be distinguished by the large cellular brand of the male. On the underside the white 

 edgings to the inner common band are very broad towards the costa in both wings, the 

 outer band too has its inner white border much expanded towards the anal angle. 

 This character serves to distinguish the female from that sex of T. orcynia, which it 

 otherwise much resembles. The specimen of T. Jceila from which Hewitson took his 

 description was captured by us in the valley of the Polochic, from which district we 

 have since received several female examples and other males from San Geronimo ; we 

 have also a male from Southern Mexico in which the blue of the upper surface is 

 rather dark and the wings a trifle less pointed. We have likewise a male from 

 Venezuela agreeing with the type, and we have no doubt that the species described 

 by Hewitson from Nicaragua as Thecia parasia belongs to this species. Hewitson's 

 figures of this insect are very unsatisfactory, the peculiarities of the cellular brand 

 being very inadequately rendered. Our figures represent a male from San Geronimo 

 and a female from the valley of the Polochic.

We have only a single specimen of this species, and it unfortunately is somewhat 

 stained. There is nothing that we are acquainted with that resembles it at all closely.
