64 KHOPALOCEKA. 



female from Guatemala taken by ourselves in the Polochic valley. We figure it and 

 the Costa-Rica type. The Chiriqui specimen is a male lent us by Dr. Staudinger ; it 

 is small, but agrees fairly with the type.

123. Thecla proba, sp. n. (Tab. LVI. figg. 1, 2 <? , 3 $ .) 



Alis azureis ; anticis costa et margine externo nigricanti-fuscis ; postieis, costa late, margine externo anguste 

 nigricantibus, margine interno et ciliis albis : subtus cretaceo-albis fere immaculatis ; postieis lobulo anali 

 macula mimita nigra, macula inter ramos medianos nigra, introrsum fulvo marginata, margine ad angulum 

 analem anguste nigro. 



2 alis griseo-fuscis ad basin vix caeruleo tinctis : subtus linea communi discali obsoleta fusca. 



Hob. Panama, Calobre (Arce), Taboga Island (Champion). 



This species appears to come nearest to T. dindymus of Cramer, but maj' readily be 

 distinguished by the greater extension of the blue colouring into the apex of the 

 wings on the upperside, and beneath by the almost entire absence of all markings. 

 Guided apparently by the upper surface of the wings, Hewitson considered the male 

 of this species to be the female of his Thecla zigira, a species presenting many essen- 

 tial points of difference. 



The male figured came from Calobre, the female from Taboga Island.

 rubra, macula nigra, introrsum rubro cincta, inter ramos medianos.

This species has been the source of considerable difficulty, as it is evidently an 

 insect subject to variation both as regards the tint of the blue of the upper surface 

 and the general tone of the under surface of the wings, the latter being browner in 

 some cases and greyer in others. 



Hewitson took his original description of T. orcynia from a specimen in our collection 

 which we have now before us, and he subsequently described his T. aunia from a
