Pcrrhyhns, Hlibn. ; Picris and Eronia (part) aiict. 



The type of Picris, Schrank, was Parnassius Apollo, that 

 of Latreille and Godart was Hcbomoia Lcucipijc, but since 

 we ought to have a genus Picris in tlie Picrimc, I adopt 

 that of Boisduval, the type of which is a white butterfly 

 from Tropical America and unfortunately not congeneric 

 with the white European species. 



GENUS 31. APPIAS. Hubncr.

 Catophaga, Hiibn. ; Tachijris, AVallace. 



GENUS 32. PHRISSUEA. Butler. 

 At once distinguishable from Appias by the rounded 

 form of the wings and different form of the disco-cellulars 

 of frontwings. 



GENUS 33. DAPTONOURA. ButJcr. 



Cat. Eabr. Diurn. Lepid., p. 209 (1869). 



Some of the species of this genus bear a general resem- 

 blance to males of Appias, as for instance D. Isanclra to 

 A. Drusilla, $, the position of the upper disco-cellular of the 

 frontwings however will at once separate them. 



GENUS 34. BELENOIS. Hnhnrr. 



Verz. bek. Schmett. p. 92 (1816). 

 AnnajjJicvis, Hiibn. ; Pinacoptcnjx, Wllgr.
