io8 SOUTH-AFRICAN BUTTERFLIES. 



distinct. Hind-ioing : disco-cellular spot dusky, diffused ; discal ray 

 ouly represented by a short brownish streak from costa to second sub- 

 costal nervule ; orange costal edging almost obsolete. 



$ White, somewhat yellotv-tinged generally or from bases only ; apical 

 patch of fore-wing bright orange-red, wider than in Speciostis, and emitting 

 rays along subcostal nervure and two radial nervules as far as extremity 

 of discoidal cell, the inner black border being very much narrowed and 

 obsolescent in its middle part. Fore-ioing : terminal disco-cellular spot 

 very small ; basal clouding narrow and faint ; discal spot very much re- 

 duced, diffused, or obsolescent ; cuneiform black spots transversing apical 

 red not so near its inner edge as in Spcciosus. Hind-iving : basal cloud- 

 ing very faint and restricted ; discal ray obsolescent except on costa ; 

 hind-marginal blackish border very much narrower and diffused, partly 

 or entirely broken into separate spots. Under side. — Hind-wing and 

 apical patch of fore-wing not pink-tinged, hut the former rendered darker 

 than in $ hy closer and stronger striolation, and the latter flushed with 

 reddish and traversed by the usual series of blackish spots. Hind- 

 wing : disco-cellular terminal spot small but distinct, immediately sur- 

 mounted by a rather conspicuous whitish spot ; discal ray dark-brownish 

 rather strongly marked as far as third median nervule. 



Dimorphic Form of $. — Apical patch of fore-tving black, as in cor- 

 responding form of % Bpcciosns, hnt white spots of scries traversing it 

 comparatively larger and not so widely separated. Under side. — Duller 

 in tint ; discal ray of hind-wing with macular traces of its inferior 

 continuation. 



In one $ of this form the discal spot of the fore-wings beyond 

 middle and the hind- marginal spots of the hind-wings are exceedingly 

 reduced, and in another those markings are so faint and minute as to 

 be scarcely perceptible. 



The characters given serve very well to distinguish this small 

 violet-tipped Tcracolus from Speciosus, but it must be noted that examples 

 occur (I have before me four $ s and a $ of each form) which show 

 certain features intermediate between those of Jobina and Speciosus. 

 These $ s are a little larger than Jobina proper, and have the black 

 borders of the apical violet broader, and the cilia of the hind-wings 

 white throughout ; and both sexes have the under-side colouring much 

 yellower, with scantier striolation of the hind-wings. Two of these 

 $ s and the two $ s were taken by the late Mr. M. J. M'Ken at 

 D"Urban, Natal, late in April 1867. 



Jobina seems to occur solely as a winter (or dry-season) butterfly. Apart 

 from the non-typical individuals just mentioned as captured in April (which 

 are, however, much nearer to true Jobina than to Speciosus), all the specimens 

 wliose dates of capture are known to me were taken in May, June, July, and 

 August. I never saw this small form during my summer visit, Avhich ended 

 on April 9th ; nor, on the other hand, am I aware of Speciosus' appearing on 

 the wing except in the summer or Avet season. It seems not impossible 

 that the two butterflies may turn out to be summer and winter broods of
