The following subgenera of Apion Herbst are elevated to generic status: Bothryopteron Wagner (type species: Apion grallarium Sharp); Coelocephiilapion Wagner (type species: Apion bryanti Wagner); Coelopterapion Wagner (type species: Apion testaceum Wagner); Fallapion Kissinger (type species: Apien impunctistriatum Smith); and Stenapion Wagner (type Species: Apion constricticolle Sharp). Twelve areas of apionid rostral sulci and carinae are defined and illustrated. Six new species of Coelooephalapien are described: four similar to C. bryanti, (Wagner): Jumentum (panama and Honduras), kektaon (Belize), pelor (Panama), and schema (panama); and two similar to C. spretissimum (Sharp): adhocum (Mexico) and pigrae (Venezuela). C. pilirostre (Wagner), near bryanti, is redescribed from Mexico and Honduras with neotype designation.
Affinities, diagnoses, and descriptions are provided for two new species of Plusiotis: P. spectabilis from an unknown locality in Central America and P. dianae from Veracruz state in Mexico. Plusiotis spectabilis is described from a single female and is the largest species in the genus (41 mm in length).
An undescribed genus and species of flightless longhorned beetle, Apteralcidion lupierrei new genus, new species, in the subfamily Lamiinae, has been collected from giant thistle, Cirsium subcoriaccum, at high elevations in Costa Rica and Panama. This new taxon appears most-closely related to genera in the tribe Acanthocini.
One hundred forty-five species of caddisflies representing 15 families and 46 genera are reported from Oklahoma. Thirty-nine species are new state records. Families having the greatest species richness were Hydroptilidae (44 species), Leptoceridae (31 species), Hydropsychidae (26 species), and Polycentropodidae (13 species).
Book Review: A comprehensive treatment of the ecology of aquatic insects in one place is needed for both students and researchers. Professor Ward is doing this in two volumes. The first volume covers the biology and habitats, as indicated in the subtitle, of the 13 insect orders that are either entirely aquatic at some stage, or those with some members aquatic at some stage. The second volume will be devoted entirely to the feeding ecology of these aquatic species.
Specific Alaskan and Canadian localities are recorded for the chilopod Scolopocryptops sexspinosus (Say) (Cryptopidae), the only indigenous Nearctic scolopendromorph species occurring north of the lower 48 states. It occurs west of the crest of the Coast Range in British Columbia, extending northward to the southernmost islands of Alaska, and is recorded for the first time from eastern Canada, from Niagara Gorge, Ontario. Reports of S. rubiginosus Koch from southern Alaska are based on a misidentification of S. sexspinosus, and records from the north-central United States are too distant from the international border for it to be plausible for Manitoba and western Ontario. This centipede does not occur along the Pacific Coast and is improbable for any other part of Canada.
Vincent Golia, Delray Beach, Florida, collected a single female specimen of the tamarind seed beetle, Caryedon serratus, in an orange grove near Homestead. This is the first record of this bruchid for continental United States although the species is recorded from the Hawaiian Islands, and is often intercepted during port inspections.
New records of the xystodesmid diplopod Stenodesmus tuobitus (Chamberlin) extend its range and those of the family and suborder Chelodesmidea into southwestern New Mexico, west of the Rio Grande. They confirm that it inhabits arid juniper environments at relatively low elevations as well as moist deciduous fir forests at high elevations, thereby lending credence to past records from the former habitat in Lincoln County. Discovery of the milliped in neighboring mountain ranges to the north and west is now likely, with the distant possibility that it may occur in eastern Arizona.
Ommatius fimbriatus and O. subtus are based upon four specimens embedded in Dominican amber from the El Mamey Formation in the Dominican Republic. The amber is from the Lower Oligocene - Upper Eocene, originating between 25 and 40 million years ago. The specimens are the first reported fossils of Ommatius. Both species are described and compared with modern species. Significant characters are illustrated and/or photographed.
A brief account of the present state of weevil taxonomy is followed by a detailed study of certain structures used in their classification, namely the venter, abdominal tergites, sternite 8 of the male, apex of the hind tibia and deciduous mandibular processes. A key to some 50 families and subfamilies of Curculionoidea is followed by a list of family-group taxa. The following changes are made: Brachyceridae, Erirhinidae. Cryptolnryngidae und Raymondionymidae are promoted to family rank from Curculiollidne; Antliarhininae is demoted to a subfamily of Brentidae, and Allocoryninae to a subfamily of Oxycorynidne; Coptonotini is demoted to a tribe of Curculionidue Scolytinae; Carinae, sufam. n. is erected for Car Blackburn (genus incertae sedis) in Belidae; Dinomor'phini is demoted to a tribe of Molytinae and Brachyccropsidinae is revived from synonymy with Dinomorphinae (Curclliionidae); Urachyderini, Eremnini, Otiorhynchini and Sitonini are demoted to tribes of Entiminue; Desmidophorinae is transferred from Brentidae to Brachyccridae, Ocladiini is promoted to a tribe of Desmidophorinae (from Curculionidae-Cryptorhynchinae); Campyloseelini (including Phaenomerina) is transferred from Rhynchophoridae to Curculionidae-Zygopinae; Carphodicticinae is promoted to subfamily rank and transferred from Curculionidae-Scolytinae to Platypodidae; Perieges; Schönherr is transferred from Curculionidae-Thecesterninae to Cryptoiaryngidae and Agriochaeta Pascoe from Cryptorhynchinae to Hyperinae (Curculionidae); Schadlarius Wood and Mecopelmus Blackman are transferred from Coptonotidae to Platypodidae.
