the lunules at the base of the tail are white and the outer margin but slightly serrated. 

 As thus restricted, some variation is to be traced in individuals from various parts of its 

 wide range, but we do not think it desirable to admit any further subdivision, or indeed 

 to recognize the Panama individuals described by Mr. Bates as Papilio glaucolaus 9 . 

 The grounds upon which the latter was separated are stated to be the greenish- 

 white tint of the ground-colour of the wings both above and beneath, the narrower 

 transparent space between the apical border of the primaries, and the straightness 

 of the inner edge of the black outer border of the secondaries enclosing the pale 

 lunules. With the large series now before us these characters can hardly be 

 maintained as definite ; the wings, it is true, have the faintest green tinge pervading 

 them, but this is all. 



We have not as yet traced P. protesilaus beyond the line of the Panama Railway. 

 In the rest of our country, up to Southern Mexico, P. penthesilaus is the prevailing and 

 only form.

We use this name for this form of P. protesilaus the specific distinctness of which 

 seems to be assured by the slight difference in the structure of the harpes of the males. 

 It was applied by Felder to a specimen obtained by Salle in Southern Mexico, probably 

 from the neighbourhood of Cordova, where he so long resided. W T e have an example 

 from Atoyac, in the same district, which agrees closely with Felder's description and 

 figure, so that our determination of this species can hardly be questioned. Making 

 some allowance for individual variation, we find this form prevalent throughout our 

 region and extending beyond it into Colombia. Except at Panama, it is the only
