 A total of seven species of the tribe Nolini, belonging to the subfamily Nolinae of Noctuidae from Northeast China are recorded in Northeast China to date: Meganola fumosa (Butler, 1879), M. subgigas Inoue, 1982, M. gigas (Butler, 1884), M.albula (Denis & Schiffermüller, 1775), M. liaoningensis Li & Han, 2008, Evonima mandschuriana (Oberthür, 1880) and Nola aerugula (Hübner, 1793) (Fang, 1982; Hua, 2005; Li & Han, 2008). In neighbouring areas, 33 species of 6 genera were distributed in the Siberian region from Russia (Kononenko, 2010), 21 species of 3 genera in the Russia Far East (Tshistjakov, 2008); 33 species of 5 genera in the Korean Peninsula (Kononenko & Han, 2007); 40 species of 4 genera in Japan (Inoue et al., 1982; Inoue, 2001; Yazaki, 1995).

 In this study, three species, Meganola bryophilalis (Staudinger, 1887), M. costalis (Staudinger, 1887) and M. strigulosa (Staudinger, 1887) are reported for the first time from China. External morphology including adults and genitalia are examined and illustrated. Material examined herein are deposited in the Northeast Forestry University (NEFU), Harbin, Heilongjiang, China.

 Adult. Head rather small, labial palpus short and smooth curved at 2^nd segment; antenna extend to about two-third of forewing length. Forewing usually with smooth round apex; median line broad, districted at costal margin; with radial sector branching of R2, R3, R4 and R5; hindwing usually with M3 and Cu1 stalked.

 Male genitalia. Uncus strong; valva broad and thick; succulus thick, long, process of sacculus well developed, and incurved; aedeagus straight, vesica small and simple.

 Female genitalia. Apophysis anterioris shorter than apophysis posterioris; ductus boursae curved or lump; corpus oval, with large and sclerotized signa, patch or taper shaped.

About 60 species were including to this genus in the Palaearctic region (Fibiger et. al., 2009; Poole, 1989), about 130 species in the Oriental region (Lászlót et al., 2010; Poole, 1989).
