1907.] BUTTERFLIES OF THE FAMILY LYCiENID^. 623 



Thecla AZIA. 



Thecla azla Hew. 111. Diur. Lep., Lyca?nidpe, p. 144, pi. 57. 

 figs. 357, 358 (1873). 



Thecla nipona Hew. ibid. p. 204, pi. 81. figs. 673, 674,675(1877). 



Mr. Grose Smith has kindly shown me his type of T. nipona, 

 and I have no hesitation in sinking this name as a synonym. 



Mr. Godman's collection contains a large series from Mexico to 

 S. Paraguay, showing all intermediate forms together with typical 

 forms from various localities. 



Hewitson states that his figure of T. azia represents a male, 

 but I am inclined to think that the absence of the dark discal 

 spot on fore wing indicates a female. 



Thecla volumex, sp. n. 



Upper side uniform dull brown, a minute red spot in the lobe. 

 Tail black tipped with white. Under side : ground-colour and 

 markings much as in T. jncentia Hew. 



Expanse |- inch. 



ITab. Rio, S. Brazil ; Chapada Camjjo, Brazil (ZT. H. Smith). 



Type, Mus. Druce. 



This obscure insect, although much like T. 2ncentia Hew. on 

 the under side, has one tail only, and that on the lower median 

 nervule, as in T. azia Hew. The specimen from Chapada Campo 

 was captured in January and is in Mr. Godman's possession. I 

 cannot satisfactorily determine the sex of the specimens described, 

 but I believe them to be males. 



Thecla vidulus, sp. n. 



Male. Upper side : fore wing uniform dull black ; hind wing 

 cjerulean blue gi'adually blackening towards the base ; costal 

 margin and extreme apex dull black. Under side : bands and 

 markings as in T. cinniana Hew., but ground-colour darker and 

 red band on hind wing very much wider. Two parallel red lines 

 closing the cell of hind wing. 



Expanse 1|- inch. 



Hah. Ecuador. 



Type, British Museum (Hew. Coll.). 



Apparently allied to I', cinniana, but a much larger insect. It 

 was placed by Hewitson in his cabinet without a name, and was 

 probably collected by Buckley. 



Thecla rufo-fusca. 



Thecla rufo-fusca Hew. 111. Diur. Lep. p. 96, pi. 78. figs. 627, 

 628 (1877).' 



Thecla lucaris Weeks, P. New Eng. Zool. Club, vol. ii. p. 102 

 (1901); 111. Diur. Lep. p. 42, pi. 10. fig. 1 (1905). 



Described by Hewitson from an unknown locality. Ranges 

 from Mexico to Brazil and the West Indies. Mr. Weeks's figure 

 appears to be that of a male, and is an excellent representation of 

 the insect described by Hewitson.
