1907.] BUTTERFLIES OF THE FAMILY LYaENID.E. 621 



Thecla furcifer, sp. n. 



Male. Closely allied to T. una Hew.* Upper side much as in 

 that species, but white areas of hind wing suflused with pale 

 greyish blue. Under side pale grey, with sordid-white-edged 

 bands and spots, slightly darker than the ground-colour, arranged 

 as in T. una. The red crowns to the black dots on margin near 

 anal angle of hind wing are absent. 



Expanse 14- inch. 



Rab. Espiritu Santo, Brazil. 



Type, Mus. Druce. Also in the British Museum. 



The female of T. una has more extensive white areas, and in 

 some specimens whitish tips to the fore wings. 



Thecla cleon. 



Fa2nUo cleon Fab. Syst. Ent. p. 522 (1775). 



Tniolus cleon Butl. Cat. Fab. Diur. Lep. p. 188, pi. ii. figs. 4-6 

 (1870). 



Thecla cleon Hew. 111. Diur. Lep. p. 142, pi. 56. figs. 347-349 

 (1873). 



T. ecbatana Hew. ibid. pi. 40. figs. 525, 526 (1874). 



I have examined the type in the Banksian cabinet, and although 

 it is in a very bad state of preseiwation there is enough of it 

 remaining for identification. I have no doubt that it is a female, 

 and that the males only have the inner margin of the fore wings 

 blue. There are a number of specimens before me from the 

 Amazon regions, and we have recently received examples from 

 Ti'inidad (Birch). 



On the under side the males appear to be always clouded, 

 especially towards the base, and in both sexes there is a mark 

 closing the celhin both wings. 



Thecla picextia. 



Thecla picentia Hew. III. Diur. Lep. p. 138, pi. 55. figs. 328, 329. 



Hah. Tapajos, Amazons. 



The female only appears to be known, and the type is now in 

 Mr. Godman's collection, which also contains another specimen 

 considered by Bates to represent the same species. It does not, 

 howevei', agree very well, as the ground-colour is darker and the 

 transverse bands are redder, and in the fore wing narrower and 

 in the hind wing wider. The red spot on the hind wing between 

 the lower median nervules is also much larger. 



The British Museum Collection contains a male which may 

 possibly prove to be T. picentia. On the upper side it is wholly 

 dark brown, with a darkei- patch at the end of the cell of the fore 

 wing, and on the under side the ground-colour is greyer and the 

 bands are narrower and more sinuous. It is labelled " Bogota," 

 and if it should prove distinct may be named Thecla ruhifer. 

 The head, the space between the eyes, and the base of the costa
