In the Collection of W. C. Hewitson, from Brazil (Espiritu Santo). 



376. Thecla Beon.

Thecla Beon, var. Jeneirica, Felder, Verh. zool.-bot. Ges. xii. p. 474. 



An example of this species in my collection has no blue, as in Cramer's figure, on the anterior 

 wing. If I had not found it necessary to depend very much upon the position and intensity 

 of colour in the many species allied to this which I have figured, I would have placed T. Cecrops 

 and T. Poeas with this. I cannot help thinking that they are one. 



377. Thecla Cecrops.

The position of the blue on this species seems uncertain. In Hubner's figures of Poeas it 

 is at the base of the posterior wing; in Boisduval and Leconte's the blue is near the outer 

 margin.
