Abstract
A large, finely punctate, vittate species having the facies of a giant form of D. griseostriatus (Degeer), and to a lesser degree resembling very large specimens of Hygrotus unguacularis (Crotch). Readily distinguished from the described Nearctic Deronectes by the narrowly separated and nearly parallel metacoxal lines.
