4 LEPIDOPTERA. 



dorsal Hue and the spiracles filled up by two dark stripes of 

 even width, sometimes separated by a very fine pale thread, 

 the upper being dull purplish-pink, pinkish-brown or olive- 

 brown, the lower dull blackish-green or almost dull black ; 

 just on the lower edge of this dark stripe are the black 

 spiracles ; all the undersurface is pale yellow, palest imme- 

 diateh' below the spiracles and having a paler central line ; 

 legs pale yellow, jjrolegs tinged with dull pink or purplish-

May and June, and the second generation in August and 

 September, on (hdium rcrum (yellow bedstraw), but in con-

Pita rather short and stout, the thoracic portion full and 

 much rounded and the wing-covers thickened, glossy, and 

 hardly sculptured ; limb covers also shining and tightly 

 packed ; dorsal and abdominal segments a little less glossy, 

 minutely punctured, the latter rapidly tapering ; anal seg- 

 ment a little thickened behind ; cremaster rather flattened, 

 tapering to a strong spike, finely forked at the apex ; dark 

 red-brown, the abdominal divisions bright light brown. 



In a slight cocoon in the earth. 



The winter is passed in this state. 



The moth sits during the day on a grass stem, or on that of 

 its food plant, close to the ground, almost only frequenting the 

 patches of yellow Galium which occupy the level spaces and 

 sheltered slopes of sea-sandhills. From these resting places 

 it starts up on the approach of a footsteji, and flits sharply
