Anellus extending to middle of phallus. Vinculum broadly sclerotized, capsulate, with a pair of small protrusions on distal margin. Phallus of even width except slightly-swollen at basal 1/6, slightly bifid apically.

Female genitalia (Figs 59-60): Apophyses posteriores 2 × longer than apophyses anteriores. Elongate scales on posteroventral margin of A8. Lamella antevaginalis short, cylindrical, with ridge posterolaterally.

Distribution.

Eastern Canada and the United States west to Texas.

Host plants.

Hickory ( Juglandaceae : Carya ) and linden ( Tiliaceae : possibly Tilia americana L.) ( Forbes 1923). These are from the label data in the USNM collection. The collection also includes a specimen whose label data states that it came from oak ( Fagaceae : Quercus ). The label data give no details other than plant common names. Therefore, it is not clear if these records refer to larval host plants or where the adults were collected.
