Taxonomy of Isoetes L. largely rests on megaspore and microspore wall ornamentation and spore size. These characters have been reevaluated and the range of their variability is described (SEM photographs). Eight species of Isoetes are recognized for northeastern North America: I. macrospora, I. hieroglyphica, I. tuckermanii, I. riparia, I. acadiensis, I. echinospora, I. eatonii, and I. engelmannii. Each species is provided with a revised list of synonyms, description, ecological notes, representative specimens, and distribution maps. A key to species is provided.

AbstractThe subgenus Chrysocharis s. str. in America north of Mexico consists of 18 species. Of these, six are new: Chrysocharis beckeri, subcircularis, bellincus, clarkae, truncatipennis, and levipectus. The name giraulti is proposed for petiolata Girault nec Förster. Key to species, descriptions, host records, and illustrations are included. Relationships of species-groups of North America and Europe are discussed.

AbstractOrthops rubricatus (Fallén), a European species now known to occur in North America, is transferred to the genus Pinalitus Kelton. Pinalitus solivagus (Van Duzee) is reported from British Columbia, and P. utahensis Knight and P. brevirostris Knight are considered to be synonyms of it. Pinalitus rostratus n. sp. is described from Canada and western United States. Pinalitus californicus Knight is transferred to the genus Proba Distant. A key to species is provided.

A new species of parasitic copepod occurring in western North America is described, Ergasilus nerkae n. sp. An emendation of E. turgidus Fraser, 1920 and a redescription of E. auritus Markevich, 1940 are presented. A total of four species resembling E. caeruleus (E. turgidus, E. confusus Bere, 1931, E. auritus, and E. nerkae) have so far been described, and characters to distinguish the species of this group are given.

A key to 38 North American species of Cryptanura is given. 30 species are recorded for Mexico; new data on their distribution are given. 10 new species from Mexico are de¬scribed; the following new synonymy is established: Cryptanura ectypa (Cresson, 1873) = C. vallis Porter, 1977, syn. n.; C. nitidiuscula Cameron, 1886 = C. bicarinata Cushman, 1945, syn. n.

AbstractTwo exotic species of Xyleborus (Coleoptera: Scolytidae) of Asian origin have recently been detected in the United States. Xyleborus pelliculosus Eichhoff has been collected in Pennsylvania and Maryland, and X. atratus Eichhoff from Tennessee, Georgia, Maryland, Virginia, and West Virginia. Descriptions of both species and a revised, illustrated key to members of the genus Xyleborus in eastern North America are presented. An explanation is proposed for the large numbers of recent introductions of exotic ambrosia beetles from eastern Asia into eastern North America.

While making an intensive study of the bark beetles of Western North America, I noticed that two of the species in the genus Carphoborus were new. Since the last key to the species of this genus has been compiled (Swaine, 1918) Dr. Swaine has described five new species which with my two would more than double the number in the genus. I therefore feel that a new key should be made.I am indebted to the Museum of the California Academy of Sciences for the use of its collection of this genus, and to Dr. E. C. Van Dyke of the University of California for his helpful criticisms.

The species of Ceraturgus occurring in the eastern United States and Canada are reviewed. A key to species, descriptions, illustrations of wings and some genitalic features, and distribution maps are presented. Ceraturgus fasciatus is resurrected from synonymy with Ceraturgus cruciatus, and Ceraturgus mabelae is reduced to synonymy with Ceraturgus nigripes (new synonymy). Ceraturgopsis is resurrected, assigned subgeneric rank, and Ceraturgus cornutus is fixed as type species. This work is dedicated to the memory of one of America’s foremost asilidologists, Joseph Wilcox.
