LARENTTD.e-EUPITHECIA. 67 



greyish- white ; head and neck-ridge of the same colour ; 

 thorax and abdomen pale grey ; the latter with a series of 

 minute black dots on the dorsal ridge ; anal tuft pointed. 

 Fore wings blunt, not very narrow except at the base ; costa 

 gently arched; apex and hind margin rounded; dorsal 

 margin almost straight ; colour pale brownish-grey ; basal 

 line rather oblique, curved and slender, dull black ; first line 

 almost parallel, faintly duplicated, slender, brown ; beyond 

 it is a triple series of extremely slender rippled, curved, and 

 bent brown lines closely embracing the discal spot, which is 

 an erect black streak ; beyond these three lines is a parallel 

 series of brown dots, closely followed by a slender brown 

 thread which perhaps is the ordinary second line; this is 

 edged outside by a stripe of the ground colour, and this 

 followed by two faintly browner stripes separated by an 

 excessively indented paler subterminal line ; cilia concolorous. 

 Hind wings rather broad, rounded behind ; pale smoky 

 brown, slenderly barred by three pairs of brighter brown, 

 sinuous cloudy lines; central spot obscurely black; cilia 

 pale brown. Female similar. The markings in both sexes, 

 although numerous, are all faint and indistinct. 



Underside of the fore wings glossy pale smoky brown; 

 costa spotted several times with squared smoky black spots ; 

 discal spot faintly black ; beyond it are three equally faint 

 slender smoky transverse stripes. Hind wings dusky white, 

 three times banded with slender brown stripes, and between 

 these with others, very faint ; discal spot a long black cres- 

 cent. Body and legs grey-brown. 



Usually not variable except a little in the depth of the 

 ground colour and the distinctness — or indistinctness — of the 

 markings ; but specimens from the Hebrides are of a more 

 decidedly grey tint. 



On the wing in June and July. 



Larva rather long and slender, tapering considerably 

 toward the head ; ground colour dark green ; dorsal line
