Gyrinids were collected from lotic and lentic sites in the Texas Big Thicket, where species frequently exhibited aggregation. Aggregations consisted of two or more species, and some aggregations had species representing up to three genera: Dineutus MacLeay, Gyretes Brullé and Gyrinus Müller. The composition of these aggregations is described along with habitat preferences. In the Big Thicket region of east Texas, gyrinids are most commonly found in species aggregations and were rarely collected in as single species groups.

Cybocephalus flavocapitis, new species, is described from Taiwan. Morphological features including detailed drawings of the male genitalia are illustrated, and host record and distribution data are provided. Cybocephalus nipponicus Endrödy-Younga is recorded from Taiwan for the first time.

The genus Evides Dejean, 1833 (Coleoptera: Buprestidae) belongs to the family of wood-boring beetles commonly known as jewel beetles. This comparative study was undertaken on the morphological characteristics of three species from field specimens, private collections and collections at the Transvaal Museum of Natural History. The genus Evides consists of eleven species and one subspecies in total worldwide. Nine species and one subspecies are endemic to Sub-Saharan Africa. One species is recorded from India and further species from Laos and Vietnam: Bellamy (World Catalogue, in prep.) The objective of the study was to quantify morphological differences between species representing the genus in South Africa. Specimens of E. gambiensis (Laporte & Gory, 1835), E. interstitialis (Obenberger, 1924) and E. pubiventris (Laporte & Gory, 1835) were collected in the Waterberg (Limpopo Province) and additional specimens of E. pubiventris were collected at Ezemvelo Nature Reserve (Gauteng Province). All three species are related, difficult to differentiate in the field and occur on the same host plants, marula (Sclerocarya birrea (A. Rich.) Hochst.) and false marula (Lannea discolor (Sonder) Engl.). Results indicate that there are morphological differences and species can be differentiated according to elytra length, total elytron width, eye size, frons length, frons width and abdomen length.

The tenebrionid genus Eschatomoxys Blaisdell is revised with descriptions of four new species, E. pholeter, E. paco, E. rosei, and E. andrewsi. Eschatomoxys wagneri Blaisdell, the type species, and E. tanneri Sorenson and Stones, are redescribed with illustrations and a key for the identification of all species. The biology of these rare beetles is discussed with emphasis on the cave dwelling species. The species have metapopulations fragmented among cave and island habitats.

Three new species of the weevil genus Achia Champion are described: A. urvilleae Clark and Burke from the state of Santa Catarina, Brazil and Misiones Province, Argentina; A. uniformis Clark and Burke from Bolivia; and A. boliviana Clark and Burke from Bolivia and Salta and Santiago del Estero provinces, Argentina. Keys and illustrations to facilitate identification of the species are provided. New host plant records for these and other species of Achia include: Urvillea ulmacea Kunth for A. urvilleae; Urvillea chacoensis Hunz. for A. boliviana; Serjania laruotteana Cambess for A. ancile Burke; and Serjania fuscifolia Radlk. for A. affinis Hustache. The genus Achia is apparently most closely related to Cissoanthonomus Hustache and Cionopsis Champion. These three genera have the head constricted behind the eyes, profemora greatly enlarged, and their known hosts are plants of the family Sapindaceae.

The impact of entomology on some of Charles Darwin's thought processes are demonstrated via direct quotations concerning leaf beetles (Coleoptera: Chrysomelidae) made by Darwin in his well documented correspondence from 1821 to 1967. Some aspects of chrysomelid natural history, especially the use of genitalia to separate species, contributed to his theories on speciation, sexual selection, and biogeography.

One new genus and two new species are described from central West Africa: Camerunadora bifasciata, new genus & new species from the Republic of Cameroon and Holubia gabonica, new species from Gabon are described and illustrated.

The ability of Hylaeogena thoracica Waterhouse, 1889 (Coleoptera: Buprestidae) to induce galls on Amphilophium paniculatum (L.) H.B.K (Bignoniaceae) is reported here. Species of Hylaeogena Obenberger, 1923 are associated with vines of the family Bignoniaceae as leafminers, therefore this report represents the first record of the genus acting as a gall inducer. The effect of the inquiline Philides anthonomoides Champion, 1906 (Coleoptera: Curculionidae, Conoderinae) on gall morphology is also described. Most Neotropical conoderines are associated with tree falls and are assumed to be wood-borers. This represents the first report of the species acting as an inquiline in galls. Four parasitoid species belonging to three families of Hymenoptera that emerged from the galls are also reported.

A new genus and species of flea beetle, Yaminia gmelini Prathapan and Konstantinov, from southern India, is described and illustrated with comparative notes and host plant information.

New distribution records for Cerambycidae are presented for the Bahamas and for Andros Island specifically. Recent collecting has added 22 species to the fauna of Andros Island, increasing the total from 35 species to 57, and increasing the number of species in the Bahamas as a whole from 63 to 75.

Due to its astonishingly rich and imperiled biodiversity, the small island of Madagascar is globally significant in terms of species conservation. To contribute to the ongoing research and conservation efforts there, a taxonomic review of the Malagasy species of Sphindidae (Coleoptera: Cucujoidea) is provided. Five species are treated, representing two genera, Sphindus Megerle in Dejean and Aspidiphorus Zeigler in Dejean. Diagnoses, descriptions, illustrations and a taxonomic key are provided. Four new species are described: Aspidiphorus bisulcatus Forrester & McHugh, new species; Aspidiphorus inordinatus Forrester & McHugh, new species, Aspidiphorus protuberans Forrester & McHugh, new species; and Aspidiphorus quadratidentis Forrester & McHugh, new species.

Lissoderes longinoi, new species, and L. masneri, new species are described from specimens collected in Costa Rica and Ecuador, respectively. Lissoderes championi Hespenheide is reported for the first time to be associated with Cecropia angustifolia Trécul, and L. cecropiae Hespenheide reported for the first time with C. obtusifolia Bertoloni. The distribution of members of the genus along an elevational transect in Costa Rica is described, and the ecology of their association with the plant genus Cecropia (Cecropiaceae) is reviewed.

Several nomenclatural and bibliographic issues relating to Cerambycidae are discussed. Authorship of Parandra is attributed to Olivier (1803: 100) and the type species of the genus is Attelabus glaber DeGeer 1774 by monotypy. This implies several nomenclatural changes in the current classification of the New World Parandrini. Parandra laevis Latreille 1804 is an unnecessary replacement name for Parandra glaber (DeGeer 1774) and so a junior objective synonym of that species. Using the reversal of precedence application, Isocerus Illiger 1801 is considered a nomen oblitum and Neandra Lameere, 1912 a nomen protectum; similarly Trestonia Rafinesque 1815 is regarded as a nomen oblitum and Trestonia Buquet, 1859 a nomen protectum. Acanthocinus Schönherr 1817 is regarded as a nomen nudum. The type species of the following genera are discussed: Acanthoderes Audinet-Serville 1835 (Cerambyx daviesii Swederus, 1787); Anaglyptus Mulsant 1839 (Leptura mystica Linnaeus, 1758); Graphisurus Kirby 1837 (Cerambyx fasciatus DeGeer, 1775); Saperda Fabricius, 1775 (Cerambyx carcharias Linnaeus, 1758); Sternidius LeConte 1873 (Lamia alpha Say, 1827); Tmesisternus Latreille 1829 (Tmesisternus bizonulatus Guérin-Méneville 1831); and Tragocerus Latreille 1829 (Prionus bidentatus Donovan, 1805). In order to maintain nomenclatural stability, an application to the Commission should be submitted to reject the first valid type species designations of the following genera: Callichroma Latreille 1816 (Cerambyx moschatus Linnaeus, 1758); Cerasphorus Audinet-Serville 1834 (Stenocorus garganicus Fabricius, 1775); Dorcadion Dalman, 1817 (Cer
