Wallowa Co., Imnaha, 6­V­76, KJG; Hells Can., Camp Creek to Lookout Creek, 9­11­V­91, RLW. ** Cassida rubiginosa (Müller) . This introduced European species feeds on various thistles and appears to have only recently moved into Oregon. Columbia Co. , Sauvie Island , 45.74019°, ­122.83509°, 31­V­2005 ; Multnomah Co. , ~ 2 mi NW Banks , Sell Rd. , 45.65114°, ­123.13671°, 27­IV­2005 and Sauvie Island , 45.71834°, ­122.83560°, 12­V­ 2005 , all on Canada thistle, R . A. Worth , M. Peters . ** Chaetocnema concinna (Marsham) . Marion Co., 3 mi E Mt. Angel, 1­X­2004 , feeding on leaves of strawberry, J. Bernard, J. Todd (ODAC, OSAC, WFBM, USNM). This is a new western U.S. record. This species was first reported in North America by Hoebeke (1980) , based on a specimen collected in Massachusetts in 1979. James Todd, a consulting entomologist, reported ( in litt .) that in western Oregon the adults occur during late summer and early fall. Leaf damage was observed first during fall, 2003, with more severe damage in 2004; there was no evidence of plant damage that might be attributable to larvae, none of which have been found; and strawberry plantings in the Willamette Valley have been sampled on a regular schedule for 25 years. Thus, it seems that this is a relatively recent introduction into the area. Chaetocnema concinna is a Palaearctic immigrant recorded from eastern Canada , the northeastern U.S. , and Texas ; and is recorded from plants in 10 families. Probably all do not serve as larval hosts, including strawberry ( Fragaria ) which is in Rosaceae . It seems to favor hosts in Chenopodiaceae and Polygonaceae and, in its native range, is injurious to crops (but apparently not strawberry) ( LeSage 1990 , White 1996 , Riley et al . 2003 , Clark et al . 2004 ). Chaetocnema labiosa White . Harney Co. , 40 mi E Burns, 8­VII­66, ex rabbitbrush, KJG. Crepidodera opulenta (LeConte) . Baker Co., Baker, 4­VI­59, on willow, KJG; Jackson Co., Ashland, 14­V­52, J. E. Davis; Lake Co., Buck Creek, 22­V­52, Black & Davis; Umatilla Co., 10 mi W Langdon Lake, 4­VI­64, on willow, KJG; Wallowa Co., 7 mi W Wal­ lowa, 17­V­49, J. E. Davis. Parry (1986) recorded this species from no farther north than northern California . Because of taxonomic confusion in this genus, it seems probable that some specimens treated under C. nana (Say) by Hatch (1971) represent C. opulenta . Cryptocephalus confluentus confluentus Say . Harney Co. , 5 mi N Alvord Ranch, 23­IX­ 71; Pike Creek, 8.5 mi NE Andrews, 4­IX­75; 10 mi SE Princeton, 28­VII­76; 10 mi S Fields, 16­VII­78, KJG; 3 mi S Fields, 15­VII­76; SE Sec.32, T39S, R35E, Arizona Creek, 7­VI­78, RLW (ODAC). Wheeler Co., Ochoco Summit, 30­VII­72, Musgrave (OSAC). Diabrotica virgifera virgifera LeConte . The first Oregon specimens of this pest, known as the western corn rootworm, were taken on a yellow sticky trap placed in field corn, Malheur Co., 2 mi S. Weiser Jct., mid­VIII to late IX­85, KJG. Although the specimens may be lost, records in the ODAC confirm this find with a determination made by RLW. This insect has been known to occur for many years in adjacent SW Idaho . According to Ben Simko (personal communication) it occasionally causes damage to corn in that area. Neochlamisus moestificus (Lacordaire) . This species, widely ranging in the U.S. and Mexico , was first recorded from Oregon by Karren (1972) without full data. The record was based on a specimen from Wheeler Co., Mitchell, 9­IX­68, RLW, on Eriogonum microthecum Nuttall. Others from that locality were collected 15­VIII­75, RLW & RLP; Malheur Co., 17.7 mi SW Owyhee, 29­VII­71, RLP & RLW, on E. microthecum and 15 mi SW Adrian, 31­V­73, KJG. ** Oulema melanopus (Linnaeus) . Commonly known as the cereal leaf beetle, an economic pest of considerable concern, Riley et al . (2003) recorded it from Oregon without specific data. This exotic was found for the first time in Oregon , Malheur Co., vic. Nyssa, Sec. 4, T19S, R47E, 21/27­IV­99; vic. Ontario , Sec. 22, T18S, R47E, 27­IV­99, swept from winter wheat, B. Simko (ODAC, OSAC); and Adrian, 16­VI­99, ex. oats, B. Bai. Later, survey and other collections by ODA staff provided the following county records: Baker Co., Wingville, NE, NE Sec. 27, T8S, R39E, 1­VI­99; Benton Co., Philomath, 18­ VII­2001 ; Crook Co., vic. Prineville, 7­VI­2002 , spring wheat; Deschutes Co., Terrebonne, 44°21.037, 121°19.597, 15­VII­2003 , sweeping wheat; Jefferson Co., near Culver, 10/ 18­VI­2003 , wheat; Lincoln Co., Lincoln City, Nelscott, SW Sec. 22, drift line on beach, 10­IV­2004 : Linn Co., near Scio, on oats, 26­VI­2002 ; Marion Co., S.
