ffab. Rio Grande, Chapada Oampo, Brazil {II. If. Smith). 

 Castro, Parana {E. D. Jones). Paraguay [B.M.). 

 Type, Mus. Druce. 



Mr. Jones has shown me sevei'al specimens captured by himself. 

 It is also allied to T. gadira Hew. 



Thecla attalion. 



Thecla attalion Godm. & Salv. B. C.-A., Lep. Rhop. ii. p. 60, 

 pi. 55. figs. 19, 20 (1887). 



This will probably prove to be the male of Hewitson's 

 T. quaderna*, which again does not appear to differ from the 

 previously described T. ketaf Edwards. Very few examples of 

 this group, for which the generic name Erora has been proposed 

 by Scudder, are to be found in collections, and before sinking any 

 of these names it is advisable to await the arrival of more 

 specimens. 



Thecla smaragdus, sp. n. (Plate XXXV. fig. 13.) 



Male. Upper side : dull violaceous brown. Cilia brown, 

 outwardly whitish. Under side pale emerald-green ; fore wing 

 with a, fine white line from the costa to the lower median nervule ; 

 hind wing with a much broken fine white line from the costal to 

 inner margin, where it is inwardly bordei'ed with a faint black 

 streak. A small red patch at the anal angle. Cilia of both wings 

 black outwardly edged with white. 



Expanse j^^- inch. 



Rah. Chapada, Brazil (ff. H. Smith). Castro, Parana 

 {E. D. Jones). 



Type, Mus. Godman. 



Allied to T. hihlia Hew. and T. ares G. & S., but at once dis- 

 tinguished by the black cilia below. 



Mr. E. Dukinfield Jones's collection contains a specimen of this 

 species. 



Thecla sesara. 



Thecla sesara Godm. & Salv. B. C.-A., Lep. Rhop. ii. p. 722, 

 pi. 111. figs. 7, 8(1901). 



Type, Mus. Schaus. 



The name " sesara " has been previously given to a species 

 belonging to another group of Thecla (B. C.-A. p. 90), but as both 

 may eventually be placed in difierent genera, I refrain from 

 suggesting another name. 



Thecla selina. 



Thecla selina Hew. 111. Diur. Lep., Lye. p. 118. pi. 50. fig. 255, $ . 



Hewitson separated this insect from T. pholeus Cr. principally
