Aedes (Banksinella) imprimens (Walker) has been the species only incompletely described; so far, no figures have been given. The author recently identified a mosquito species collected near Sendai to be this species. A great many specimens have been collected since several years ago. The morphological description on adults and pupae of this species is given in this paper. Male and female heads differs in their scaling (fig.1). Male palpi long, uptured, hairly, and composed of a long basal segment, the second segment of moderate length, and a very small apical one (Fig.2). Scutum covered with narrow golden scales. Abdomen black, with white basal bands and lateral spots on each segment. Legs dark brown, with pale basal rings on each segment of tarsi and metatarsi. Male genitalia are very peculiar in its structure (Fig.3). Pupae resemble to those of Aedes esoensis and Ae. vexans, but A-hairs of eighth abdominal segment are 7-8 forked (Fig.4). Their habitat was in temporary ground-pools with decayed leaves.
