“ 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 Linnasan 
division consists of Equites, which are distinguished 
by the shape of the upper wings ; these are longer, 
measured from their posterior angle to their ante- 
rior extremity, than from the same point to the 
base ; the antennas sometimes filiform. The equites 
are denominated Troes or Trojans, distinguished by 
having blood-coloured spots on each side of the 
breast : or Jehivi, Greeks, which are without red 
marks on the breast, of gayer colours, and having 
an eye-shaped spot on the anal angle of the inferior 
wings. The second division consists of Helioonii , 
which are distinguished by having the wings narrow 
and entire, often naked or without scales ; the su- 
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 candtdi, or such as have whitish wings, 
and Danai festivi , in which the ground colour is 
never white, and the surface variegated. The fourth 
division consists of the Nympkales, distinguished by 
the edges of the wings being scolloped or indented ; 
it is subdivided into N. gcmmati , in which the wings 
are marked with ocellated spots, and .V. Phalerati , 
without these spots. The fifth division contains 
the Plebeii. These are commonly smaller than the 
preceding butterflies, and are subdivided into ru-
