For several years, as a result of various Insect Faunal Surveys in Nova Scotia, material of an undetermined Epipaschid of the genus Tetralopha has been accumulating in our collection. On a recent visit to Washington I could not match the species with any named material in the United States National Museum; in general appearance it is fairly close to Hulst's unique type of talleolalis but very considerably larger; although of approximately the same size as robustella Zell. it cannot be mistaken for this species on account of the very definitely geminate t. a. line, the paler median space and the clearly cut t. p. line, which latter character would also separate it from militella Zell.

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.

AbstractAlloxysta Förster, 1869 (Hymenoptera: Figitidae) type material of 19 nominal species deposited in the Canadian National Collection of Insects (Ottawa, Ontario, Canada) and the United States National Museum of Natural History (Washington, District of Columbia, United States of America) were studied. Nine species are treated as valid: A. australiae (Ashmead, 1900), A. commensuratus Andrews, 1978, A. japonicus (Ashmead, 1904), A. lachni (Ashmead, 1885), A. longiventris Baker, 1896, A. minuscula Andrews, 1978, A. nothofagi Andrews, 1976, A. vandenboschi Andrews, 1978, and A. xanthopsis (Ashmead, 1896). The following synonymies are established: A. affinis (Baker, 1896) and A. quebeci Andrews, 1978 junior synonyms of A. castanea (Hartig, 1841); A. alaskensis Ashmead, 1902 and A. coniferensis Andrews, 1978 junior synonyms of A. macrophadna (Hartig, 1841); A. bicolor (Baker, 1896) and A. anthracina Andrews, 1978 junior synonyms of A. obscurata (Hartig, 1840); A. dicksoni Andrews, 1978 junior synonym of A. pilipennis (Hartig, 1840); and A. leguminosa (Weld, 1920), A. megourae (Ashmead, 1887), and A. rauchi Andrews, 1978 junior synonyms of A. brevis (Thomson, 1862). The type material of A. schlingeri Andrews, 1978 and A. halli Andrews, 1978 could not be found and we consider them as nomina dubia. Alloxysta vandenboschi Andrews is removed from synonymy with A. obscurata and considered a valid species. Comments on the type material are given. Complete redescriptions and images are presented for the valid species.
