Extract

In attempting to determine specimens of Dicyphus using Blatchley's key (Heterop. East. N. Am. 1926, p. 908) difficulty was encountered and the following key is presented to facilitate the identification of the species occuring in Eastern North America. It has already been demonstrated by Knight (Bull. Brook. Ent. Soc., XXII, 1927, p. 104) that D. notatus Parshley is a synonym of D. vestitus Uhler and that D. gracilentus Parsh. should not be confused with vestitus Uhl.
