324 LEPIDOPTERA. 



parallel white and darker hind-marginal lines ; the hind 

 wings white. Body and legs brownish-white, the front tarsi 

 dull black, barred with white. 



Usually not variable, except a little in the depth of colour 

 of the markings, and of the grey shade of the ground ; but 

 a specimen taken in the New I'^orest by Mr. L. B. I'rout, 

 has the portion of the fore wings between the first and 

 second lines dusted with black scales, and forming a dark 

 central band, against the unusually white outer areas. 



On the wing from July till the beginning of September. 



Lakva nearly three-cjuartevs of an inch long ; head a very 

 little narrower than the second segment, with lobes rounded, 

 and the mandibles rather prominent, highly polished, dark 

 brown ; dorsal plate jshiniug black-brown ; body of nearly 

 uniform width throughout, tapering only at the anal ex- 

 tremity, rounded above but rather flatter on the undersurface ; 

 segments clearly defined, deeply cut ; dingy dark olive- 

 brown ; a dingy blacl< pulsating vessel shows distinctly at 

 the dorsal stripe ; the ventral surface of the same colour 

 as the upper ; skin with rather a tough appearance ; the 

 raised dots polished, large and prominent ; black ; the hairs 

 also black and short. Altogether a very dingy looking 

 creature. (G. T. Porritt.) 



September till June, on Dicraninii .scoparviim, Uypnuiii 

 cuprcssiformc and other mosses growing on stones or on the 

 earth, forming galleries under and through the moss ; active, 

 and very lively if removed from the feeding-tunnel. 



PurA apparently undescribed ; spun up in the moss. 



This species is especially attached to plantations of Scotch, 

 fir ; appearing later in the season than the other woodland 

 species, it suddenly causes these still and solemn ranges of 

 tall bare trunks to be enlivened by the numbers of small 

 moths which flit from every tree at the approach of an 

 intruder, flying to the earth or to aJower part of the same or
