Thecla purpurantes, sp. n. (Plate XXXY. fig. 7.) 



Male. Allied to T. foyi Scliaus*, from which it clifiers on the 

 upper side in the blue being of a greener shade and the lobe black, 

 not orange as in that species. On the under side the black and 

 white linear band on the hind wing is more angulated and more 

 distinct. On the fore wing the glandular patch is silky, opalescent, 

 sti-aw-colour, darker towards its centre. 



Expanse If inch. 



Hah. Peru. 



Type, Mus. Druce. 



There is also a specimen in the British Museum from the 

 Crowley Bequest. 



Specimens of T.foyi have been placed in the British Museum 

 by Mr. Schaus, with which I have compared those now before me. 



Thecla phoster, sp. n. (Plate XXXV. fig. 8.) 



Male. Allied to T. ostrinus and T. cT/Mfflrws, from which latter it 

 is not distinguishable on the upper side, having the red spot in 

 the lobe. On the under side the ground-colour is much darker and 

 more shiny. The glandular patch is larger and of much the same 

 shade as the wings, whUst the silky scales surrounding it are much 

 rougher in appearance and are more extensive. On the hind wing 

 the submedian band is very prominent and more inclined to be 

 broken up into separate spots.

 large darker glandular patch below the cell which is wholly pale 

 opalescent blue ; an ultramedian whitish linear band, from near 

 the costa to the lower median nervule, and some submarginal 

 whitish shades which become more prominent towards the outer
