Genus PSEUDOPIERIS, Godm. & Salv. 



The species of this genus have the aspect of Pieris and are 

 probably the most ancient of the New-World Dismorphina. 

 They are all very closely related. 



1. Pseudopieris aquatorialis. 



LeptaUs eequatoriah's, Felder, Wieu. ent. Moiiatsclir. v. p. 75 (18G1). 

 LeptaUs penia, Hopffer, Stett. ent. Zeit. 1874, p. 334. 



"Ecuador" [Felder)-, Pucartambo, Peru [Whitehj). c? , 

 B. M. 



cJ, P. peniUf hab. ? Three examples. Ecuador, Coll. 

 Hewitson. 



Our specimen is the wet phase = P. ccquatoriaJis, P. penia 

 is intermediate, and the examples from Ecuador in the 

 Hewitson series (mistaken for P. nehemia by Hewitson) 

 represent the dry phase. 



2. Pseudopieris viridida. 

 LeptaUs viridula, Felder, Wien. ent. Monatsclir. v. p. 75 (18G1). 



" Bogota " {Felder). Pucartambo and Rio Napo : B. M. 

 Quito : coll. Hewitson. 



The wet phase is unknown to me, but the intermediate we 

 have from the Eio Napo and the dry from Pucartambo and 

 (in the Hewitson series) from Quito. 



3. Pseudopieris nehemia. 



Pieris nehemia, Boisduval, Sp. G^n. L6p. i. p. 528 (1836). 

 LeptaUs cyrhin, Doubleday, in Gray's Zool. Misc. p. 76 (1842). 



Mexico, Venezuela, and Rio Grande : B. M. Minas 

 Geraes and Rio Janeiro : coll. Hewitson. 



I have not seen the wet phase, but Doubleday's type from 

 Mexico represents the intermediate, and typical P. nehemia 

 from all our more southern localities the dry. 



Genus MOSCHONEURA, Butler. 



The species of this genus are capital imitations of the 

 species of the Ithomeine genera Scadu and Aeria. 



1. Moschoneura methymna. 

 Pieris methymiia, Godart, Enc. M(5th. ix. p. 1G6 (1819). 

 Rio Janeiro. B. M. and coll. Hewitson.
