144 SOUTH- AFEIC AN BUTTERFLIES, 



dot, and by a short upward diffused projection meeting very broad 

 inner border of apical patch on second median nervule ; in specimens 

 where inner-marginal black extends to posterior angle a white or yel- 

 lowish spot is isolated just below lower extremity of apical orange. 

 Hind-iving : upper part of discal ray prolonged to angulation on radial 

 nervule, lower part very much broader than in $, — the whole ray more 

 or less confluent broadly on nervules w4th hind-marginal macular black 

 border. Under side. — Hind-iving and cvpical harder of fore-wing more 

 or less strongly tinged with creamy yellow ; indication of dark upper-side 

 markings not so pronounced as in ^, except termination of inner-mar- 

 ginal band of fore-wing, which is blackish. Fore-iving : basal area 

 widely suffused with pale-yellow. Hind-iving : ferruginous discal ray 

 more strongly marked. 



Variety A. $ and ^ (Omphaloidcs, Butler). 



Exp. al, ($) I in. 5^-8 lin. ; ($) i in. 5-8 lin. 



^ All the black markings more or less reduced, but especially the 

 lower portion of discal ray of hind-wing, which is never broad, often 

 diffused, and sometimes obsolescent.^ Under side. — Flind-wing and 

 ap)ical border of fore-tving more or less tinged with creamy-jnnk, — in the 

 darker specimens sparsely irrorated with brown atoms. 



$ Black markings similarly reduced, as a rule, but variable ; in 

 some examples as strongly developed as in type-form. Under side. — 

 Pinkish tinge usually deeper but duller than in ^^ ; in some examples re- 

 placed by pale creamy-brownish; hind-wing faintly striolated with brown. 



{Ilah. — Cape Colony and Delagoa Bay.) 



I am unable to separate from this variety a series of still smaller 

 specimens which I captured at Robertson, Western Cape Colony, in 

 January of 1 876 and 1 877. The $s expand only I in. 3^-6 lin., 

 and the ^ s i in. 5 lin. The former exhibit a complete gradation, from 

 one with black and well-developed longitudinal bands and a thin discal 

 ray in the hind-wing, to an individual in which all these markings are 

 wholly absent. Two similarly unhanded ^ s have reached me from 

 Namaqualand District and one from Carnarvon District. The $ s do 

 not differ in marking or colouring from the smaller ordinary ones of the 

 variety." 



The Exolc $ of Reiclie {op. cit.) seems to me identical with the 

 larger and darker examples of the $ Omphcdc. My conclusion from 

 Wallengren's description {loe. cit.), that his Achinc $ was referable to 

 the $ Omphale, has been confirmed by the loan of a typical example 

 from the Stockholm Museum. After a careful comparison of the types 

 of Mr. Butler's Omphalo'ides and JTydridus — the ^ of the latter being 

 one of my own captures at Plettenberg Bay — I was unable to keep 



^ In a single S which I captured at Plettenberg Bay all the black markings but the 

 borders of apical patch are wanting. 



^ I believe that the only Teracolus I ever .saw on the wing at Cape Town was a <J of this 

 varietj'. It was flying in the Cathedral enclosure on the 14th December 1S7S ; but my 

 attempts to capture it with a pith helmet were without success.
