This study is the first revision in 35 years of the native Hawaiian sphecid wasps of the genus Ectemnius. The author provides an original key to species, diagnoses, descriptions, distributions, and illustrations along with a compilation of all known biological information for each species.

Heliodinids are tiny, brightly colored dayflying moths. Phylogenetic relationships among genera of Heliodinidae are proposed using parsimony and character compatibility. We describe and illustrate 45 North and Central species (25 newly named) assigned to five genera (two new, two exhumed from synonymy). Larval host plants are recorded for 33 species (14 newly discovered), about 45% of the known fauna; 90% of these are specialists on Caryophyllales, primarliy Nyctaginaceae.

The catalog provides information on the type of material of 75 valid species of the genus Aphytis Howard (Hymenoptera: Aphelinidae) in the collection of the Entomology Research Museum, University of California, Riverside. 7,390 specimens were remounted from Hoyer's medium into Canada balsam, including 309 primary types, 2,473 secondary types, and 4,608 non-type specimens. Lectotypes are designated for 11 species.

The coenosus group, containing 34 species, is the most speciose clade of Histerini in the Americas. The author provides the first comprehensive revision of these species, including keys for identification, complete distributional data, illustrations of diagnostic characters, and a detailed phylogenetic analysis. He uses the phylogeny to examine the evolution of several biological characteristics, with particular emphasis on myrmecophily.

This monograph describes the setting, features, and artifacts recovered from a major San Luis Rey II (prehistoric Luiseno) village in northern San Diego County, California. Even though there are some limitations in the samples, this study provides the basis for comparative analyses of several other regional San Luis Rey II villages and sets the stage for a synthetic discussion of late prehistoric settlements in the San Luis Rey River basin.

The authors revise the genus Anopina of the leafroller family, Tortricidae (Lepidoptera). This genus ranges from southern Canada to Costa Rica, with its greatest species richness in the higher elevations of Mexico. The larvae are suspected to be leaf-litter feeders. Sixty-two species are treated, of which forty-nine are described as new to science. The authors provide a hypothesis of phylogenetic relationships of the species, propose a classification, supply a key to species groups based primarily on features of the genitalia, and include illustrations of adults, larvae, and male and...
