THECLA. 53 



and are of a darker metallic blue on the upper surface and beneath of rather a more 

 purple tint ; but as we find some variation in both respects in our northern specimens, 

 we are inclined to attribute the difference to the age of the examples and the action 

 of light upon them. Hewitson was evidently confused as to this species, as the insect 

 figured on his plate (xliii. f. 167) as a variety of T. stagira must clearly represent 

 another species. Moreover, an example in Bates's collection marked " T. stagira " by 

 Hewitson cannot possibly belong here. We have therefore considered solely his first 

 figure, with which a specimen in Mr. Bates's collection from the Tapajos river fairly 

 coincides.

Eab. Mexico, Cordova (Mumeli) ; Guatemala, Polochic valley (F. D. G. & 0. 8.). 



Of this species we have but two males from Cordova and a female from Guatemala, 

 which we place with them with some doubt, as the white lines on the unJer surface 

 are somewhat differently situated. If, however, this female does not belonj to this 

 species, it is certainly that of a very close ally. We now figure it and one of the 

 Cordova males.

T. volupia is allied to T. leucophceus of the southern continent, being undistinguishable 

 on the upperside ; but, beneath, the wings (especially the secondaries) are more 

 uniformly grey, and the anal lobe is black without any rufous border. The only 

 specimens we have seen of this species are those obtained by Belt, two of which, both 

 males, are now in our possession, one of which is figured.
