Port Natal, in which all the black markings are strongly developed, 

 especially the discal band of the hind-wings, which in some examples 

 is quite unbroken. This form is most prevalent in Natal, the adjacent 

 Coast country, and Delagoa Bay, but also occurs near Grahamstown. 

 It is (except, perhaps, in size) the farthest removed from the ordinary 

 Mcropc $. I know of no locality in South Africa in which the ^ s 

 are constant to any particular pattern ; but, amid all their variation, I 

 have noticed no example that approaches the West-African $ in the 

 strongly-marked inter- nervular rays of the under side, except where 

 (in some of those in which the black markings are most developed) 

 the rays cross the discal band in the hind-wings. 



Looking to the Southern ^ s, it is equally observable that the 

 several well-defined forms are not restricted to particular localities. 

 Ccnca (typical) and Trophonins were taken by me in the same spots at 

 Knysna and I'lettenberg Bay respectively, and I have since received 

 the Hi]}pocoon-\\\^Q form from the former locality. Mr. Weale has 

 bred Ccnca (variety), Trophonius, and a variation closer to Hippocoon 

 than to Ccnca, from larvse taken in one spot near King William's 

 Town ; and Mrs. Barber has sent me the three forms, as well as a 

 variation (very near that delineated on fig. 2 of the second plate 

 accompanying my paper in the Linncan Society's Transactions already 

 referred to), all of which were taken at Highlands, near Grahamstown. 



In Kaffraria Proper, as well as near D'Urban, Natal, Colonel 

 Bowker has met with Ccnca (var.), Trophonins, and the Hipp)ocoon-\\kQ 

 form ; and I have recorded above the singular linking variations found 

 by Mrs. Monteiro at Delagoa Bay. 



In a most interesting series lately (1887) collected by Miss New- 

 dio'ate about Forest Hall, in the Zitzikamma Forest, Plettenberg Bay, 

 there are ten ^ s presenting similar variations to those of the Grahams- 

 town examples above mentioned, the hind-wing band especially show- 

 ing every gradation from three separate spots to complete continuity ; -^ 

 twelve ordinary $ s of the typical Ccnca form, but varying a good deal 

 in the size of the spots and of the hind-wing patch ; one $ of the 

 Second Form, but with an exceedingly narrow subapical white bar in 

 the fore-wings ; and two $ s of the Third Form ( = typical Trophonius). 



^ One <J , with the hind-wing band continuous throughout, has in the dark border of the 

 fore-wings not only a larger than ordinary subapical spot, but a series of six diffused pale 

 sulphur-yellow markings, of which the first (subcostal) is a conspicuous longitudinal ray, 

 the second (interrupted by black-ringed subapical spot) and third shorter rays, and the I'est 

 rather small spots. 



An indication of aberration in the same direction is afforded by two other i s (one from 

 the George District of the Cape, and the other from Pinetown in Natal), which alike exhibit 

 two very small pale sulphur-yellow spots in the fore- wing border between first radial and 

 third median nervules. 



In Proc. Ent. Soc. Lond., 1S73, p. xxii., I have recorded, in connection with other in- 

 stances of aberrant neuration, the case of a Kaffrarian S Ccnca, in which the svibcostal ner- 

 vules of both hind-wings are united by a transverse additional nervule, so that a completely 

 closed second cell is formed immediately adjoining the ordinary discoidal cell, and extending 

 beyond it.
