i6 LEPIDOPTERA. 



to greyish ochreous ; the dorsal stripe of a darker tint of the 

 same colour, well defined on each side by the pale ground 

 colour ; next a very broad stripe of pinkish-brown, followed 

 by a narrow stripe of the ground colour, faintly edged below 

 with pinkish-brown ; another narrow stripe of the pale 

 ground colour follows, and then a stripe composed of faint 

 freckles of pale pinkish-brown, beneath which are the black 

 spiracles ; on the sides of the second, third, and fourth 

 segments are rather large, brown, shining spots ; legs pinkish- 

 brown ; prolegs tipped with light brown ; usual raised spots 

 brownish, but only visible through a strong lens. (W. 

 Buckler.) Unfortunately Mr. Buckler's figure was taken 

 in a different stage of the larva, and j)resents no indication 

 of the flesh-coloured stripes ! 



April to the beginning of May — but very probably from 

 the previous autumn — on Air a ccespitosa^ and doubtless other 

 grasses, feeding in the shoots, but apparently not entirely 

 within, since Mr. Buckler found it drawing together the green 

 blades with a little silk. 



Pupa rather stout in proportion, head and thorax rounded ; 

 wing and limb-covers not sculptured, very smooth and glossy, 

 but the antenna covers thickened and prominent, and very 

 faintly cross-ribbed ; dorsal and abdominal segments smooth 

 and glossy, but with a narrow darker line at the edge of 

 each, and a very faint sprinkling of minute pits of sculpture, 

 hardly forming a band, at the anterior edges ; general colour 

 mahogany-brown ; abdominal segments tapering, but the 

 anal segments rather]thick and rounded, almost bulging ; upon 

 it is a very short broad cremaster armed with two widely 

 recurved bristles, darker brown. In a light silken cocoon 

 under grass in the ground. 



The male moth flies with great swiftness and vigour in 

 broad daylight, immediately after sunset on still warm after- 

 noons, the female at the same time sitting on grass blades ; 

 otherwise both hide among grass upon the ground during the
