of the under surface. This is sometimes supposed to be P. lanassa, 

 Hoisd., but it certainly does not agree with his description. Fel- 

 der's description of his P. perithea ? so exactly agrees with this 

 in almost all points that I cannot keep it separate. 



13. Pieris nurses, n. sp. (PI. VI. fig. 3, ,J .) 



Form of wings and markings of the upper surface exactly like 

 P. nabis in both sexes. Beneath : the apex of the uppers is pale 

 rufous-brown, and the whole smface of the lower wings earthy- 

 brown with an orange tinge ; the apical spots are obsolete, and 

 tlie dusky border of the lower wings is of a deeper colour within, 

 forming a waved submarginal band ; the base of the upper wings 

 is yellow-tinged, and the basal portion of the costa of the lower 

 wings bordered with deep orange. 



Expanse 1-^^ inch. 



Hub. — Moreton Bay, Australia (Coll. Hewits. ^ ; Coll. W. W. 

 Saunders, ? ). 



Very close to P. nabis, but appears to differ constantly in the 

 colour and marking of the under surface, which resembles perimale 

 of Donovan, but the colouring of the upper surface in his figure 

 is so different that it cannot be considered the same species. 



14. Pieris periclea, Felder. 

 Pieris per idea, Felder, Voy. Novara, p. 169. 



Wings more elongate than P. narses, which it much resembles; 

 the outer margin of the uppers concave. 



Male. — Above, white ; ccsta and base dusky, a triangular black 

 apical patch notched in the middle and reaching the outer angle, 

 with a curved row of six small elongate subtriangular white spots ; 

 hind wings with a narrow dusky border, near which the nervures 

 are black, and a faintly indicated dusky band within. Beneath : 

 the apex of the uppers beyond the row of spots, which are less 

 distinct, rusty-ochre ; hind wings entirely earthy-ochre, with a 

 submarginal row of seven diffused round dusky spots not far be- 

 yond the cell. The base of the uppers orange-tinged. 



Expanse l"^ inch. 



A specimen in Mr. Hewitson's Collection agrees exactly above, 

 but beneath the disc of the hind wings is ochre-yellow, the sub-
