Abstract. Diadasia diminuta (Cresson, 1878) (Apidae: Eucerinae: Emphorini) uses Sphaeralcea St. Hil. (Malvaceae) as its pollen host throughout much of its range in dry habitats of the western U.S. and Central America. Here we document a regional shift in pollen host and habitat. Based on observations of foraging behavior spanning 1–11 years at 17 study sites and analyses of scopal pollen loads collected at nest entrances, we show that D. diminuta relies almost exclusively on a rare, fire-following mallow, Iliamna latibracteata Wiggins (Malvaceae), as its pollen host in relatively mesic forest habitats of northwestern California and southwestern Oregon. The generalized flowers of I. latibracteata attract a wide array of visitors, but D. diminuta is likely the most important pollinator; it was present at 16 of 17 sites and accounted for at least 70% of visits in more than half of 52 site-year visitor surveys. Although D. diminuta is widespread and abundant across most of its range, we argue that the rare disjunct populations studied here may be genetically distinct and perhaps represent a case of incipient speciation, making them worthy of conservation concern.

Abstract. The megachilid bees of the genus Chelostoma Latreille, 1809 in Montana, U.S.A., are reviewed. Two Palearctic species, Chelostoma (Foveosmia) campanularum (Kirby, 1802) and Chelostoma (Gyrodromella) rapunculi (Lepeletier, 1841), are reported for the first time from Montana. The Montana specimens represent a range expansion from southeastern Michigan for C. campanularum and from northeastern Illinois for C. rapunculi. These collections appear to represent an established local population for C. campanularum with specimens from multiple dates, years, and locations in Bozeman, Montana; specimens of C. rapunculi have only been found in one location and year. The habitat, distribution, and potential ecological impacts of establishment of these two non-native species in Montana are discussed. An identification key to the Chelostoma of Montana is provided.

Abstract. Scaphinotus longiceps Van Dyke, 1924 (Coleoptera: Carabidae) has formerly been recorded from only three sites (two of which are based on specimens collected in 1901 and the 1930s) in northwestern California. The limited known range, apparent restriction to old growth forests, and few specimens have caused this species to be regarded as potentially threatened or endangered. Ten additional sites have since been found, significantly increasing the known range and potential ecological amplitude of this poorly understood species. Habitus and other images are presented to aid in distinguishing this species from several related species found in the region.
摘要加州西北部的长尾甲虫(Scaphinotus longiceps Van Dyke, 1924)(鞘翅目:甲虫科)以前仅在三个地点(其中两个是基于1901年和20世纪30年代收集的标本)被记录下来。已知的范围有限，明显局限于古老的森林，以及很少的标本使该物种被认为是潜在的威胁或濒危物种。此后又发现了10个新的地点，大大增加了这种鲜为人知的物种的已知范围和潜在的生态幅度。生境和其他图像有助于将该物种与该地区发现的几个相关物种区分开来。
