在整理东北地区夜蛾亚科标本时,发现东北地区2新记录种:疆夜蛾(Peridroma saucia(Hbner,1808))和汉地老虎(Agrotis characteristica Alpheraky,1892)。对其外部形态进行了描述,同时还对汉地老虎在国内一直沿用的同物异名进行了更正。
Two species,Peridroma saucia (Hbner,1808) and Agrotis characteristica Alpheraky,1892,were recorded for the first time in Northeast China. The adult characteristics were briefly redescribed,and a junior synonym of A.characteristica,which had been misused in China,was corrected.
