Genus Colias, Fabricius. 



CoUas Electra. 

 Papilio Electra, Linn. S. N, ii. 764. 



This species seems universally distributed throughout 

 South Africa, and extends into the tropical region on 

 the Western side, Mr. J. A. Bell having brought two 

 specimens from Damara-land in 1862. It is very numer- 

 ous in Basuto-land, and tlie pale form of the ? appears 

 often to occur there. 



There is probably no genus of butterflies that ranges 

 over all latitudes to such an extent as Colias, for even 

 Pyrameis is not recorded from such extremes of North 

 and South as Labrador (C. Felidne) and Patagonia (C. 

 Leshia) , Lapland (C Bootliii) , and the Cape. Mr. Bates 

 (Jouim. Entom. i. 230) observes that in tropical America, 

 the genus is confined to the highest plateaux of Colum- 

 bia;* and I am not aware that any species occurs in 

 tropical North-Africa, or tropical Asia, with the excep- 

 tion, in the latter region, of C. Nilagiriensis, Felder, 

 the Indian species generally being Himalayan. 



Sub-fam. Papilionin^. 



Genus Papilio, Linn. 



Papilio Demolc%iS. 



Linn. S. N. ii. 753. 



This is the most widely-spread Papilio in Southern 

 Africa, and the only one of the genus that extends to 

 Cape Town. Two S sent from Maseru are unusually 

 small, one expanding 3 in. 2 lin., and the other barely 

 2 in. 9 lin., the bodies being of proportionate size. Mr. 

 Bowker observes that individuals of this dwarfed stature 

 are not uncommon in Basuto-land, but that specimens of 

 various sizes, up to the ordinary one (exp. about 4 in.), 

 also occur there. 



* Colian Cef^onia, Stdll, (which, bowevcr, coustitutes an isolated section 

 of the gemis) is recorded from Mexico, us well as from several of the West 

 Indian Islands.
