Mamestra trifolii, Esp.

Length when full grown 1.10 inches. In shape and appearance very much like the larvæ of Agrotis lubricans. Color uniforn grass green marked as follows : a rather broad substigmatal line of creamy white, having at times a slightly pinkish tinge ; a dorsal line of dark green. There is no trace of a subdorsal line except that the place of that line is a very little lighter on the first three joints when the larva is crawling. Stigmata narrowly edged with black. Head rather small, a little paler than the body. Piliferous spots very small.
