624 MR. H. H. DRUCE ON NEOTROPICAL [June 18, 



Thecla syllis. 



Thecla syllis Godm. & Salv. B. C.-A., Lep. Eliop. ii. p. 92, 

 pi. 58. figs. 6, 7 (1887). 



We possess a male from the interior of Colombia, and Mr. 

 Godman's collection contains another from Tapajos obtained by- 

 Bates. 



Thecla ceromia. 



Thecla ceromiaIi.ew. 111. Diur. Lep. p. 185, pL 74. figs. 573, 574 

 (1877). 



Thecla suada Hew. ibid. p. 207, pi. 82. figs. 691, 692 (1878). 



I quite agree with Hewitson that both these names refer to the 

 same insect. The types are more alike than his figures. 



Thecla badaca. 



Thecla badaca Hew. Descr. LycPenidte, p. 12 (1868), J ; 111. 

 Diur. Lep. p. 184, pi. 73. figs. 569, 570 (1877). 



Thecla collucia HeAv. ibid. p. 186, pi. 74. figs. 577, 578(1877), $ . 



An examination of the types leaves no doubt that these names 

 refer to the sexes of the same species. The figures are rather 

 highly coloured, and in that of the female the orange crown to 

 the caudal spot is omitted. 



Thecla opacitas, sp. n. 



Male. Upper side closely allied to T. ceromia Hew., but discal 

 areas of both wings slightly cupreous. Under side much as in 

 T. ceromia ; black anal angular spots on hind wing prominent, and 

 ultramedian band on hind wing more orange and wider. The 

 extreme edge of the costa, as also the collar and the space between 

 the eyes, is cupreous. Palpi black, with a few whitish hairs ; 

 terminal joint black. 



Expanse Yi inch. 



Hah. Mexico : Atoyac, Vera Cruz, in May {H. H. Smith). 



Type, Mus. Godman. 



This insect may prove to be a form of T. ceromia Hew., but at 

 present it appears sufficiently distinct to require a name. 



Thecla canus, sp. n. 



2Iale. Upper side : allied to T. ceromia Jiew., but discal areas of 

 both wings distinctly cupreous. Under side much as in T. ceromia, 

 but ground-colour paler and more olivaceous, and ultramedian 

 band on hind wing pale orange and wider and marginal red spot 

 more lunular and confined between lower median nervules. Palpi 

 pure Avhite, upper side of terminal joint only black. 



Expanse li inch. 



Hah. Mexico : Chilpancingo, Guerrero, 4600 feet, June {H. H. 

 Smith). Amazons : Santarem {Bates). Mus. Godman & Mus. Brit. 



Type, Mus. Godman.
