Larva, " Bright green with five yellow lateral (? longitu- 

 dinal) lines. Head reddish." (Lang.) Berge gives it four 

 dorsal lines and one side stripe, which is equally hard to 

 understand. Mr. F. W. Hawes furnishes a more full descrip- 

 tion : " The eggs are laid in August on coarse grasses 

 {Triticum refcns, &c.) inside the sheath of a lower leaf. The 

 larvae are not hatched until the following spring, apparently 

 about April 20th, when the coarse grasses have attained some 

 little growth. The larva at first is of a pale yellow, with 

 black head and dorsal plate. It is then active, but dislikes 

 exposure, and keeps in the middle of a grass blade, reaching 

 out to the side, to eat from the edge, and in some cases spin- 

 ning a thread or two across its back. After the first moult 

 the dorsal plate becomes less distinct, and the body paler and 

 slightly gi-eenish ; after the second moult the dorsal plate 

 disappears, the colour becomes yellowish green, and a green 

 dorsal stripe appears, continued as a brown stripe over the 

 head and face, the rest of the head being now very pale 

 brownish, the sub-dorsal stripes yellowish, the sub-spiracular 

 veiy pale green, the under surface and legs deeper green. 

 At the third moult a singular pair of white scabrous spots 

 appears in the ventral space between the fourth and the last 

 pair of prolegs. These spots are cast with the skin at the 

 fourth moult, but re-appear and continue through the remain- 

 ing larval life, being very noticeable in the full-grown larva. 

 As the larva gi-ows the colours become more decided and the 

 head becomes mottled with brownish, and finally light 

 yellowish, with a small central brown patch, and on each 

 side a brown line. At the same time the bright green colour 

 becomes more yellowish green, the dorsal stripe darker 

 green, and the other lines yellowish. It is fond of creeping 

 up the grass to the top in the evening, and, from the dark 

 lines on the yellowish head, very closely resembles the tips 

 of the grass. It is a slow and deliberate feeder, and moves 

 freely backward, as well as forward, on the grass leaf, but 

 does not roll it up. When full-grown it spins together the
