PIERIN.E. 147 



This beautiful " sport " resulted from a pupa forwarded in August 

 1 8 87 from D'Urban, Natal, by Colonel Bowkcr. The pupa was attached 

 to the base of the lanceolate leaf of a " small tree ; " it very closely 

 resembled that of T. Antcvippc, (Boisd.), received at the same time 

 (sec above, p. 137), but was of a deeper colour, and had a pale apical 

 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 typo ($) of 

 Procnc ; 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 Railway 

 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 

 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 River 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 

 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 Thcogonc as distinct from its congeners. The width of the 

 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 

 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 S at i)'Urban as early as the 8th April, and at Grahamstown, Cape 

 Colony, on the 5 th June.
