Explanation of Plate XXVI. 



Mimicry of the Danaine butterfly, Amauris niavius dominicanns, 

 by a Papilio and two Nymphalingi in the Coast District of British 

 East Africa. Another Nymphaline, Enxanthe wakefieldl, ? , with a 

 pattern nearer to Amauris ochlea and shown on the same plate with 

 it (Plate XXVII, fig. 2), is during life an outlying member of this 

 combination. The figures were prepared from the best of these 1906 

 specimens available, regardless of exact locality and date. Some of 

 the time and space relationships of the combination are shown on 

 p. 496. The figured specimens are in the Hope Department, 

 Oxford University Museum. 



All the figures are | of the natural size. 

 Fig. 1. Amauris niavius, sub-sp. fJominicanns, 9 : Rabai, about 

 700 ft., 14 miles N.W. of Mombasa : September 15, 1906. 

 The white markings are seen to be far more sharply 

 defined than those of any of the mimics except the out- 

 lying Euxanthe loakefieldi, ? (Plate XXVII, fig. 2). 

 Fig. 2. Papilio dardamts, sub-sp. tibullns,^i. hippocoon: captured 

 November 3, 1906, at the same locality as the model 

 shown in Fig. 1. The subraarginal white spots of the 

 hind-wing detract from the mimetic likeness, but are to 

 some extent resembled by the female of Euxanthe wake- 

 fieldl (PMeXXYII, dg. 2). 

 Fig. 3. Hypolimnas (Euralia) usamhara : captured at the same 

 place and time as the model shown in Fig. 1. This rarest 

 member of the combination lacks the important element 

 of the pattern contributed by the spot in the fore-wing 

 cell. The fulvous patch at the anal angle of the hind- 

 wing barely visible in the figure, together with the much 

 greater development of this colour on the under surface, 

 is probably inconspicuous during flight (see p. 497). 

 Fig. 4. Hypolimnas {Enrulia) wnhlbergi : Mangea, about 500 ft., 

 about 75 miles N. of Mombasa : July 19, 1906. Strong 

 secondary resemblances are evident between this and 

 the Papilio mimic shown in Fig. 2. Thus the appearance 

 of the inter-nervular rays of the hind- wing, the outline of 

 the chief white patch, and the character of its contour 

 where the black ground colour deepens gradually, are 

 very similar in both Papilio and Nymphaline (see Trans. 

 Ent. Soc. Loud., 1902, p. 486, foot-note).
