1907.] BUTTERFLIES OF THE FAMILY LYCJENIDiE. 585 



Thbcla buccina, sp. n. (Plate XXXIY. fig. 4.) 



Male. Allied to T. voltinia Hew. ; brand moi-e circular. Colour 

 approaches that of T. ligurina Hew., but more steely ; on the 

 under side the ground-colour is a warmer shade of brown, and 

 the inner white line on the hind wing appears to be nearer to the 

 outer margin. 



Expanse Ig-ly'y- inch. 



Hab. Cha-pada [H. H. Smith), Tapajos {Bates), Brazil. 



Type, Mus. Godman. 



This insect was separated by Bates from its allies, but it does 

 not appear to have been described. 



Thecla nitor, sp. n. (Plate XXXIV. fig. 5.) 



Male. Allied to T. 2)unctimi Herr.-Schiifl'.*, which it resembles 

 on the upper side. On the under side the ground-colour is rich 

 plumbeous ; there are no markings on the fore wing, and on the 

 hind wing the inner white linear band is very prominent and less 

 inclined to break up into spots ; the submarginal row of spots is 

 almost obsolete and the red patches are much reduced ; the 

 extreme base of the hind wing also is red. 



Exj)anse 1| inch. 



Hab. Ega, Amazons [Bates). 



Type, Mus. Godman. 



This may jDrove to be but an aberration of T. punctxim, but it 

 is so difierent in appearance on the under side that I venture to 

 name it. 



Thecla murex, sp. n. (Plate XXXIY. fig. 6.) 



Male. Allied to T. mycon G. & S.f On the upper side the brown 

 brand in the cell is much larger, the blue areas are much duller 

 and darker, and the apex and outer margin of fore wing are broadly 

 black. On the under side the ground-colour is lighter and the 

 linear band on the hind wing is less angulated. 



Expanse li inch. 



Hab. Rio Grande, Brazil. 



Type, Mus. Druce. 



Doubtless the southern representative of T. mycon. 



Thecla caninius, sp. n. 



Male. Allied to T. thyesta Hew. Upper side : fore wing dark 

 brown, with a black brand at the end of the cell followed by a 

 smaller, paler brand, the inner margin only pale opalescent blue ; 

 hind wing opalescent blue with the costal half dark brown. 

 Under side : ground-colour paler, marked much as in T. thyesta, 

 but the linear markings fainter and apparently nearer to the outer 

 margins and without the whitish shading towards the anal angle. 



Ex]3anse 1 inch. 



Hah. Venezuela.
