been divided by subordinate characters of neuration and 

 structure. Thus, the following genus differs from the others 

 in having all the branches of the sub-costal nervure emitted 

 from the end of the cell. 



GENUS ZEONIA.

pi. in (1833); Westvv. Gen. Diurn. Lepid. p. 431 (1851);

The species of this genus may be recognised at once by the 

 transparent wings with black borders and the transverse stripe, 

 which, on the hind-wings, occasionally coalesces with the 

 border, and is sometimes separated from it. The long hind- 

 wings, of which the lower part is black, striped in the middle, 

 or bordered below with bright red or orange, and throwing 

 off a long narrow black tail from the outer angle, are charac- 

 acteristic. There is generally a shorter tail also (sometimes 

 reduced to a mere projection) nearer the anal angle. The 

 species, which inhabit various parts of South America, are not 

 numerous, and one only (Z. bogota, Saunders) is known to 

 extend to Central America, where it was found by Mr. 

 Champion frequenting sunny openings in the forest. 



On- account of the shape and general colour of this genus, 

 the late Mr. Wilson Saunders has not inaptly compared 

 it to the East Indian genus Leptotircus, which belongs to 

 the Equitidce. 

 The type is
