Ptecticus (Sargus) trivittatus, Say.
A species of Ptecticus taken abundantly at Cincinnati by Chas. Dury agrees so well with Say’s Sargus trivittatus that I cannot convince myself that it is anything else. Specimens when first taken agree more closely with Say’s description than the same specimens do after they have been in the cabinet awhile and have become dry. The green color that Say mentions is present in some while others are yellowish or brownish. The broad, dusky band that Say described as appearing on the basal part of each abdominal segment beyond the second is conspicuous, being of greatest extent on the fifth and sixth.
