1T6 HAUSTELLATA. — ^LEPIDOPTERA. 



cles: pupa elongate, enclosed in a slight folUculus amongst leaves, on the 

 ground. 



The name Campsea was proposed by Lamarck in 1818 to desig- 

 nate Geo. margaritaria, and other insects, whose larva possess 12 

 legs only; and as the species above-named forms the type, it is 

 necessary to employ Lamarck's name, the term Metrocampa not 

 being proposed by Latreille till 1825 : the only indigenous species, 

 there being two found in France, may be known by its large size, 

 beautiful greenish pearly hue, and by the hinder margins of all the 

 wings being angulated in the middle ; the other French species is 

 reddish, and the second species of Ellopia light green, therefore 

 the ground colour of the wings is evidently of less importance as a 

 secondary character in distinguishing genera than the outline and 

 the disposition of the markings, but in these instances it must be 

 borne in mind that green is the spectral tint of red.
