South African Butterflies. 389 



? . Exp. 1 in. 3 liu. Duller and paler than S , but 

 with a stronger yellow-ochreous gloss, particularly in 

 fore-wing. Fore-iving : spots of a duller whitish, in one 

 example as in ^ , in the other all but obsolete. 



Underside. Ground-colour duller and more ochreous. 

 Fore-wing : the three spots very indistinct in one example, 

 and obliterated altogether in the other ; inner marginal 

 fuscous (as in Basuto-land J ) faint and narrow. 



Mr. Bowker notes this local species as occurring 

 among long grass and rushes, near water. Near the 

 Hermansburg Mission Station, in Natal, on the 10th 

 March, 1867, I captured six examples on the summit of 

 a lofty hill-ridge; they were flitting about the purple 

 flowers of a leguminous shrub of moderate height, which 

 was common in one spot, in company with Pyrgiis MoJlo- 

 zutza and many other butterflies. I have not access to 

 these examples at present, but to the best of my recol- 

 lection, they were closer to the Kaffrarian than to the 

 Basuto-land specimens. Both sexes of the last-named 

 have the snow-white stripe of the underside of the hind- 

 wings narrower and less bright than it appears in the 

 Kaffrarian type specimens. 



Genus IsMENE, Swainson. 



Mr. Butler hasrecently (Cat. Di. Lep. descr. Fabr. in 

 Coll. B. M., pp. 269-70) , identified with the much-debated 

 Fabrician genus Hesperia, the generally received species 

 of Ismene, such as I. Iphis, Pisistratus, and Helirius, but 

 merely notes, ^'The description applies best to Hesperice 

 UrbicolcB of Fabricius.^* 



Ismene Florestan. 



Papilio Florestan, Cramer, Pap. Exot. iv. 210, pi. cccxci.

Mr. Bowker observes that this species- was rather rare 

 at Maseru : it visited the flowers in his garden, both 

 morning and evening. A specimen received from Basuto- 

 land presents no variation from the generality of examples. 

 Both in Natal and near Grahamstown, I found this but- 

 terfly visiting flowers a little after sunset, as well as during 

 the heat of the day.
