42 SOUTH-AFRICAN BUTTERFLIES. 



vao-uely witli a greyish-wLiite shade along its upper half ; sometimes 

 a ray of chrome-yellow along submedian nervure from base. 



Variety of $. — (Var. Flavida, Grandidier.) — More or less tinged 

 ivith lemon-yelloiv, especially near margins : hind-marginal hlackish 

 border much narroiver {especially in hind-wing) and more sharply den- 

 taied inwardly ; hasal Uachish of fore-wing all wanting except a narrow 

 faint hasi-costal horder, which scarcely enters discoidal cell (except 

 very slightly and diffusedly at base and along its upper edge), and 

 terminates somewhat truncately a little before extremity of cell. 

 Fore-iving : subapical spots in border yellowish. Hind-wing: basal 

 irroration wanting or very slight and restricted ; hind-marginal border 

 less than half as wide as in typical $, its inner edge much better 

 defined, and prominently (in one example acutely) dentating the ground- 

 colour on nervules. Under side. — Hind-wing and apex of fore-wing 

 more creamy in tint ; blackish border considerably narrower and duller 

 in fore-wing, and scarcely perceptible in hind-wing. Fore-wing : no 

 cellular blackish (except, in one specimen, the very faintest trace along 

 upper part of cell). 



In this butterfly the dissimilarity of the sexes is so extreme that 

 one cannot wonder at Boisduval's treating them originally (1833) as 

 distinct species. The variety of the $ just described was, however, at 

 first regarded by that author as the $ of the ty^Dical $, which he 

 named Mcdatha ; but this was rectified in the Species Gdoidral (1836), 

 which recognised that Orhona and Malatha were ^ and $ of one 

 species, and noted the so-called ^ of Malatha as a form of the $. 



I have examined the type of Sala in the Banksian Collection at 

 the British Museum. It is a small but broadly black-marked $ from 

 " Sierra Leone." The $ figured by Cramer as Epaphia (stated to be 

 from the same locality) is very broadly black-marked, and is repre- 

 sented as possessing an orange basal suffusion in discoidal cell of the 

 fore-wing, and also a broad orange suff'usion (outwardly fading into 

 yellow) between the nervures in the basal half of the hind-wing. 

 Drury's Eypatia is also a " Sierra Leone " $ ; it is larger than Cramer's 

 specimen, and is figured as having a tinge of yellow over the basi- 

 inner-marginal part of both wings on the upper side, and the border 

 of the hind-wing narrower than in Cramer's figure ; while, on the 

 under side, the suffusion of the cell in the fore-wing is pale ochreous- 

 yellow, and there is scarcely a trace of the orange and yellow rays 

 in the hind- wing. Godart's description of a ^, likewise from Sierra 

 Leone, accords better with Drury's than with Cramer's figures. Neither 

 of the fio-ures just mentioned exhibit the junction in the fore-wing of 

 the disco-cellular with the hind-marginal blackish (on third median 

 nervule), which usually occurs in the Natalian and Delagoa Bay speci- 

 mens of the typical $. 



I do not remember to have seen, nor have I found auy record of, 

 any $ examples linking the variety Flavida with the typical $ ; but
