346 LEPIDOPTERA. 



wonderful likeness to the variety remissa of AiJamea 

 gemina. A very similar but darker specimen has been found 

 in Suffolk this summer by the Rev. C. T. Cruttwell. 

 On the wing from the end of June till August. 



Larva stout, cylindrical, the segments plump, moderately 

 well-defined, and puckered on the sides with short wrinkles, 

 the spiracular region forming a puffed ridge along the eleventh 

 and twelfth segments ; prolegs short, thick, placed well 

 beneath the body ; head glossy, bright reddish-brown ; dorsal 

 and anal plates and legs similar; body glossy, glaucous, 

 greenish-grey, some parts along the sides at intervals dark 

 and translucent, displaying a little of the internal anatomy ; 

 dorsal line visible as a pale pink dorsal vessel ; raised dots 

 small, faintly deeper grey, slightly roughened and having 

 each a minute central reddish-brown dot and a fine hair. 



When younger, rather shining flesh-colour, palest on the 

 thoracic segments, clouded with dull purplish-brown with the 

 head, plates, and raised dots shining red-brown. (W. Buckler.) 



September (?) to June, on Poa maritima, P. distans, P. 

 Borreri and other grasses growing in, or at the edges of, salt 

 marshes ; feeding at night ; hiding during the day under 

 stones or rubbish on the ground, just above tide-mark. Mr. 

 Buckler says that it may be found wherever these grasses 

 grow along sea-banks, the margins of tidal rivers, salterns, 

 muddy creeks, and salt-water ditches; also that he found 

 three or four examples by turning over large numbers of 

 stones, with much labour. The larv^ had made their way 

 quite underneath the stones, forming a small chamber among 

 the matted grass. 



Pupa of the usual form, wing, leg and antenna covers 

 roughened with fine sculpture ; front of each abdominal 

 segment also roughened with minute punctures ; cremaster 

 flattened and terminated by two pointed spines ; general 

 colour bright red, becoming in time more purple-brown ;
