 shining indigo-blue, greenish on the hind wing. Fore wing : 

 apex and outer margin rather broadly black. Hind wing : costal

Thecla castimonia, sp. n. (Plate XXXIII. fig. 6.) 



Male. Upper side rich purple-blue, much like T. heera Hew., 

 but without any brand on the fore wing and with very narrow 

 black apex and linear black outer margins. A distinct red spot 

 at anal angle. On the under side the ground-colour is paler ; the

Thecla atena. 



Thecla atena Hew. 111. Diur. Lep. p. 92, pis. 37, 38. figs. 93, 101. 



Mr. Godman's collection contains a good series and we have 

 specimens from Espiritu Santo, Brazil. The variety referred to 

 by Hewitson is now in Mr. Godman's collection and is quite an 

 ordinai'3' form. 



Thecla geba.

This species, as stated, is very near to T. atena Hew., the 

 principal difierence being the more extensive band on the posterior 

 wing below. The type, which has been kindly lent to me by 

 Mr. Grose Smith, is, so far as I am aware, unique, and its habitat 

 has not been recorded. 



Thecla melleus, sp. n. (Plate XXXIII. fig. 7.) 



Male. Allied to T. atena Hew., but the blue areas are much 



less brilliant and less extensive, being confined to the basal half 



on the fore wing ; it has also a broad black apex and outer margin 



on the hind wing. The under side is marked as in T. atena. The
