io8 SOUTH-AFRICAN BUTTERFLIES. 
distinct. Hind-wing : disco-cellular spot dusky, diffused ; discal ray 
only represented by a short brownish streak from costa to second sub- 
costal nervule ; orange costal edging almost obsolete. 
? White, somewhat yellow-tinged generally or from bases only ; apical 
patch of fore-ioing hright orange-red, wider than in Speciosus, 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-wing : 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 Speciosus. Hind-wing : 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-iving not pink-tinged, hut the former rendered darker 
than in $ hij 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-ioing Uack, as in cor- 
responding form of $ Speciosus, hut 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 Teracolus from Spieciosus, 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 Johina and Speciosus. 
These $ s are a little larger than Johina 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. 
Johina 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 Johina than to Speciosus), all the specimens 
whose 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, which ended 
on April 9th ; nor, on the other hand, am I aware of Speciosus' appearing on 
the wing except in the summer or wet season. It seems not impossible 
that the two butterflies may turn out to be summer and winter broods of
