18/2.] MR. A. G. BUTLER ON THE GENUS P1ERIS. 2/ 



P. cardamines, but apparently did not know what he had done as 

 he began his arrangement of the group in his 'Enc. Me'th ' with 

 another orange-tipped species, P. glaucippe : he certainly was not 

 followed by subsequent authors ; and it would create much confusion 

 to follow him now. I therefore prefer to retain the first section of 

 JJoisduval's Pieris, fixing as its type the P. amathovte of Cramer 

 (see 'Cist. Ent.' p. 49), and for the present rejecting the syno- 

 nymous genus Perrhybris, Hiibner. 



In the preparation of this paper I have been much assisted by 

 proofs of Mr. Kirby's recently published 'Catalogue of Diurnal 

 Lepidoptera,' forwarded to me by the author before the completion 

 of that very useful work ; and it is by his express desire that I so 

 soon supplement a portion of that publication by a revision of this 

 group of Butterflies. 



I recognize fifteen genera as having formed parts of the great 

 genus Puns as employed in Doubleday, Westwood, and Hewitson's 

 'Genera of Diurnal Lepidoptera;' they now contain 341 described 

 species in the following proportions : — 



1 . Prioneris g 



2. Delias 67 



3. Mylothris 14 



4. Hesperocharis 17 



5. Leptophobia ] 5 



6. Pieris 15 



7. Appias gg 



8. Phrissura 2 



9. Daplonura 13 



10. Belenois 43 



1 1 . Pontia 32 



1 2. Metaporia 3 



13. Synch/o'e 3$ 



14. Tutochila , 6

I think it certain that this is not a variety of P. thestylis.
