Both sexes of a new genus and species referable to the group Ptilodeutes are represented in specimens taken by Mr. Geo. Norman (No. 52) at St. Catharines, and for which I propose the name Ellida gelida. A male of this species is also in the collection of the Buffalo Society, from New York State. The eyes are naked, ocelli absent, legs rather short and unarmed. The maxillæ are moderate ; labial palpi short, applied to the front, second article shaggily haired, third distinct.
