wings of the male are smoky-black : of the 

 female, smoky-gray. In both sexes there are 

 two transverse zigzag lines, both of which 

 commence at the costal margin of the wiug 

 the first at one-third, the second at two-thirds 

 of the distance between the base and tip. 

 These lines are most distant at the costal 

 margin, and gradually approach to the inner 

 margin- The part of the wing included be- 

 tween these two lines is darker than the parts 

 outside of them ; but not so dark as a patch 

 at the base of the wing. There is a row of 

 seven black streaks on the hind margin of the 

 wing, just within the fringe : these are very 

 conspicuous in the female, but not so distinct 

 in the male : the hind wings in the male are 

 of uniform colour, but have the same marginal 

 row of black streaks on the hind margin. 

 The hind wings of the female are gray, with a 

 light narrow, zigzag band across the middle, 

 and a light broad band along the hind margin. 

 The head, thorax, and body are quite black, 

 and very hairy. 



The MOTH appears on the wing in July, and 

 was taken in the Highlands of Scotland by 

 the late Mr. Wrenn and the late Mr. Foxcrof t. 

 I am not aware of its having been seen in 

 England, Wales, or Ireland. (The scientific 

 name is Psodos trepidaria.) 



149. The Dusky Carpet (Mniophila cineraria). 



149. THE DUSKY CARPET. The antennae 

 of the male are ciliated, those of the female 

 simple : the fore wings are gray, with three 

 transverse darker waved lines : the first and 

 third are very decidedly marked, and very 

 distinct ; the middle one is paler, and very 

 obscure ; the hind margin of the wing is 

 bordered with a zigzag dark line, and the 

 fringe is slightly spotted : the hind wings are 

 paler than the fore wings, and have an indis- 

 tinct transverse line, and a distinct marginal 



line like that of the fore wings : the head, 

 thorax, and body are gray. 



It is said that a specimen was once taken 

 at Tenby, in South Wales, but I have never 

 seen it. (The scientific name is Mniophila 

 cineraria.) 



150. The Waved Black (Boletolia fuliginaria). 



150. THE WAVED BLACK. The antennae 

 are pectinated in the male, simple in the 

 female : all the wings dark smoky-brown, the 

 basal half darker than the outer half, and 

 bordered by a slight, black, zigzag line : this 

 darker portion of the wing has an indistinct, 

 crescent-shaped black mark near the middle; 

 beyond this darker part of the wing is a broad 

 paler band which, on the fore wings, ends in 

 a pale blotch, near the inner margin : the 

 head, thorax, and body gray. 



The MOTH appears on the wing in June ; 

 three or four have been taken in kitchens and 

 coal cellars in London and one at Worcester. 

 (The scientific name is Boletobia fuliginaria.) 



151. The Grass Emerald (Pseudoterpna cytisaria). 



151. THE GRASS EMERALD. The fore 

 wings are gray- green, with two indistinct 

 tranverse darker lines, the first nearly straiylit, 

 the second zigzag : these two lines are widely 

 separated at the costal margin, and very near 

 the inner margin. Between these is an indis- 

 tinct, crescent-shaped spot of the same colour ; 

 and beyond them is a third line, also zigzag 

 and almost white : the hind wings are paler 

 than the fore wings, and have the white line 

 less distinctly marked : the hea<l, thorax, and
