78 INTRODUCTION. 



" It is an attempt," says Dr. Shaw, " to combine, 

 in some degree, natural and civil history, by attach- 

 ing the memory of some illustrious ancient name to 

 an insect of a particular cast." The first Linnaean 

 division consists of Equites, which are distinguished 

 by the shape of the upper wings ; these are longer,

 perior oblong, the inferior very short. The third 

 division consists of the Danai, so called from the 

 sons and daughters of Danaus. They are divided 

 into Danai candidi, or such as have whitish wings, 

 and Danai festivi, in which the ground colour is

 division consists of the Nymphales, distinguished by 

 the edges of the wings being scolloped or indented ; 

 it is subdivided into N. gemrnati, in which the wings 

 are marked with ocellated spots, and N. Phalerati, 

 without these spots. The fifth division contains 

 the Pleleii. These are commonly smaller than the 

 preceding butterflies, and are subdivided into ru-
