Eastern Pieridce. 347 



The bluish patch on the disk of the upper wings is almost ob- 

 solete in some specimens.

 Papilio thisbe, Cr. 233 C. Pieris thisbe, Bd. Sp. Gen. p. 449, $. 



Hab. — China. 



Boisduval has described an Indian female as the male of Cra- 

 mer's species, which I consider distinct from that of India. I 

 have not seen specimens. 



7. Thyca pyramus, Wallace. 



Pieris thisbe, G. R. Gray, Lep. Ins. Nepal, p. 8, t. 7, f. 1. {P. 



thisbe $ , Bd. Sp. Gen. p. 449, is the female.) 



Hab.—N. India (Coll. Wall., B. M.\ 



This differs so much from Cramer's figure that I believe it 

 must form a distinct species. The female has the lower part 

 of the hind wings yellow and a yellow spot within the cell, and 

 beneath, the whole posterior border is yellow, whereas in Cra- 

 mer's figure and Boisduval's description these parts are white or 

 dusky. 



8. Thyca parihenope, n. sp. (PI. VI. fig. 5, 5 a, $ .) 



Male. — Above : form and markings almost exactly as in T. 

 pasilhoe $, but the anal margin is nearly white and the posterior 

 row of spots less distinct. Beneath: upper wings as in T. pasithoe ; 

 lower wings with the red semicircular band of about the same 

 size and form as in T. pasithoe, the markings of the rest of 

 the wing arranged as in T, pyramus, except that the yellow 

 colour is paler and extends much further up the wing, filling 

 two-thirds of the discoidal cell. 



Expanse of wings 2| inches. 



Hab. — Singapore (Coll. Wall.) ; Borneo (B. M.). 



This insect combines the characters of two very distinct Indian 

 species, but in the Bornean specimen in the British Museum one 

 of the yellow patches beyond the cell is partly divided, showing 

 an approach to the pasithoe form. 



9. Thyca ninus, n. sp. (PI. VII. fig. I, ^.) 



Closely allied to T. pyramus, Wall. Male. — Wings broader 



uppers more triangular, the outer margin not concave and pro-
