2O4 BUTTERFLY. 



and is distinguished by the edges of the wings 

 being scolloped or indented: it is subdivided into 

 the Nymphales gemma ti, in which eye-shaped spots 

 are seen either on all the wings, or on the upper 

 or lower pair only, and into the Nymphates phale- 

 rati, in which no ocellated spots are visible on the 

 wings, but, in general, a great variety of colours. 



The fifth section contains the Plebeii. These 

 are, in general, smaller than the preceding kinds of 

 Butterflies, and are subdivided into Plebeii urbicolce^ 

 or those in .which the wings are marked by semi- 

 transparent spots, and Plebeii rurales, in which 

 the spots or patches have no transparency. 



The above distribution of the genus Papilio is 

 not entirely accurate, and must therefore be re- 

 ceived with a proper degree of allowance for a 

 task so seemingly trifling, yet so really difficult. 

 It has been observed by some critics that the 

 blood-coloured spots, mentioned by LinnaBus as 

 characteristic of the Trojans, are not always found; 

 and that the interior angle of the wings in the 

 Achivi is not always marked with an eye-shaped 

 spot: that the surest method therefore is, to con- 

 sider such of the Equites as are of dark or mourn- 

 ing colours as belonging to the Troes, and those 

 of gayer or livelier ones to the Achivi. It is added, 

 that the under wings in some of the Heticonii are 

 slightly indented, and might perhaps as well have 

 been referred to the Nymphales phalcrati; that the 

 under wings of the Danai j'estivi are also often 

 indented ; and lastly, that the family of the Plebeii 

 is particularly inaccurate, many of those insects
