 592 (1877). 



Hewitson's type, althovigh stated by him to be in Mr. Grose 

 Smith's collection, cannot be found there, and is doubtless the 

 specimen labelled " thama " noAv in the Hewitson Collection in 

 the British Museum. The Museum Collection also contains a 

 specimen from Bogota. 



Thecla atuox. 



Theda atrox Butler, Trans. Ent. Soc. 1877, p. 140. 



This insect probably belongs to the group which contains 

 T. thama Hew.

 Guiana QVhitely), and from Cayenne, also from Santarem and 

 Tapajos. We haA^e it also from Cayenne and from Juhety,
