as almost to interrupt the yellow discal band. 



This made the fourth pronounced known form of the $ 

 Papilio merope. The usual and generally distributed form 

 of this sex throughout Tropical Africa was that named Hippo- 

 coon, by Fabricius — an excellent mimic of Amauris niavius, L. ; 

 all the other forms appeared to be very rare, and two of them 

 — Dionysos, Doubl., and the form from Zanzibar described in 

 Mr. Trimen's Presidential Address to the Society on January 19, 

 1898 — were not direct mimics of any other butterflies, but were 

 least divergent from the non-mimetic coloration and pattern
