As noted below the two North American species described in Syndipnus by workers appear to belong in other genrra. In Europe the gunus is represented by nearly a score of species and has been reviewed in recent years by two writers (1, 2). North American collections contain very few representatives of the genus; after combining the material in the National Collection with that from the United States National Museum, the latter kindly loaned to me by Mr. R. A. Cushman, only thirty-seven specimens are available for study.

The following notes are based on the material in the Canadian National Collection and in the collections of the United States National Museum, the Museum of Comparative Zoology, and the Philadelphia Academy of Natural Sciences.In all of the three American species of Lyperopherus, the flattened side margins of the pronotum are gradually widened posteriorly to include the outer of the basal impressions. All are flightless and have the elytra widest slightly behind the middle.
