New Cantharidae (Coleoptera) from the Dominican Republic and Haiti. - The material dealt with in this paper was sent for identification by Dr. M.C. Thomas from the Florida State Collection of Arthropods (FSCA). The following species new to science are described: Tylocerus basitestaceus; Silisdiscodon thomasi, S. lavegaensis; Silis superba; Tytthonyx s.str. coriaceipennis, T. s.str. barahonaensis, T. s.str. larimarensis. All holotypes and some paratypes are deposited in the above mentioned collection.
Acmaeodera tiquilia Westcott and Barr, new species, from Big Bend National Park, Texas is described, figured, and discussed in considerable detail, particularly in relation to the similar and partially sympatric A. recticollis Fall. A neotype is designated for A. quatuordecimspilota Obenberger and that species is synonymized with A. ornata (Fabricius). Additionally, A. gibbula gila Knull is synonymized with A. gibbula LeConte; A. nautica Van Dyke is synonymized with A. simulata Van Dyke.
Taxonomy, synonymy, distribution, and biologies of Nearctic (and a few Neotropical and Pale arctic) Anthribidae are reviewed, new keys are provided, and four new genera and eleven new species are described. Allandrus Leconte, 1876 (=Tropiderinus Reitter, 1916). Anthribus Geoffrey, 1762 (=Pseudobrachytarsus Pierce, 1930). Araecerus Schoenherr, 1823 (=Araeocorynus Jekel, 1855); Araecerus coffeae Fabricius, 1801 (=Tropideres (Rhaphitropis) mateui Cobos, 1954).

Choragus major n. sp., Ohio, etc., striolatus n. sp., Ohio, and exophthalmus n. sp., Virginia. Corrhecerus Schoenherr, 1826 (=Paranthribus Jordan, 1904) resulting in Corrhecerus rufescens (Jordan, 1904), new combination. Eurymycter Leconte, 1876, and Gonotropis Leconte, 1876, are removed from synonymy with Tropideres Schoenherr, 1823, and returned to full generic rank. Eusphyrus Leconte, 1876 is removed from synonymy with Ormiscus Waterhouse, 1845, and returned to full generic rank; Tropideres (Opisthotropis) vasconicus Hoffmann and Tempere, 1954, from France is transferred to Eusphyrus, with Opisthotropis a generic synonym; Eusphyrus pulicarius Boheman, 1859, Brasil, is transferred from Brachytarsus, and the species eusphyroides Schaeffer and quercus Schaeffer are transferred from Ormiscus. Gymnognathus triangularis n. sp., Texas. Habroxenus n. gen., type species H. politus n. sp., Texas and Maryland, also H. fuscus n. sp., Guatemala, and H. sarmenticola n. sp., Haiti. Neoxenus n. gen., type species N. versicolor n. sp., Texas, etc.; congeneric: Notioxenus ater and polius Jordan, 1907, Central America, andpallipes Suffrian, 1870, Cuba. Phoenicobiella trituberculata (Suffrian, 1870, Cuba) transferred from Toxonotus Lacordaire, 1866. Piesocorynus lateralis Jordan, 1906 (=P. virginicus Leng, 1918). Sicanthus n. gen., type species S. rhizophorae n. sp., Florida. Toxonotus bipunctatus Schaeffer, 1904 (=Neanthribus obtusus Jordan, 1906); Toxonotus penicellatus Schaeffer, 1906 (=Neanthribus segregus Jordan, 1906); Toxonotus vagus Horn, 1894 (=Neanthribus hieronymus Jordan, 1906). Trigonorhinus lepidus n. sp., California; Trigonorhinus limbatus Say, 1827 (=Brachytarsus plumbeus and B. vestitus Leconte, 1876, and Brachytarsoides minor, quadratus, quadratus ssp. nigrinus and rufodorsalis Dethlefsen, 1954); Trigonorhinus grise us Leconte, 1876 (=Brachytarsus riddelliae Schaeffer, 1906, and Brachytarsoides cylindratus, elongatus, nevadensis, nevadensis ssp. tigrinus, and vulgaris Dethlefsen, 1954); Trigonorhinus tomentosus Say, 1827 (=Brachytarsus paululus Casey, 1884, B. beyeri Schaeffer, 1906, B. franseria Barrett, 1931, and B. irregularis Tanner, 1934); Trigonorhinus zeae Wolfrum, 1931 (=Opanthribus trimaculatus Senoh, 1986); Trigonorhinus areolatus Boheman, 1845 (=Tropideres (Tropideres), bagueni Cobos, 1954, Spain). Introgressive hybridization is invoked for the Trigonorhinus limbatus-griseus complex. New keys are provided for the species of Brachycorynus, Choragus, Habroxenus, Neoxenus, Phoenicobiella, Trigonorhinus, and Eusphyrus, plus a new key to Nearctic tribes and genera, and a new Nearctic checklist. New distribution and life-history data are given for many species.
The following 10 new species of biting midges are described and illustrated from Dominican amber: Culicoides (Oecacta) antilleanus, C. (0.) brodzinskyi, C. (0.) ambericus, C. (0.) hispanicolus, C. mammalicolus, Brachypogon (B.) american us, B. (Isohelea) dominicanus, B. (Isohelea) prominuloides, Stilobezzia (S.) antilleana and S. (Acanthohelea) dominicana. Two other species, in Nannohelea and Stilobezzia, are described but not named. Stilobezzia (Acanthohelea) wirthicola is a new name for Stilobezzia (A.) succinea Szadziewski from Miocene Saxonian amber, which is preoccupied by the extant Stilobezzia succinea Ingram and Macfie, from Argentina.
Larvae of the three common North American species of Phylocentropus (Trichoptera: Dipseudopsidae)
(1998)
The caddisfly genus Phylocentropus includes 7 extant species globally, of which 5 occur in eastern North America and 2 in eastern Asia. Larvae of the 3 most common North American species [Phylocentropus carolinus Carpenter, P. lucidus (Hagen), and P. placidus (Banks)] were associated with identifiable adults and diagnostic characters are described. Larvae ofthese 3 species may be distinguished by overall length of mature larvae, head color pattern, and number of spines on the hind tibiae. Larvae of other species of this genus are unknown.
This revision of the Neotropical predaceous midges of the genus Brachypogon (Brachypogon) Kieffer, recognizes 18 extant species, including the following 12 new species: Brachypogon (B.) apunctipennis, bifidus, bimaculatus, ecuadorensis, ethelae, insularis, monicae, pseudoparaensis, schmitzi, spatuliformis, telesfordi, and woodruffi. Two species groups are recognized, the fuscivenosus and impar groups. The hitherto unknown male of B. paraensis Wirth & Blanton is described and illustrated, and the female of that species as well as both sexes of B. impar (Johannsen) and B. fuscivenosus (Lutz) are redescribed and illustrated. Diagnoses are provided for previously described species, as well as a key for the recognition of all Neotropical species. New records of B. impar are from Brazil, Colombia, and Argentina.
A new tribe is established in the Limnichidae, Limnichinae, for a new genus and species, Wooldridge us perforatus, from Sabah, Malaysia. Two autapomorphic characters distinguish Wooldridgeini from the two other tribes ofthe subfamily Limnichinae; 1) the mesotarsus and metatarsus join their respective tibia ventrally (medially) and preapically instead of the usual apical only connection and 2) a large pore, presumed to be an opening of a prothoracic gland, is present on each hypomeron. Distinguishing characters are illustrated by scanning electron micrographs and line drawings. A key to the three tribes included in the Limnichinae is provided.
Afralampes capensis is described as a new genus and species in the Megalonotini. The systematic position of Serranegra Lindberg is discussed, a new species is described from South Africa and a key to species included. A new species of Diniella Bergroth is described from South Africa and a key to the African species included. A new species of Polycrates Stal is described from South Africa. The immature stages of Polycrates consutus (Germar) are described with notes on its distribution and biology. The first records of the occurrence of species of Lampropunctus Scudder and Lamproceps Reuter from South Africa are included. Wing polymorphism is discussed. Lispolophus Bergroth is reduced to junior synonymy with Diniella. Diniella nitens (Wagner) is reduced to a junior synonym of Diniella laevicollis.

Se describen ademas seis nuevas especies: Cubobolus potrerillo, C. escambray, C. dentatus, C.jibacoa, C. monitongo, y C. cuba. Se comenta la exclusion, hasta el momento, de representantes del genero Anadenobolus en la isla de Cuba.
