The slaty colour of the upper surface of this species separates it from several near 

 allies found in the same country, the similar pattern of the underside being very 

 apparent. It appears to be a scarce insect in the northern parts of Central America, 

 as we have only one specimen from Guatemala and one from Nicaragua. In the State 

 of Panama it is more abundant. 



175. Thecla pisis, sp. n. (Tab. LVII. figg. 24, 25 <3 .) 



T. ceratce similis quoad alarum paginam inferiorem, sed multo magis ochraceis, supra saturate purpureo-mgris 

 unicoloribus.

The much darker wings readily separate this species from T. cerata, which it resembles 

 on the underside, though the wings are of a more ochraceous hue. The species 

 most nearly allied to it probably is T. anthora of the Amazons valley, but the wings 

 have a more purple gloss on them, and the underside is less silvery. In British Guiana 

 we find yet another form of this group, of which we have several specimens taken by 

 Mr. Whitely on the Carimang river in the interior of that country ; these we describe 

 below under the name of T. puppius*. The oldest known form of this group is 

 T. vesulus of Cramer, a species with brown upper surface to the wings and with the 

 end of the discal band beneath of the secondaries broken off into a distinct spot which 

 lies nearer the apical angle. 



We figure a Bugaba male of T. pisis.
