PIERIN.^. 147 
This beautiful " sport " resulted from a pupa forwarded in August 
1887 from D'Urban, Natal, by Colonel Bowker. The pupa was attached 
to the base of the lanceolate leaf of a small tree ; " it very closely 
resembled that of T. Antevijjpe, (Boisd.), received at the same time 
(see above, p. 137), but was of a deeper colour, and had a pale apical 
I space on the wing-covers. 
Mr. Aurivillius, of the State Museum in Stockholm, kindly obtained 
for me a carefully executed coloured figure of Wallengren's type ($) of 
Frocne ; it agrees very closely with those specimens from Natal and 
Zululand in which the inner black border of the apical patch is most 
developed. 
The united sexes have twice been taken by Colonel Bowker, viz., 
at D'Urban, Natal, on 15th August 1878, and at Coega Eailway 
Station in the Uitenhage District of Cape Colony in October 1879. 
The ^ s of these pairs are smaller than usual, and closely alike, except 
that the D'Urban individual has a little more blackish inner-marginally 
and less on inner edge of apical patch than the Coega one ; while in 
the $ s just the reverse is the case, besides which the Coega $ has 
i the lower part of the discal ray of the hind-wings more complete. 
Small $ s appear to occur more commonly than small ^ s. I have 
received about three times as many of the former as of the latter. The 
smallest $ is from the Bashee Eiver in Kaffraria, — the smallest $ from 
Delagoa Bay. I have not found any trace of the longitudinal blackish 
bars in any of these under-sized $ s. The largest examples of both 
i sexes, and those in which the black markings — especially the inner 
border of the apical patch in the $ — are best developed, are from 
Natal, but very small ^ s have also been received from that Colony. 
The characters emphasised in my description seem to warrant our 
holding Theogoiic as distinct from its congeners. The width of the 
j apical red or orange, with the absence of black neuration crossing it, 
and (in the ^) the way in which the broad lower extremity of the 
I curved orange band meets the white field, are notable features. 
The butterfly has a wide range over Eastern South Africa, and seems 
! particularly prevalent on the Natal Coast in the winter (dry) season. I took 
the $ at I3'Urban as early as the 8th April, and at Grahamstown, Cape 
Colony, on the 5 th June.
