2i6 LEPIDOPTERA. 



rough with minute tufts of raised scales; hind wings smooth 

 and glossy. 



We have three species : 

 A. Fore wings green. L. literana. 



A-. Fore wings grey-brown or creamy-white. L. hoscana. 

 A'^ Fore wings bluish- white. L. 'invccum. 



1. L. literana, L. — Expanse f to | inch (18-22 mm.). 

 Fore wings bright green, with abundant minute tufts of 

 raised scales in transverse lines. 



Aatennfe simple, leaden-black ; palpi porrected, pale green 

 above, white beneath ; head and thorax rough, green dusted 

 with black ; abdomen slender, pale grey. Fore wings broad, 

 squared behind ; the costa strongly arched, not folded but 

 roughened with projecting scales toward the base ; green 

 abundantly dusted with black, or with white and black, or 

 having among the dusting sharply pointed black streaks 

 along the disk, or others from the costa, or having these 

 black longitudinal streaks sharply defined upon the green 

 colour without dusting, or the black dusting mingled in the 

 middle with rust-red ; cilia green, often dotted with black, 

 Hind wings smoky white, with whiter cilia. Female similar. 



Underside of the fore wings lead-black ; costal cilia irregu- 

 larly spotted with white ; hind marginal cilia white with 

 black dots. Hind wings smoky white ; nervures dusted 

 with lead-colour. 



Very variable, as indicated above, j-et it is difficult to 

 convey an idea of the loveliness of the ornamentation, of 

 frosting of whiter colour, or of the short black marks inter- 

 spersed among the rows of uplifted scales ; all the phases of 

 marking blending one into the other in different specimens ; 

 so that the names that have been bestowed on the different 

 extreme forms lose much of their signification. Occasionally, 

 though, rust-red markings extend almost throughout tlie 

 fore wings, or still more rarely leaden markings take their 

 place ; but the most striking and interesting specioien that
