16. T. oceisia section. 



85. Thecla ocrisia. (Tab. Liv. %g. 5, 6 s .) 



Thecla ocrisia, Hew. Descr. Lye. p. 5 ] ; 111. Diurn. Lep. p. 123, t. 48. ff. 235, 236 \ 

 Thecla zora, Hew. 111. Diurn. Lep. p. 134, t. 53. ff. 304, 305 3 . 



Alls purpureo-nigris; anticis in medio plaga sericea, stigmate magno ad cellule finem; posticis medialiter 

 cseruleo atomatis, fascia submarginali coloris ejusdem : subfcus fusco-nigricantibus, linea communi discali 

 fusca, in posticis obsoleta vix obvia, margine externo sordide albo, maculis submarginalibus fuscis ; posticis 

 maculis ochraceis nigro introrsum limbatis ad marginem externum, lobulo anali puncto nigro, altero inter 

 ramos median os. 



$ alis fuscis ; posticis dimidio anali caeruleo lavatis (interdum unicoloribus) : subtus pallidioribus, maculis et 

 lineis omnibus magis obviis quam in mare. 



Eab. Mexico 2 (Beppe), Jalapa (Edge), Cordova (Bumeli) ■ Guatemala, Polochic valley 

 (F. B. G. & 0, S.) ; Nicaragua, Chontales (Belt) ; Costa Eica, Cache (Bogers) ; Panama, 

 Chiriqui, Chitra (Arce).— South Ameeica, Ecuador 12 , Peru, Amazons valley 3 , and Brazil. 



There appear to be two forms of female of this species, in one of which the anal 

 portion of the secondaries is largely suffused with blue, in the other these wings are 

 wholly brown; both occur in the same districts. The brown form was named by 

 Hewitson Thecla zora, but we do not see our way to separate it from T. ocrisia. We 

 have figured a male from Jalapa. 



17. T. thales section. 



86. Thecla thales.

Thecla thalesa, Hew. 111. Diurn. Lep. p. 98, t. 45. f. 200 \ 



Alis purpureo-nigris, linea submarginali communi nitide cyanea; posticis quoque medialiter eodem colore 

 sparsim squamulatis ; anticis stigmate ad cellulae finem : subtus saturate brunneis, anticis lineolis quinque 

 costalibus cretaceo-albis, maculis discalibus caeruleis et posticis eodem colore irregulariter maculatis, linea 

 duplici ad angulum posticarum analem viridi-aurea, lobulo anali nigro. 



$ alis supra omnino brunneis, aliter alis maris similibus. 



Eab. Nicaragua, Chontales (Belt) ; Panama, Volcan de Chiriqui (Champion), Chiriqui 

 (Bible), Lion Hill (M 'Leannan).— South America, Amazons valley 4 to South Brazil. 



Hewitson separated a female of this species from Mr. Bates's collection as T. thalesa, 

 considering it was doubtfully different from T. thales. With this type before us and a 

 considerable series of specimens from widely distant points in its range, we do not see 

 how the distinctness of T. thalesa can be maintained. T. thales is not a common species 

 in our country, but extends as far north as Nicaragua, whence, however, we have only 

 female examples.
