Generic Type Papilio Betulce, SfC. Lin. 



Specific Character.

 fus maculo nigro lunuldque rubra ornat is; lobo anali suprci cerato, 

 subtus nigro.

 bronzed, beneath black. 



The beautiful little Butterflies included byFabricius in this 

 genus, are scattered over all parts of the world, but are most 

 numerous within the tropics, and particularly in South 

 America, for in Brazil alone I collected near 120 species. 

 They are an obvious and very natural family, though the 

 species are as yet but little understood, and not one half of 

 them described. I have observed a singular peculiarity in a 

 great many of these insects, which is, that when they are at 

 rest in the sun, the lower wings are constantly in a quick 

 vibrating motion up and down, as if the insect was rubbmg 

 them together, more particularly where the two lobes (or ob- 

 tuse tails) of the under wings meet, though what purpose this 

 is intended to accomplish remains unknown. 



The upper surface of the wings in the greatest number of 

 the Hair streaks (as they are aptly called by English collec- 

 tors) are of various shades of vivid blue, so that the species 

 can only be ascertained from the under markings, which are 

 usually very striking and delicate : they are all of a small size. 



This is an African species, and both sexes are in the cabinet 

 of my friend Mr. Haworth.
