depicts. In these examples the subapical spots of the ground-colour 
in the fore-wings are almost invariably larger than usual, and are often 
so extended as to become confluent, thus forming as large a marking 
as that shown in yellow on the under side. The extreme in this direc- 
tion is reached in an individual sent from King William's Town by 
Miss F. Bowker, where the confluent spots make a small apical patch, 
broadly bounded by black inwardly, but inferiorly completely united 
with the ground-colour, and the hind-margin bears only a narrow 
blackish edging ; while in the hind-wing the border is reduced to a 
series of quite separate ill-defined thin nervular fuscous marks with a 
small separate spot indicating the customary marked projection. 
The $ is not nearly so frequently met with as the $ ; among fifty- 
five specimens, from all parts of South Africa, now before me, only 
eight are $ s. In a pair taken in copula by Colonel Bowker in March. 
1879, the sexes do not differ much either in size or pattern, the white 
J being the broadest-bordered that I have seen, while the yellowish $ 
is of medium character in that respect. 
A dwarf very narrowly-bordered taken at D'Urban, Natal, by the 
late Mr. M. J. M'Ken, expands less than I in. 10 lin. In this example 
the subapical spots of the fore-wing border are normal, but the hind- 
wicg border has its inner edge quite even. 
Hopffer {Peters Beise n. Ifossamh., I71S., p. 363) and Oberthtir 
{Etudes d'Ent, iii. p. 21) independently note the large size and broad 
border of East -African examples (respectively from Querimba and 
Zanzibar) in comparison with those from South Africa ; it is probable 
that they both refer to specimens of the ^. 
Mrs. Barber wrote to me that the larva of this species fed on a Capparis, 
and subsequently Mr. J. P. Mansel Weale informed me that Capparis Zeyheri 
was the food-plant. Mr. Weale added that the larva much resembled that of 
Teracolus Auxo (Lucas) ] it was difficult to find, its reddish-yellow lateral stripe 
matching in tint the edge of the leaves. 
This strikingly marked Ero7iia, which has peculiarly soft rich under-side 
colouring, is widely distributed, and apparently numerous in most parts of South- 
Eastern Africa. It has been recorded from various places on the Tropical East 
Coast, and from as far north as Shoa in Abyssinia. It is swift on the wing, 
but has the family habit of pitching frequently on flowers ; and at D'Urban, 
Natal, I took a fine series at flowers of the introduced Vinca rosea during the 
month of February. These summer specimens (including a few $ s) were all 
of the larger broad-bordered description ; but two $ s which I captured, one in 
June and the other in August 1865, were small and narrow-bordered. As two 
$ s taken by Colonel Bowker (at King William's Town in May and at D'Urban 
in August respectively) are also small and narrow-bordered, I am disposed to 
think that this form of the butterfly may possibly be the winter brood, but 
hitherto there have been no correspondingly narrow-bordered 9 s recorded as 
occurring in the winter months.^ 
^ I have lately (1888) discovered in the South- African Museum a pair marked as taken 
in copula by Colonel Bowker at D'Urban on nth May 1879. These specimens are much 
smaller ( 2 in. 2 lin., 9 , 2 in. 4 lin. across fore-wings) than the pair above mentioned as 
taken in March of the same year, and both have the black border considerably narrower. 
Mr. Alfred D. Millar informs me that the butterfly is very common all the year round at
