BUTTERFLY. 
and is distinguished by the edges of the wino-s 
being scolloped or indented: it is subdivided into 
the Nijmphalcs gemma ti, in which eye-shaped spots 
are seen either on eJl the wings, or on the upper 
or lower pair only, end into the Nymphales phale- 
rati, in which no oceilated spots are visible on the 
wings, but, in genera!, a great variety of colours. 
The fifth section contains the Pleheii. These 
are, in general, smaller tlian the preceding kinds of 
Butterflies, and are subdivided into Plehesi nrhicolee, 
or those in whicli the wings are marked by semi- 
transparent spots, and Plebeil rurales, in which 
the sjiots or patches have no transparency. 
The above distribution of the genus Ikipilio is 
not entirely accurate, and must therefore be re- 
ceived with a ju’oper degree of allowance for a 
task so seemingly trifling, 3'ct so really difficult. 
It has been observed by some critics that the 
blood-coloured s})ots, mentioned by Linnaeus as 
characteristic of the Trojans, are not always found; 
and that the interior angle of the wings in the 
Achh'i is not always marked with an ejm-shaped 
spot: that the surest method therefore is, to con- 
sider such of the Eipiites as are of dark or mourn- 
ing colours as belonging to the Trues, and those 
of ga^^er or livelier ones to the Achivi. It is added, 
that the under wings in some of th.e Ilelkonii are 
.slightly indented, and might perhaps as well have 
been referred to the Npnphales phalerati ; that the 
under wings of the Danai jestlvl are also often 
indented; and lastly, tliat the family of the Pleheii?.
