known forms of South African Butterflies. 243 



characters last mentioned L. lerothodi shows some resem- 

 bhxnce to X. methymna (some specimens of which are also 

 almost as dark on the upper-side), but is widely separated 

 by its unvaried (except at apices) cilia, and the yellow tinge 

 of the under-side with its much more constricted discal 

 markings. 



Described from 3 ^ <^ and 3 $ %* in the British Museum 

 (Natural History), received from Mr. R. Crawshay, in a 

 collection of butterflies made by him in Basiitoland in 

 the years 1901-2. From Mr. Crawshay's detailed labels 

 attached to the specimens, I find that these six examples 

 of L. lerothodi were all taken on the Machacha, the highest 

 mountain in the Maluti range, a $ and a $ having been 

 secured at each of the following elevation?, vid : 9,000, 

 9,500, and 10,000 feet, on the 29th, 30th, and 31st 

 January, 1902, respectively.

Of this abundant South-African form, variable in the 

 male and exceedingly variable in the female, I wish to 

 record a singularly pale Aberration of the $ from Natal, and 

 a highly remarkable melanic one of the $ from Cape 

 Colony. 



Aberration. — ^. Ground-colowr of upper- side {and also that of 

 under-side offore-ioing) very pale dull yellowish-crearay, with a greyish- 

 tinge in hind-wing ; central spot in hind-wing very dull pale orange- 

 yellow. On under-side the hind-wing and the costal and hind- 



* Two of these examples have lost the fore-legs, but from tlie 

 features presented by the abdomen and wings, there can be little if 

 any doubt tliat they are ^ $ .
