We have selected upwards of 120 specimens of this species to represent its range 

 and variation, and we do not see our way to making in them any specific separation. 

 The types of T. isobeon of Butler and Druce are before us, and these do not differ in 

 any way from many other individuals of the series, nor does the description make any 

 allusion to the points wherein they are supposed to differ. Thecla bactra appears to 

 have been based upon a female example of this species from Nicaragua. Hewitson is 

 silent as to the sex of his type, nor does it seem to have occurred to him that the 

 species he was describing had any relationship to T. beon. In North America two 

 forms of this species occur, both of which differ in the blue patch of the secondaries ; 

 the Florida form, T. hugon of Godart, having scarcely any blue at all on those wings. 

 We have several specimens from Pernambuco, given us by the late W. A. Forbes ; on 

 comparing these with our Guatemalan examples we find no practical difference. In 

 Guatemala T. beon ranges to an altitude of 5000 feet above the sea. 



The specimens figured are from San Geronimo, Guatemala.

Hab. Nicaragua l (mus. Hewitson). 



There is a single male specimen of this species in the Hewitson collection in the 

 British Museum, which we have not been able to associate with Thecla beon and its 

 allies, though it evidently belongs to that section of the genus. Hewitson states that 

 he described a female, but this seems to us an error.
