1 86 LEPIDOPTERA. 



Genus G. LOPHODERUS. 



Antennas thick ; palpi small, slender ; thorax llatly tufted 

 at the back ; fore wings without the costal fold, the nervures 

 beneath smooth ; hind wings heavily ciliated on the front 

 margin. 



We have three species, readily recognised. 



A. Fore wings tawny-yellow, dusted with rust-red. 



L. ministrana. 



B. Fore wings white, with rich brown bars. L. ciactana. 



C. Fore wings red-brown, with silvery-white bars. 



L. politana. 



1. Li. ministrana, Linn. — Expanse ^ inch. (18 mm.). 

 Fore wings tawny yellow, dusted and blotched with rust-red. 



Antenna, palpi, and head of the male dark brown ; thorax 

 red-brown; abdomen pale grey. Fore wings somewhat 

 ovate ; costa fully arched but not folded ; apex blunt ; 

 colour tawny yellow or ashy yellow ; from the base to beyond 

 the middle three-fourths of the width from the dorsal margin 

 is richly clouded with red dusting, which at the outside edge 

 of this takes the form of a deeper dorsal cloud ; all this 

 area bordered by a glistening clouding of silvery scales ; 

 apex and hind margin filled up by a similar red cloud of 

 dusting and having in the middle a small point projecting 

 inwards ; cilia rust-red. Hind wings pale smoky brown ; 

 cilia dusky white. Female similar, or with the red dusting 

 paler or more suffused. 



Underside of the fore wings smoky black, the margins 

 tinged with yellow, the cilia red; hind wings yellowish- 

 white. 



Variable in the degree and extent of the red dusting ; in 

 the North and the Midlands, especially in hill districts, this 

 is increased until in many specimens the yellow colouring is 

 obscured or obliterated, the whole fore wings becoming rust- 

 red or red-brown interspersed with irregular silvery shades.
