nearly to the inner margin ; on the disc beyond the 

 middle is a conspicuous black spot, and there are fre- 

 quently two or three fainter dark spots along the fold ; 

 the hind-wings are whitish, with a faint greyish streak

 segment spotted with black; it feeds in the stems of 

 Poa aquatica in May. 



The perfect insect appears in June and July, and flies

 dotted with yellow, with yellow subdorsal lines, and with
