Case of Pdpilio Merope. 153 



$. (Variations intermediate between the several Forms above enume- 

 rated) : — ♦ 



A. Between Forms 1 (Cenca) and 2 (analogue of Hippucoim, 



Fab.) 



a. P. Merope, Butler ( $ , P. Cenea, var.), in Trans. Ent. 



Sac, loc cit., p. 275. 

 [This individual is very close to the typical Cenea, 

 but in the shape and position of the very re- 

 stricted patch in the hindwings resembles the 

 individual (b) immediately following hereunder. 

 Hah. Grahamstown, Cape Colony.] 



b. P. Merope, Tr'imen ( $ , variation), in Trans. Linn. Soc, 



loc. cit., f. 2. 

 [All the markings in this individual are dull white. 

 The forewings have the sub-apical bar of the 

 Hijjpocpon-Vikc form, and an inner-marginal 

 patch strictly intermediate in size and shape be- 

 tween those of the latter form and of the Cenea 

 form respectively. The patch of the hindwings 

 is much narrowed by a fuscous basal suffusion. 

 Hab. Tsomo River, Kafifraria.] 



B. Between Forms 2 (analogue of H'lppocoon, Fab.) and 3 



(^Trophonius, Westw.) 



c. P. Merope, Trimen ($, vaiiation),in Trans. Linn. Soc, 



loc. cit., p. 510, note.'] 

 [This specimen has the ordinary markings of the 

 forms which it links, excepting that the patch of 

 the hindwings, though not obscured at the base, 

 is decidedly narrower. All the markings are 

 tinged with faint, dull, ochreous- yellow. Hah. 

 St. Lucia Bay, South Eastern Africa.] 



Additional valuations to those above recorded are ( 1 ), 

 the white-marked specimen from Knysna, described in this 

 paper {vide supra, p. 150, note), which might stand between 

 a. and b. ; and (2), the striking variation of Trophonius, 

 which has the sub-apical bar of the forewings considerably 

 broader than usual, and yellowish hrick-red instead of 

 Avhite. The field of red common to both wings differs 

 from that ordinarily presented in being darker (inclining 

 to ferruginous) and smaller, in the forewings not reaching 

 to the median nervure, and clouded Avith fuscous between 

 that nervure and the sub-median nervure. A very fine 

 example of the latter Avas taken in the Division of Bathurst, 

 Cape Colony, by Miss Mary Barber, in March, 1870. 



• P. CepJwnius, Hpffr. (Stett. Ent. Zeit., 1866, pp. 131-2," according 

 to " Zoolog. Record, 1866, p. 451), is unknown to me, but may be one of 

 these linking variations. Mr. Kirby gives it under P. Merope as 

 " Var. a," in his Catalogue of Diurnal Lepidoptera (1871). Mr. Weale's 

 " peculiar Hippocoon form " (see above, p. 144) should be included 

 under " A," and immediately follow " b," in the list of variations here 

 given.
