(Coleoptera: Carabidae) is established in California.

Background: The ground beetle Bembidion (Neja) ambiguum Dejean is native to Europe and north Africa, in the Mediterranean region.

New Information: We report it from North America for the first time, from five localities around San Francisco Bay, California. The earliest record is from 2012.

Ground beetles (Coleoptera, Carabidae) of the Hanford Nuclear Site in south-central Washington State.

Carabidae) collected from the Hanford Nuclear Reservation and Hanford National Monument (together the Hanford Site), which is located in south-central Washington State. The Site is a relatively undisturbed relict of the shrub-steppe habitat present throughout much of the western Columbia Basin before the westward expansion of the United States. Species, localities, months of capture, and capture method are reported for field work conducted between 1994 and 2002.

Pterostichus (Anilloferonia) diana LaBonte (Coleoptera: Carabidae: Pterostichini), a replacement name for P. (A.) lanei (Hatch, 1935), and validity and redescription of P. (A.) malkini (Hatch, 1953).

A replacement name for Pterostichus (Anilloferonia) lanei (Hatch), 1935, is necessary because P. lanei (Hatch) is a secondary homonym of P. (Pseudoferonina) lanei Van Dyke, 1925.

Nebria brevicollis (Fabricius, 1792) in North America, benign or malign? (Coleoptera, Carabidae, Nebriini).

Nebria brevicollis (Fabricius) is one of the most frequently encountered and widely distributed carabid beetles in Europe. Until recently, the only North American records were based on two single specimens, both from the 1930's in southeastern Canada. In 2008, this species was found at thirteen different sites in five counties in northwestern Oregon.

Effects of tillage on the activity density and biological diversity of carabid beetles in spring and winter crops.

The effects of tillage regimen (conventional [CT] and no-tillage [NT]) on the activity density and diversity of carabid beetles (Coleoptera: Carabidae) was studied by pitfall trapping within a rain-fed cropping system in northwestern Idaho, 2000-2002. The cropping rotation consisted of a spring cereal (barley, Hordeum vulgare L., in 2000 and 2001; and wheat, Triticum aestivum L.
