1907.J BUTTERFLIES OF THE FAMILY LY0.*:NID.'E. 601 



Thecla purpuriticus, sp. n. (Plate XXXVI. fig. 2.) 



Male. Allied to T. empusa Hew.*, which it closely i-esembles on 

 the upper side. On the under side the ground-colour is darker ; 

 the red crown to the black marginal spot between the lower 

 median nervules on the hind wing is entirely absent and the 

 orange area is much more extensive, the submarginal shades being 

 placed further in and close to the linear band. 



Female. Differs only from the male in the black area on the 

 upper side being slightly duller. 



Expanse 14 inch. 



Hah. Interior of Colombia {J. Carclei-). 



Types, Mus. Druce. 



There is also a male in the British Museum from Bogota. 



Thecla gentiana, sp. n. (Plate XXXYI. fig. 1.) 



Male. Much like T. tarena Hew.f, but fore wing above with a 

 large, distinct, deep black oval patch, occupying the outer half of 

 the cell and inwardly bordered by a dark grey patch of differently 

 placed scales, the blue area being reduced to the extreme base. 

 Under side : ground-colour pale brown with sordid white linear 

 bands as in T. tarena, but straighter and less prominent, and the 

 red spot between the lower median nervules placed nearer to the 

 margin. 



Expanse 1^ inch. 



Hah. Bogota, Colombia. 



Type, Mus. Druce. 



Although this insect is much like T. tarena Hew. and T. em- 

 pusa Hew. at first sight, a closer examination shows it to be quite 

 distinct, and it may eventually prove to be not very nearly allied. 



Messrs. Godman &, Salvin have given the synonymy of T. em- 

 pusa in B. C.-A., Rhop. ii. p. 61. 



Thecla philinna. 



Thecla pkilinna Hew. Descr. of Thecla, p. 19 (1868); 111. Diur. 

 Lep. p. 138, pi. 55. figs. 334, 335 (1873). 



Tmolus unilinea Kaye, Trans. Ent. Soc. 1904, p. 192. 



This is a variable species on the under side, some specimens 

 haviug the ground-colour almost pure white, whilst the spots on 

 some are rich dark brown and on others vary to golden yellow, in 

 some specimens very prominent and in others much reduced in 

 size and intensity. I have examined Mr. Kaye's type in the 

 British Museum, and feel certain that it is only an extreme form. 



Mr. Godman's collection contains a good series from Mexico 

 (Atoyac, Vera Cruz, May, H. H. 8.) to S.E. Brazil, including one 

 female from Panama (Oalobre, Arce) marked on the under side 

 like Mr. Kaye's type.
