Aphodius browni Hinton. Linn Co., Santiam Pass, Hoodoo Ski Bowl   , 11­XII­77, G. L. Peters (OSAC).

Aphodius crenicollis Fall. Baker Co., Baker   , 11­V­61, BLT, KJG; Malheur Co., 14 mi SW Vale, 14­IV­71, rodent burrows, and Moore’s Hollow, 28­IV­76, squirrel burrow, KJG.

Aphodius fucosus Schmidt. Malheur Co.   , 15 mi SW Vale, 12­V­73 BLT, KJG.

Aphodius gentilis Horn. Hood River Co., Hood River   , 10­XII­78, at light, KJG, (ODAC); Jackson Co., Medford (RDGC).

Aphodius martini Van Dyke. Deschutes Co.   , 3 mi W Bend, in decaying vegetation, 4­ VII­62, D. R. Smith (OSAC).

** Ataenius nocturnus (Nomura)   . Jackson Co., Medford, 16­V­70, BLT. It is questionable if this species is adventive to the U.S. (Andrew Smith, in litt.); however, we believe it to be introduced in Oregon   .

** Ataenius spretulus (Haldeman)   . Jackson Co., Medford, 24­VII­2002, at lights, K. Love (ODAC, OSAC). This potentially serious turf grass pest had been recorded from all but five of the contiguous 48 states, including California ( Tashiro 1987, Stebnicka & Lago 2005). We believe it is a relatively recent introduction into Oregon since the Medford area was continuously trapped by black light for almost a decade, from the mid­1960s through the mid­1970s. If this species had been present in any numbers, we feel certain it would have been detected. Furthermore, reports of damage attributable to this species are currently confined to the immediate vicinity of Medford.

** Onthophagus nuchicornis (Linnaeus)   . This introduced dung scarab has been known in the Pacific Northwest, where it is widespread, at least since 1945, therefore we find it odd that it has not been recorded from Oregon. Marion Co., Salem, Minto­Brown Island Park , 11­VI­90, RLW, in dog scat, and Salem, 10­VII­2000, J. Walker; Morrow Co. , Swaggert Buttes, Sec. 15, T1 S, R26 E, 23­VI­79, RLW, in collector's dung; Polk Co. , 2 mi N Dallas, 18­IV­94, D. Driesner; Umatilla Co. , Hermiston, 26­VII­75 & 10­V­76, KJG. The following were taken from Japanese beetle traps placed by the Oregon Department of Agriculture : Clackamas Co. , Lake Oswego , Willamette R., Sec. 2, T2 S, R1 E, VII­88; 3 mi E Gladstone, 25­VIII­98; ca. 2 mi S Outlook, Sec. 35, T2 S, R2 E, 28­VII­99; Multnomah Co. , Portland, Sec. 25, T1 S, R1 E, 1­VII­99 & Sec. 17, T1 N, R2 E, 19­VII­99; Washington Co., vic. Tigard, Tualatin R., Pick's Landing, 16­ VI, 11­VIII­89; Hillsboro, Sec. 8, T1 S, R2 W, 12­VII­99   .

** Oxyomus silvestris (Scopoli)   . This introduced scarab has been known in the Pacific Northwest since 1930 and was first recorded from North America in 1871 ( Hatch 1971). Arnett (2000) listed it from “OR” without specific locality, but Skelley & Gordon (2002) recorded it only from New York, Pennsylvania, and Washington. We have seen one specimen from Multnomah Co. Portland, Forest Park, 2­IV­2003, ODAPMS with ethanol lure, T. A. Stafford.

** Rhyssemus germanus (Linnaeus)   . Yet another introduced species, this European native was reported by Gordon and Cartwright (1980) only from the Great Lakes and St. Lawrence River regions. The genus was previously unknown in the Pacific Northwest. One specimen, Deschutes Co., Bend, 2791 NE Broken Bow Dr., funnel trap with 2­ methyl­3­buten­1­ol lure, 6­VII­2004, A. Eglitis, USDA APHIS / FS Early Detection and Rapid Response Pilot Project   .
