          Abstract

          In North America, the tribe Cholevini (Coleoptera: Leiodidae) is composed of the genera Prionochaeta Horn with 1 species, Catoptrichus Murray with 1 species, Sciodrepoides Hatch with 3 species, and Catops Paykull with 17 species. The species are mostly forest inhabitants that feed on carrion and other decaying materials, but some occur in tundra habitats, in caves, and in rodent burrows. Resurrected status is proposed for Sciodrepoides terminans (LeConte). The subspecies status of Sciodrepoides watsoni hornianus (Blanchard) is not supported. Lectotypes are designated for Catops terminans LeConte (= Sciodrepoides terminans (LeConte)), Choleva gratiosa Blanchard (= Catops gratiosus (Blanchard)), and Choleva egena Horn (= Catops egenus (Horn)). Neotypes are designated for Catops simplex Say and Catops basilaris Say. Catops luteipes Thomson is reported from North America for the first time. New species are Sciodrepoides latinotum Peck and Cook sp.nov., Catops paramericanus Peck and Cook sp.nov., Catops apterus Peck and Cook sp.nov., and Catops meridionalis Peck and Cook sp.nov. Four Catops species are Holarctic in distribution, whereas the others are restricted to North America, south to Mexico.

          Résumé

          En Amérique du Nord, la tribu des Cholevini est constituée des genres Prionochaeta Horn, qui compte 1 espèce, Catoptrichus Murray, qui a aussi 1 espèce, Sciodrepoides Hatch, qui contient 3 espèces, et Catops Paykull, avec 17 espèces. La plupart des espèces sont des habitants des forêts qui se nourrissent de charogne ou d'autres matières en décomposition, mais certaines vivent dans des habitats de la toundra, dans des grottes ou dans des terriers de rongeurs. Nous proposons ici de rétablir Sciodrepoides terminans (LeConte). Le statut de sous-espèce de Sciodrepoides watsoni hornianus Blanchard n'est pas reconnu. Des lectotypes ont été choisis pour Catops terminans LeConte (= Sciodrepoides terminans (LeConte)), Choleva gratiosa Blanchard (= Catops gratiosus (Blanchard)), Choleva egena Horn (= Catops egenus (Horn)). Des néotypes ont été désignés pour Catops simplex Say et Catops basilaris Say. Catops luteipes Thomson est cité pour la première fois en Amérique du Nord. Sciodrepoides latinotum Peck et Cook sp.nov., Catops paramericanus Peck et Cook sp.nov., Catops apterus Peck et Cook sp.nov. et Catops meridionalis Peck et Cook sp.nov. sont de nouvelles espèces. Quatre espèces de Catops ont une répartition holarctique, les autres sont restreintes à l'Amérique du Nord, jusqu'au Mexique.

            The Entomological Collection of Thomas Say

            The 770 remaining specimens of the entomological collection of Thomas Say presently housed in the Museum of Comparative Zoology are catalogued for the first time, including 71 specimens representing 56 species described by Say which are labelled in Say's handwriting and which are probably those specimens on which Say's species descriptions were based. The history of the Say entomological collection is recounted. Based on signatures on labels in the present Say collection material, it is apparent that Say exchanged specimens with many European entomologists, including Dupont, Germar, Laporte de Castelnau, Motschulsky, Schoenherr, Sturm, and Wiedemann. A protocol for the designation of Say lectotypes and neotypes is proposed.
