96 SOUTH-AFKICAX BUTTERFLIES. 



trace, and in one Delagoan and two Natalian specimens are totally 

 wanting. The hind-wing band is almost always bounded inferiorly by 

 the second subcostal nervule to its termination, but the terminal por- 

 tion in one Transvaal specimen projects very slightly, and in a Natalian 

 individual considerably below the nervule. The under side of King's 

 figure is white (as in a good many South-African examples), but the 

 dark bands of the upper side are dej^icted as showing more plainly 

 through the wings than in any specimens which have come under my 

 notice. 



As regards the nervular hind-marginal sj^ots on the upper side of 

 the hind-wings, which are distinct but linear in King's figure, I find 

 that, while it is unusual for them to occur in South- African specimens, 

 they are found in those examples which more nearly approach King's t}q3e 

 (in one Delagoa Bay specimen they are rather large and conspicuous). 

 On the other hand, the terminal disco-cellular spot of the fore-wings 

 (which is wanting in King's typo and in the more heavily-banded 

 South-African examples) is most developed in specimens which bear 

 the largest hind-marginal white markings on the black band. 



The ^, besides varying in ground-colour,^ exhibits great diversity 

 in the development of the black band and of the apical hind-marginal 

 border of the fore-wings, and in the colouring and pattern of the apical 

 patch. In one from Natal, the inner-marginal band is scarcely nar- 

 rower (except for a very large white spot at the posterior angle) than 

 in the more lightly marked $ s ; while the opposite extreme is met 

 with in an example I captured near Grahamstown, where the band is 

 exceedingly narrow, and the usual black connection with the apical 

 patch is only represented by two quite separate very small blackish 

 spots." In this example the apical patch is externally broadly tinted 

 with pale dull ferruginous, and the pale enclosed spots are almost 

 obsolete, and it thus on the upper side approaches the $ of Variety A., 

 above described. Eeiche's figure of an Abyssinian $ depicts the under 

 side as inclining to argillaceous. 



In the British Museum collection I noted (October 1886) a 

 remarkably large $ labelled T. opalesccns, Butler, and ticketed " Dela- 

 goa Bay." This example is white, with the inner-marginal black of 

 the fore-wings well developed, and the hind-marginal border rather 

 broader than usual, — the white spots in the latter (with the exception 

 of the two largest) being almost obsolete ; in the hind-wings both the 



^ The pale lemon-yellow coloured ? seems to be rare (its occurrence was noted by 

 Boisduval in 1836). I have seen only three specimens, respectively from Kaffraria Proper, 

 Natal, and Angola, and a coloured photograph of a fourth example which was taken by the 

 late Mr. E. C. Buxton either in Natal or Swaziland. The Natal specimen, taken by M?-. 

 J. M. Hutchinson in Weenen County, belongs to Var. A., having the underside reddish 

 very pronounced. 



- Felder's Idmais Fatma, from Kordofan (Heise d\i Xovara, Lep., ii. p. 1 89, t. xxv. f. 3, 

 1865), which I have not seen, may perhaps be an unusually small and faintly marked 9 

 of this kind ; the description and figure show that the inner-marginal baud is wholly 

 wantin?
