(Figs. 14–24)
Type locality: Nova Scotia, Canada.
Diagnosis and description by McDunnough, 1949: 672–673; pl. 31 figs. 23– 24 adult; text fig. 17 D male and female genitalia. Redescription by Bolte, 1990: 653–654; figs. 33 map; 123 male; 124 female; 191 a–b male antenna; 202 a–b female antenna; 212 i–j lateral view adult head; 221 c–d pupal terminal segment; 258 genitalia.
Discussion. This species is included so that comparisons can be made to E. nonanticaria described subsequently. Adults (Figs. 14–17), male genitalia (Figs. 18–22), and female genitalia (Figs. 23–24) are illustrated. Not illustrated in the male genitalia are the well-developed hairpencils and dorsoventrally bifid uncus. E. anticaria occurs from eastern Newfoundland across Canada to western British Columbia, south to northern New Mexico and Apache and Coconino counties, Arizona, with adults from mid-May into July. Bolte (1990) placed anticaria and graefi (Hulst) in his revised mutata group, while McDunnough (1949) included anticaria in his undesignated species-group, but associated with graefi.
