Eastern PieridcB. 355 



A rare species, which I did not myself meet with, and of which 

 I have not seen a specimen.

Piei'is dice, Voll. Mon. Pier. p. 39, pi. 4, f, 7. 



Hab, — New Guinea, Waigiou (Voll.). 



Another closely allied species of this group, not in the English 

 collections. 



35. Thyca ennia, n. sp. (PI. VII. fig. 4, $, $.) 



Male, — Above, white, upper wings with the costa dusky, and a 

 black border at the apex regularly curved within, enclosing two 

 small white spots and terminating in a point at the outer angle ; 

 lower wings with a narrow hind border, not reaching the outer 

 angle. Beneath : a row of five apical spots, the two uppermost of 

 which are largest and yellow, the base of the lower wings yellow- 

 tinged, and the hind border enclosing a line of narrow yellow 

 spots. 



Female. — Above, white, with a much broader dusky border to 

 the anal angle, the base of the uppers dusky, and a band at the 

 end of the cell connecting the costa with the outer border. 

 Beneath, there is a band of six spots near the outer margin of 

 the uppers, the second and third being larger and yellow ; the 

 base of the wings, the anal margin, and several marks between 

 the nervures, are also yellow; the posterior band is much broader, 

 its inner margin straight and just beyond the end of the cell, and 

 has a submarginal row of six horizontal yellow spots. 



Expanse of wings 2| — 2| inches.

This is very near T. dice, which seems intermediate between 

 this and T. gabia. It is curious that all should be found in 

 the same small island. The upper side of T. dice is, according 

 to Vollenhoven's description, like my male, and the under side 

 like my female. 



***** Females very dark, posterior band beneath red, 

 nervures not black or dilated.

Pieris bagoe, Bd. Sp. Gen. p. 461, ^. 

 Male. — Above, white; uppers with the costal margin and apex 

 and a band from the costa to the middle of the outer margin,
