1885.] MR. H. DRUCE ON NEW HETEROCERA. 523 



Expanse 2| inches. 



Hab. Ecuador {Buckley). 



This species is most nearly allied to P. cruenta and P. lorzce, but 

 it can at once be distinguished from either of them by the entire 

 absence of the red spots on the primaries, besides which there are 

 many other differences. 



Pericopis, Hiibn. 

 PeRICOPIS IRENE, sp. n. 



Primaries dark brown, slightly yellowish near the base ; a pale 

 yellow band crosses the wing from about the middle of the costal 

 margin to the anal angle, and a submarginal row of minute white 

 spots : secondaries with the basal half pale chrome-yellow, the outer 

 half dark brownish black, crossed from the inner margin near the 

 anal angle to the apex by a band of irregular orange-coloured spots 

 and a submarginal row of white spots. Head and thorax black, spotted 

 with yellow ; abdomen above yellowish brown, with a central black 

 line, on the underside yellow ; legs brown. 



Expanse 3 inches. 



Hab. Paraguay {Bates). 



This species is nearest to P. isse, from which it is at once distin- 

 guished by having only one yellow band crossing the primaries 

 instead of two as in that species, the band nearest the apex being 

 entirely absent, and also by the submarginal row of white spots to 

 both wings. 



Pericopis phyleis, sp. n. 



This species is allied to P. phceba and P. ithrana ; but from both 

 it differs in being without the row of spots near the apex of the 

 primaries, and in the almost entire absence of the submarginal row of 

 spots, one only remaining in the middle of the wing close to the 

 outer margin ; the yellow band at the end of the cell is smaller and 

 paler-coloured, the base of the wing to near the middle is bright 

 orange-red, extending in streaks almost to the yellow band at the 

 end of the cell : the secondaries are dark brown, streaked with bright 

 orange-red from the base to the outer margin. Head and thorax 

 black, spotted with yellow dots ; abdomen reddish brown ; legs black. 



Expanse 3| inches. 



Hah. Ecuador, Sarayacu {Buckley). 



This fine species very closely resembles Heliconius bartletti. Mr. 

 Buckley obtained a fine series of this insect ; all the specimens are 

 before me and do not show any variation.

Primaries and secondaries chrome-yellow, the apical third of the

 on to the yellow ; secondaries broadly bordered vnth black. Head,
