except between and beyond the median carinae; hind femur about 4.0 times as long as deep; abdomen rather stout; tergite 1 about as wide as long, with sides sparsely, and median area beyond the basal de- clivity rather densely, punctate; tergites 2-6, except on apices, with numerous distinct punctures; tergite 7 rather smooth except for a few indistinct punctures; subgenital plate with a rather small, median basal, membranous excision; sheath about 0.7 times as long as ab- domen. Black, occasionally with abdominal tergites more or less piceous. Flagellum brownish beneath; clypeus piceous; palpi strongly fuscous; tegula pale yellowish; hind corner of pronotum narrowly pale yellowish brown; stigma blackish, with an obscure pale spot at base; legs rather uniformly reddish, with front coxa usually brownish or blackish basally, and hind tibia sometimes with obscure subbasal and apical infuscations. This species is unusually variable in body proportions, specimens ranging from moderately slender to rather stout. There is some indication from reared material that the body shape may vary accord- ing to the host and its environment, slender specimens being associ- ated with rather slender hosts living in slender stems, and stouter specimens with more stocky hosts living in fleshy structures such as seed pods. Careful breeding studies are greatly to be desired to obtain a better understanding of the nature of such variation. Specimens (439 cf, 4299): From Alaska (Big Delta, Cold Bay, Haines, King Salmon on Naknek River, Makushin Bay on Unalaska Island, and Naknek); Alberta (Banff and Lethbridge); Arizona (near Alpine, Oak Creek Canyon, and White Mountain Reserve east of McNary); British Columbia (Agassiz, Downie Creek in Selkirk Mountains, Hatzic Lake, Kelowna, Likely, Manning Park, Oliver, Revelstoke in Selkirk Mountains, Robson, and Williams Lake); California (Alameda, Albany, Antioch, Barton Flat, Benecia, Berkeley,
