Two species , E. abstr usa sp . nov. and E. evidens sp. nov. , are described as new toscience. Three species , E. melanops ( Hampson) , E. nigripilosa Yoshiyasu and E. thaiensis Yoshiyasu , are reported for the first time from this country. A key to the Chinese species of the genus is given. Photographs of adults and illustrations of the genitalia of the new species are p rovided. Key wor ds Lepidoptera, Crambidae, Nymp hulinae , Eoophyla , new species , China.
