South African Butfcrjlies. 379 



Mr. Butler mentions (Cat. Di. Lep. desc. Fabr. in C'oll. 

 Brit. Mus. p. 205) that, in tlie Banksiau Collection, 

 tlie P. Mesentina of Cramer is queried as Hellica, Linn . ; 

 but the detailed description in Mus. Lud. Ulr. gives the 

 characters of four white spots at the apex of the fore- 

 wings, and the underside of the hind-wings, 'Wenis 

 reticulat^e latis, cinerascentibus, desinentUms posterius in 

 ranios 6 s. 7, lanceolate s ," which do not at all apply to 

 Mesentina. Linnets omission to mention the yellow 

 margining of the gray-clouded nervures, may have arisen 

 from his having a worn or faded example before him. 



Boisduval remarks, that P. Glauconome, Klug, from 

 Egypt, Arabia, and Mount Sinai, " fait le passage d' Hel- 

 lica ;\ Dajdidice" (Sp. Gen. i. 546). On a cursory 

 examination of Klug's figures, 1 thought Ghuicoiiome to 

 be probably a small variety of Hellica.

A single example was received from Koro-Koro. 



1 had the pleasure of meeting this beautiful species in 

 life, for the first time, at Highlands, near Grahamstown, 

 at the end of January, 1870, and during the following 

 month met with it not uncommonly. It frequented 

 steep hill-sides on the edges of Avoods, but never entered 

 the shade of the woods themselves, delighting in the 

 Scahiosa flowers, which were abundant in such stations. 

 It is very conspicuous on the wing, and is easily cap- 

 tured, being rather slow of flight, and settling frequently. 

 I afterwards saw the species on the wing, near Uiten- 

 hage. 



Mr. McKen has forwarded fine examples of this butter- 

 fly from Natal, where Mr. Harford has also met with it. 

 It appeared, also in a collection made at Potchefstroom, 

 Trans-Vaal, by Mr. V. E. Noren ; and, in 1867, Mr. 

 Hewitson showed me an example from the Zambesi. 



I have been unable to discover any characters to dis- 

 tinguish the Tritogenia of Klug, (Symb. Phys. pi. viii. 

 f. 18, 19), from Eriphia, and do not know what led 

 Boisduv^al to separate the two in his " Species General" 

 (i. 513).
