GEOMETERS.

rings 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 wing 

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

 )f the distance between the base and tip. 

 ?hese lines are most distant at the costal 

 largin, and gradually approach to the inner 

 largin. The part of the wing included be- 

 reen 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 3TOTH appears on the wing in July, and 

 was taken in the Highlands of Scotland by the 

 late Mr. Wrenn and the late Mr. Foxcroft. 

 I am not aware of its having been seen in Eng- 

 land, "Wales, or Ireland. (The scientific name 

 is I'sodox trcpid(iria.\ 



149. The Dusky Carpet (-Uttiop/tila 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 cine- 

 raria. 



150. The Waved Black (Baleto6ia fuliginaria), 



150. THE WAVED BLACK. The antennas 

 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 Boletolia fidiginaria.} 



151. The Grass Emerald (Ptevdoterpna cylisaria). 



151. THE GRASS EMERALD. The fore wings 

 are gray-green, with two indistinct transverse 

 darker lines, the first nearly straight, 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 head, thorax, and
