Genus MANCIPIUM. 



So close a connexion subsists between this and 

 the preceding genus, that the species have been ge- 

 nerally grouped together under a common generic 

 name. But the structural differences of M. Carda- 

 mines and Daplidice are too considerable to admit 

 of their being associated with the true Pontice, how- 

 ever much they may be allied in habit and general 

 appearance. The principal distinctions consist in 

 the relative proportion of the joints of the palpi, 

 which, in Mancipium, have the terminal joint shorter 

 than either of the two others ; in the rounded form 

 of the tip of the anterior wings ; and in having the 

 under side of the secondary pair variegated — cha- 

 racters sufficient to constitute a subgenus. The 

 chrysalis (at least in M. Cardamwes\ is boat-shapeu 

 being widest in the middle, and narrowing gradually 

 to both ends.
