Four species of Cory thalia C.L.Koch 1851 were reported by Richman & Cutler (1978) to occur in North America north of Mexico. Subsequently, one of these four species, C. delicatula Gertsch & Mulaik 1936, was synonymized with Euophrys dim in uta (Banks 1896) (Edwards 1980). Of the three remaining species, only two species can validly be placed in the genus. These are C. conspecta (Peckham & Peckham 1896) and C. opima (Peckham & Peckham 1885), the northernmost species in the genus, both with reported distributions ranging from Central America to Arizona.
Paracoccus marginatus Williams and Granara de Willink, here called the papaya mealybug, was first detected in the United States in Hollywood, Florida in 1998. By the end of 1998 it was found in four localities in the state and has since spread to nine localities in five counties. This mealybug appears to have moved through the Caribbean area since its 1994 detection in the Dominican Republic. The pest is reported to cause serious damage to tropical fruit, especially papaya, and has been detected most frequently, in Florida, on hibiscus. It is now known from Antigua, Belize, the British Virgin Islands, Costa Rica, Guatemala, Mexico, Nevis, Puerto Rico, St. Barthelemy, St. Kitts, St. Martin, and the US Virgin Islands. Hosts include: Acacia sp.(Luguminosae), Acalypha sp.(Euphorbiaceae), Ambrosia cumanensis (Compositae), Annona squamosa (Annonaceae), Carica papaya (Caricaceae), Guazuma ulmifolia (Sterculiaccea), Hibiscus rosa-sinensis (Euphorbiaceae), Hibiscus sp. (Euphorbiaceae), Ipomoea sp. (Convolvulaceae), Manihot chloristica (Euphorbiaceae), Manihot esculenta (Euphorbiaceae), Mimosa pigra (Lugiminosae), Parthenium hysterophorus (Compositae), Persea americana (Lauraceae), Plumeria sp. (Apocynaceae), Sida sp. (Malvaceae), Solanum melongena (Solanaceae). The species is believed to be native to Mexico andlor Central America.

Information is given on the geographic distribution, habitat preferences, larval foods, and immature stages for 57 species of 9 genera of Sciomyzidae known to occur in Alaska. An illustrated key to adults is included. Alaska as a habitat for sciomyzid flies is discussed, and information on feeding habits of the larvae is summarized.
Two new species of Trichapion Wagner, T. baranowskii and T. santaritae, are described from Madera Canyon, near Tucson, Arizona. Six new species of Coelocephalapion Wagner are described: C. dilox (Mexico), C. goldilox (Costa Rica, Panama), C.johnsoni (Panama) with host Vatairea erythrocarpa Ducke (Fabaceae), C. nirostrum (Mexico), C. tellum (Texas, Mexico), and C. turnbowi (Mexico). Apionion opetion is described from Mexico. A closely similar species, Apionion bettyae (Kissinger), new combination, with probable host plant Lonchocarpus sp. (Fabaceae), is transferred from Trichapion.
Seventeen new species of Arpactophilus from New Caledonia are described and figured. These are the first from New Caledonia and bring the number to 37 species of the genus from Australia and nearby islands, all east of Wallace's Line. The new species are abdominalis, arboreus, brochus, caledonicus, concauus, cuspidis, dolichocara,gressitti, irwini, kraussi, nemoralis, nigripes. propodealis, schlingeri, scutellaris, syluaticus, and webbi. All ofthese have an occipital carina, sometimes most evident ventrally. As a rule there are 2 forewing submarginal cells, but in caledonicus, dolichocara, nigripes, and propodealis there is only one such cell.
Therion Curtis (Ichneumonidae: Anomalinae) has a nearly cosmopolitan geographic distribution but has not previously been recorded from South America. In most Therion the tarsal claws are simple or have only a few inconspicuous teeth near the base. The new species described herein are distinctive, therefore, because they have the tarsal claws conspicuously pectinate over at least 0.8 the distance from base to apex. Therion ranti n.sp. from Cordoba and Mendoza Provinces of Argentina may be recognized by its almost uniformly red mesosoma and basally elevated clypeus. In Therion wileyi n.sp., from the Andean puna near La Paz in Bolivia, the mesosoma is red with extensive black coloration, including much of the propodeum, and the clypeus is weakly and symmetrically convex in profile. Therion wileyi n.sp. was reared from an unidentified noctuid moth larva infesting Chenopodium quinoa (Angiospermae: Chenopodiaceae), an importantfood crop in Andean South America.
The Culicoides fauna of Belize is poorly known, and until 197 4 only 3 species were recorded. Nineteen species of Culicoides from Belize were identified from six collection sites: C. barbosai Wirth & Blanton, C. crepuscularis Malloch, C. debilipalpis Lutz, C. diabolic us Hoffman, C. foxi Ortiz, C. furens (Poey), C. gabaldoni Ortiz, C. heliconiae Fox & Hoffman, C. hoffmani Fox, C. imitator Ortiz, C. insignis Lutz, C. jamaicensis Edwards, C. leopoldoi Ortiz, C. limai Barretto, C. paraensis (Goeldi), C. pifanoi Ortiz, C. pusilloides Wirth & Blanton, C. pusillus Lutz, and a new species, C. mckeeveri Brickle & Hagan is described and illustrated.
The Nesticidae are a worldwide family of small, sedentary spiders frequently found in leaf litter, debris, houses, and caves. The genus Gaucelmus is found only in the Americas, primarily in the N eotropics. Nesticus, a Holarctic genus, is well represented in the Appalachian Mountains by obligate cavedwelling species (Gertsch 1984).
A new genus, Sayapion Kissinger (type-species: Apion segnipes Say) is proposed for the 10 members of the Apion segnipes species group of Coelocephalapion Wagner orphaned when Coelocephalapion Wagner was raised to generic level (Kissinger, 1992). The species transferred from Apion to Sayapion as new combinations are as follows: Sayapion aponipes (Kissinger), S. arizonae (Fall), S. basale (Sharp), S. cinereum (Gerstaecker), S. laterale (Sharp), S. paranipes (Kissinger), S. pronipes (Kissinger), S. segnipes (Say), S. sublaterale (Kissinger), and S. terale (Kissinger).
A taxonomic revision of species of the striatella group, including descriptions ofthree new species from Mexico, Nicaragua and Costa Rica is presented. To date we recognize 6 species in this group: Rhagoletis striatella, R. jamaicensis, R. macquartii, R. triangularis n. sp., R. nicaraguensis n. sp., and R. solanophaga n. sp. Information and records about their distribution, known host plants, and morphological relationships among the species are discussed. A key to the species within the group is presented.
The procleticine genus Dendrocoris Bergroth is revised with the descriptions of three new species from the United States, D. nelsoni, Mexico, D. inermis, and Guatemala, D. guatemalensis. A diagnosis is provided for each species with notes on distribution and host plants. Akeyis provided for determination of all fourteen species.
A taxonomic revision of the genus Cryptotermes occurring in the West Indies is given based on recent collections from the Greater Antilles, Lesser Antilles, and the Bahamas. Seventeen indigenous and four nonindigenous species are described from external morphology ofthe soldier. The imago caste is also described for all but one species. The indigenous Cryptotermes comprise twelve new species, including C. aequacornis, C. cryptognathus, C. cylindroceps, C. cymatofrons, C. darlingtonae, C.juliani, C. mangoldi, C. nitens, C.parvifrons,
C. rotundiceps, C. spathifrons, and C. undulans. Five indigenous species are redescribed, including C. cavifrons Banks, C. chasei Scheffrahn, C. hemicyclius Bacchus, C. pyrodomus Bacchus, and C. rhicnocephalus Bacchus. The imagos of C. pyrodomus and C. rhicnocephalus are described for the first time. The four non-indigenous species are redescribed including C. brevis (Walker), C. domesticus (Haviland), C. dudleyi Banks, and C. havilandi (Sj6stedt). A report of C. domesticus in the West Indies could not be confirmed. Distribution maps and a soldier identification key are included for all Cryptotermes in the West Indies and Florida.
Acmaeodera pubiventris Horn (Coleoptera: Buprestidae) : a polytypic species or a superspecies?
(1999)
Acmaeodera pubiventris Horn was studied in detail and, without rejecting that it may be a superspecies, I concluded it is a polytypic species comprised of A. p. pubiventris, A. p. lanata Horn, A. p. yumae Knull-these generally have been considered as full species-and a new subspecies, A. p. panocheae, described herein. It is suggested that A. p. yumae could be a megasubspecies. Detailed comparisons are made, variation is discussed, and biological and distributional data are provided. A. p. lanata is recorded from Mexico (Baja California) for the first time.
The pink hibiscus mealybug, Maconellicoccus hirsutus (Green), has spread rapidly in the tropical and subtropical areas of the New World especially throughout the Caribbean Islands, and has rece~t1y been discovered in California, Mexico, and Belize. All instal's of the pink hibiscus mealybug are descrIbed and illustrated to facilitate discovery of infestations. Comparisons with other common pest species are provided for most of the 8 instars, and a table is included that distinguishes the pink hibiscus mealybug from other pest species in the field.
