2 48 SOUTH- AFRIC AX BUTTERFLIES. 



$ Third Form {Trophonius, Wostw.).-^ Pattern of Second Fcn'm, 

 hut large patch in both wings tvider, and pale bricJc-red instead of ivhite. 

 Fore-ioing : disco-cellular oblique white streak usually longer and 

 wider ; small subapical white spot rarely well expressed, sometimes 

 very minute, often altogether wanting ; subapical oblique white bar 

 as in Second Form, but sometimes with a creamy-reddish tinge ; inner- 

 margiual brick-red patch usually extending close to base and over 

 median nervure into discoidal cell. Hind-iving : patch usually ex- 

 tending to base itself (but rarely with a very narrow blackish suffusion 

 there), and externally nearer to hind-margin, — its outer edge not so 

 conspicuously marked with dark neuration and inter-nervular rays ; a 

 few of the submarginal spots sometimes tinged with creamy-reddish. 

 Undeu side. — Bo7rlcrs of ivings as iji Second Form ; in other ixsjyects the 

 pattern and coloration of upper side is reproduced, tvith the hrick-rcd 

 rather pcdcr and duller ; dark neuration and inter-nervidar streaks not 

 strongly marked. 



Coloration and markings of head and body as in ordinary $. 



In addition to the three prominent and very distinct forms above 

 described, the $ P. Ccnea presents numerous intermediate and other 

 variations, of wliich the following are the principal instances that have 

 come under my notice, viz. : — 



A. Between Forms i (Cenea) and 2 (analogue of Hippocoon Fab.).

P- ^75- ... 



This individual is very close to the typical Ceiiea, but in the 



shape and position of the very restricted i^atch in the hiiul- 



Aviugs resembles tlie individual (c) following liercunder. — Hah. 



Grahamstown, Cape Colony. 



h. P. Cenea, Trim. ( 9 , variation), Trans. Ent. Soc. Land., 1874, y. 



150, note. 



All the upper-side markings in this specimen are white, and 

 though answering to those of the HijjpocooTi-like form, are so 

 reduced and attenuated as (with the single exception of the 

 very much narrowed and dentated subapical bar of the fore- 

 wings) more to resemble those of the white-spotted variety of 

 Cenea. — Hah. Knyana, Cape Colony. 



c. P. Merope, Trim. ( $ , variation), in Trans. Linn. Soc., loc. cit., f. 2. 



All the markings in this individual are dull white. The fore- 

 wings have the subapical bar of the Hijypocoon-WkQ form, and 

 an inner-marginal patch strictly intei-mediato in size and shape 

 between those of the latter form and of the Cenea form respec- 

 tively. The patch of the hind-wings is mucli narrowed by a 

 fuscous basal suffusion. — Hah. Tsomo Eiver, Kafharia (/. H. 

 Boivker). 



d. P. Cenea, Trim. ( $ , variation) [ = P. Merope, peculiar Hippocoun 



form, J. P. Mansel Weale], Trans. Ent. Soc. Lond., 1874, p. 144. 

 In the fore-wings botli the subapical white bar and tlie inner- 

 marginal white patch are considerably smaller and narrower 

 than in the ordinary Southern Hip)pocoon, the latter marking
