PAPILIO. 213 



situated close to the submedian nervure. This tuft is more or less developed in the 

 other species, and differs in colour. The median nervure of the secondaries is much 

 elongated, so as to form a tail, which is not spatulate, but slightly tapering to its 

 rounded end. 



The base of the foliate appendage of the fore tibia is placed a little beyond the middle 

 of that joint. 



The harpes of the species of this group vary considerably in structure ; but there is 

 a certain resemblance in those of the different sections as arranged below. Thus, in 

 P. penthesilaus and P. protesilaus the lower edge of the harpe in each has a prominent 

 horn-like process, but the projection above it terminates in a serrate edge in P. penthe- 

 silaus (Tab. LXVIII. fig. 7), and in a blunt point in P. protesilaus (fig. 6). The 

 central longitudinal serrate-edged ridge is much more developed in the latter than 

 in the former. 



None of the other species placed in this group have the same arrangement. This 

 will be best seen on comparing the figures. 



All the species of this group are strictly Neotropical, several of them having a wide 

 range in South America.

secondaries.

Taking Clerck's figure as typical of P. protesilaus of Linnseus, as suggested by 

 Dr. Aurivillius 7 , this name becomes associated with the form of this Papilio in which
