a species of the Erycinide genus Stalachtis, viz, S. Phcedusa, var. 

 Egaensis, nob.* Var. 2 is a doubtful mimetic analogue of Ithomia 

 lUhiissa of the same locality ; and var. 3 resembles very much, on the 

 wing, Stalachtis Calliope. It must be remarked that the species of 

 Stalachtis are quite as abundant in individuals as the Ithomice, as this 

 fact will probably tend to explain why the Leptalides mimic some- 

 times one and sometimes the other. The remaining varieties seem 

 to be indeterminate in their analogies.

The commonest species of the genus. It is scarcely distinguish- 

 able from Ithomia Eurimedia on the wing. It is remarkable that 

 both species exist in company in Guiana as well as in the Amazon 

 region.

cJ. Very much resembles the same sex of L. Kollari, Lucas, of Rio 

 Janeiro ; the wings, however, are longer and more pointed, the black 

 apical portion of the fore wing has a similar centi-al white spot, but the 

 under surface of the hind wing beneath is pallid-yellow instead of 

 ochreous. 



I took both sexes of this species at Para. 



13. L. Licinia, Cram. 



$ . P. Licinia, Cram. 153 e. f. (1779). 



2 . P. Phronima, Fabr. Ent. Syst. iii. i. 206. 646 (1793). 



S . Fore wing long, narrow, lanceolate ; the black apical part is con- 

 tinued as a narrow marginal line to the hind angle, and is destitute of 

 white spot; the hind margin of the posterior wing has a short black 

 border near the apex. 



I think this is scarcely distinguishable from the preceding species; 

 however, aU the examples taken at Para belong to L. Psamathe, 

 whilst all found on the Upper Amazons are conformable to L. Licinia. 

 The (S has a so much smaller portion of the hind border of the wings 

 black than the § , according to Cramer's figure, that I at first con- 

 sidered it a distinct species under the name of L. Galanthis, as quoted 



* This var. is distinguished by the great breadth of the orange-red belt of the 

 hind wing ; it entirely replaces, on the Upper Amazons, the true P/iadusa of Para. 

 It is perhaps the S. DumUi of Perty, Delectus An. Art. p. 153, t. 30. f. 1.
