1. P. mercuriana, iifwZ'. ; monticolana, Wilk. — Ex- 

 panse \ i^^ch (12-14 mm.). Fore wings narrow, pointed, 

 orange brown with bands of dark chocolate, and numerous 

 silvery white streaks. 



Antennae black-brown, barred with white ; palpi grey- 

 brown ; head and thorax red-brown with white-tipped 

 shoulder-lappets ; abdomen black, frosted with white. Fore 

 wings narrow ; costa nearly straight, and very narrowly 

 folded ; apex bluntly angulated and produced, hind margin 

 oblique ; basal blotch red-brown, not reaching the costa, but 

 extending far upon the dorsal margin, its edge oblique ; 

 costal region above it pale buff, this colour extending into a 

 transverse band outside the basal blotch, but edged by 

 several bright white streaks ; central band oblique, dark 

 chocolate red, this colour extending round the anal angle,, 

 and up the hind margin, where it spreads and divides, form- 

 ing two branches, to the apex and costa, and enclosing a 

 white spot ; two more costal white streaks edge a large 

 cloudy orange brown space outside the central band ; cilia 

 white. Hind wings smoky brown, with white cilia. 



Undersides of all the wings leaden brown ; costal dots of 

 fore wings white. 



Rather variable in the depth and brightness of colour of 

 the markings, and found rarely of an almost unicolorous 

 red-brown, with only silvery indications of the white streaks. 



On the wing in July and August. 



Larva cylindrical, of nearly uniform bulk, semi-transparent 

 dirty greyish green with a tinge of yellow on the ventral 

 surface ; head shining, pale brown ; dorsal plate grey with a 

 black hind margin ; anal plate ochreous ; raised dots incon- 

 spicuous. (C. Wood.)

 Wood from heather. Probably it is not very particular as 

 to its food. 



A mountain species, and local. Mr. Stainton, who saw it
