244 Mr. R. Trim en on some neio w imperfectly - 



marginal borders of the fore-wing very pale greenish with a tinge 

 only of yellow. 



This example furnishes a striking contrast to the normal 

 deep orange-yellow ^ Eledra — the more so as it wants the 

 pink or violaceous-pink surface-lustre — and recalls to some 

 extent the appearance of the pale dimorphic form of the $. 

 The markings on both surfaces are normal. 



Mr. C. N. Barker took this specimen at Malvern, near 

 Durban, Natal, and most liberally presented it to me with 

 the rest of his South -African Lepidoptera in 1898.* 



Aberration.- — §. Ground-colour of iipper-side (as well as that of 

 under-side of fore-tvi7ig) replaced by dull fuscous, which exhibits, 

 however, the normal violaceous surface-lustre ; the darker borders 

 and disco-cellular terminal spots obscurely indicated. On xmder-side 

 the bind-wing and a more limited than usual apical area in the fore- 

 wing are of a very dingy olivaceous-greenish ; central silvery mark- 

 ing in hind- wing rather small but conspicuous ; other spots obsolete 

 or obsolescent. In size this $ is only Ih in. across the expanded 

 fore-wings, — over 4 lin. below the average. 



Mr. R. M. Lightfoot, of the South-African Museum, wrote 

 to me in February 1902 about an extraordinary " bluish- 

 black " Colias taken near Cape Town, by Mr. A. Duncan ; 

 and this is the example here described, which has been 

 forwarded to me by the captor through Mr. Feltham. The 

 last-named correspondent informs me that Mr. Duncan 

 took it at Groote Schuur, on the slopes of the Devil's Peak 

 above Rondebosch in August 1901, and that he had heard 

 of the capture there by another gentleman of a second 

 similar example at about the same time. 



To afford a clear appreciation of the nature of these two 

 Aberrations, I give figures of G. clectra ( $ and both forms 

 of $ ) from Natalian specimens collected at Malvern near 

 Durban by Mr. C, N. Barker, which are good average 

 representatives of the species, except that the second (pale) 

 form of $ is larger than usual, expanding 3| in. Hitherto 

 Eledra has remained unfigured, except by the rough 

 delineations of Cramer published 120 years ago ; and the 

 illustrations now given will render much plainer the char- 

 acters in which the butterfly agrees with or differs from its 



* In 1894 I was shown at Cape Town a somewhat similar ^^ said 

 to have been recently taken in the suburb of Rondebosch. The 

 specimen was much rubbed on the upper-side, but retained sufficient 

 scales to show that it had been of a singular pallid tint resembling 

 that of the second form of $ ,
