258 SOUTH-AFRICA^^ BUTTERFLIES. 
extremity of the cell ; (7) tlie small whitish spot in the upper part of i 
the cell, near its extremity, sometimes found in Cynorta, is wanting ; 1 
in the hind-wing, (8) the basal ochreous is darker and more rufous in 
tint, extending farther costally ; (9) the band is considerably narrower, 
its inner edge not so even, the brownish clouding of its outer border 
better defined ; (10) the inter-nervular rays are not so strongly marked; 
(11) the discal whitish spot is not found in Cynorta. It is also to be | 
noted that Ucherioides is considerably the larger of the two species. ' 
The $ s of these two very similar ^ s are surprisingly different, for 
while that sex in P. Ucherioides (as mentioned above) so closely 
mimics Ama^iris Eclieria as to be in life indistinguishable from the 
$ P. Cenea, the $ of Cynorta (described by Westwood under the name 
of Boisdnvalliamis ^) closely copies the very differently marked Planema 
Gea, (Fab.) — a well-known native of Western Africa. The feature 
common to these two $ s — by which the collector can at once distin- 
guish Eclierioides from Cenca — is the ochre-yellow black-spotted basal 
patch on the under side of the hind-wings. This character is in the 
^ s of Cynorta and Eclierioides even more developed than in the $ s, and j 
is in direct mimicry of the Planema; and its continued existence in 
the $ Eclierioides — which mimics a Danaine butterfly not possessing 
this peculiar marking — points to the inference that mimicry of the 
Plenenia group was in both these Papiliones the earlier tendency, and 
has only more recently been diverted in the direction of Amauris in 
the case of the Southern species. 
Archdeacon Kitton, of King AYilliam's Town, first brought this interesting 
Papilio to my notice, having in April 1863 forwarded a $ example captured 
by him in the Perie Bush.^ Colonel Bowker in 1865 found the butterfly 
numerously in the Sogana and Boolo Forests, near the Tsomo River in 
Kaffaria, and sent me a number of specimens of both sexes, including two 
pairs taken in copula. He noted that there were two broods in the year, one 
in November, not lasting for more than about four weeks, and the other in 
January, continuing to appear until far into March. "The s," he wrote, 
take a constant course through the forest, returning regularly by the same 
route ; while the ? s keep about the place, but fly at a lower elevation, and 
do not appear to take the rounds of the ^ s. The sexes disappeared together 
at the end of November, and did not appear again until early in January, 
when they both came out on the same day. AYhen the ^ and $ meet, they 
whirl about together among the tops of plants in the forest, and as soon as 
united, disappear down under the leaves." 
I only once chanced upon living Eclierioides, on the 8th March 1867, in 
high-lying woods at Tunjumbili, on the Tugela border of Natal. The 
were tolerably numerous, but I saw only two $ s, and at first mistook one of 
them for P. Cenea. The flight of the insects quite confirmed Colonel Bowker's 
1 A single example from Natal has a very faint trace of this spot in each fore-wing. 
2 Strong evidence of the species-identity of Cynorta and Boisduvallianus was adduced 
in 1878 by the late Mr. D. G. Rutherford, who exhibited at the June meeting of the Ento- 
mological Society of London a specimen showing on the left side the wing-markings of 
Cynorta, and on the right side those of Boisduvaliianus. 
3 This specimen reached me in a very damaged state ; and I erroneously referred it 
to P. Messalina, Stoll, and so recorded it in Ehopalocera Africce Australis, ii. p. 329.
