Port Natal, in wliicli 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 ISTatal, the adjacent 
Coast country, and Delagoa Bay, but also occurs near Grahamstown. 
It is (except, perhaps, in size) the farthest removed from the ordinary 
Merope $. 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. 
Cenea (typical) and Trophoniiis were taken by me in the same spots at 
Knysna and Plettenberg Bay respectively, and I have since received 
the Ripjpocoo7i-like form from the former locality. Mr. Weale has 
bred Cenea (variety), TropJwnius, and a variation closer to Hippocoon 
than to Cenea, from larvae 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 hg. 2 of the second plate 
accompanying my paper in the Linnean Society s Transactions already 
referred to), all of which were taken at Highlands, near Grahamstown. 
In KafFraria Proper, as well as near D'Urban, ISFatal, Colonel 
Bowker has met with Cenea (var.), Trophonius, and the Hippocoon-likQ 
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 ISTew- 
digate about Forest Hall, in the Zitzikamma Porest, 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 Cenea 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 S , 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 rest 
rather small spots. 
An indication of aberration in the same direction is afforded by two other S 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., 1873, p. xxii., I have recorded, in connection with other in- 
stances of aberrant neuration, the case of a Kaffrarian S Cenea, in which the subcostal 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.
