entire fore wings black with the discal spots conspicuously white), 

 that, having only the descriptions to refer to, I was inclined to 

 think that the female received by Mr. Butler had been erroneously 

 associated with Mr. Godman's female. But on consulting Mr. 

 Butler 1 , he most kindly sent me figures and notes which leave no 

 doubt of the specific identity of these widely differing sexes. 



There are only two examples of this curious Planema in 

 Mr. Selous's collection, one captured at Umtali, and the other (on 

 February 24th) in Christmas Pass. The former is so much 

 smaller, and has the hind margin of the fore wings so much more 

 hollowed, than the latter, that I took it for a male although 

 entirely of the female coloration ; but closer examination has 

 shown it to be a female. Mr. Butler, however, informs me that 

 during 1892 he had seen both males and females in a collection 

 from Kiliraa-njaro, and that one or two of the males were less 

 unlike the female than the rest, the ochre-red covering the basal 

 half only of the fore wings 1 . 



The resemblance borne by the female to Amauris echeria (var. 

 albimaculata, Butl.) is very stroug, but I hesitate to adopt 

 Mr. Butler's conclusion that the former is evidently modified in 

 imitation of the Amauris, because, firstly, both Amauris and 

 Planema are equally protected genera and extensively mimicked by 

 Butterflies of other groups, and, secondly, P. johnstoni female does 

 not either in pattern or colouring diverge much from its congeners, 

 coming near P. hjcoa, Fabr. 



Mr. Selous notes that he saw only a few of this Butterfly ; they 

 flew on the border of a stream and settled very frequently.

 Of this most widely ranging species there are five specimens 

 from Christmas Pass and one from the Mineni Valley. 



1 Acrosa proteiua, 0. Oberth. (Etudes d'Ent. xvii. p. 25, pi. i. fig. 4 ; pi. ii. 

 figs. 14, 19, 21 ; pi. iii. fig. 29), is apparently synonymous with P. johnstoni, 

 the specimens recorded and figured being from Urogaro and Usambara in East 

 Africa. Mr. Selous's two examples agree pretty nearly with M. Oberthur's 

 fig. 14 on pi. ii., but one of them is considerably larger and with the median 

 space in the hind wings of a much deeper tint of yellow. The species appears 

 to be highly variable, M. Oberthiir figuring (pi. i. fig. 4) a small male agreeing 

 with the ordinary female except that the spots of the fore wings are pale yellow 

 instead of white ; (pi. iii. fig. 29) a female in which the hind wings on both 

 surfaces, and the hind-marginal area of the fore wings on the underside, are 

 deeply tinged with roddish-ochreous ; and (pi. ii. figs. 19 and 21) a male of the 

 typical (johnstoni) "colouring, and a female in which the reddish-ochreous is 

 strongly prevalent disoally on both surfaces of both fore and hind wings. It 

 will probably be found that in this species of Planema, as in P. csebria (see 

 S.-Afr. Butt. i. pp. 177-78), the varieties are resolvable into two or three in 

 which (he sexes more or less agree in coloration.
