It has been taken up to 9,000 feet in the southern Sierra Nevada. The flight period of C. fraterna is restricted to the warmer months but appeqs to extend somewhat longer than in related species, with records from March to September in the San Francisco Bay area and at scattered stations inland, from March (Oro- ville) to October (Milton, Calveras County, and Palmdale). The species C. fratem and C, nigrescens are closely related. In C. fraterna the tibiae are in- fuscated, in C. nigrescens yellow. Both have all femora black and thereby differ from the allied species C. utrata that has mid and hind femora at least partly yellow.

Generally, this species is ecologically more restricted than most of the other of the state's widespread muscids, ranging only to the canyons at the margins of both the de- serts and the Great Basin on the east side of the Sierra Nevada, while in the mountains it occurs mostly at low to moderate elevations, with one re- cord at timberline in the southern Sierra Nevada. The species F. benjadni is recorded from 31 coun- ties and approximately 155 localities, based on an examination of 516 specimens, of which 13 were males, 503 as females. The male has a tight cluster of posteroventral bristles on a slight swelling situated one third length of femur from its apex. Both sexes may US- ually be separated from allied taxa by having the third antennal segment entirely black or nearly SO, and the arista browned at base. The species, pro- bably the female, is known to be annoying to man by attempting persistently to alight on the face (Mal- loch, 1913: 626), and in particular the region of - - .__ - ._ - - _- -- the eyes, ears, nostrils and lips.

Probably the adults are active throughout most of the year in various warmer parts of the state, as they have been collected from January to September in cismon- tane southern California, in January in the Owens Valley, and from February to October in the San Francisco Bay area and the Sacramento Valley, and as late as October in the San Joaquin. However, records are too scattered to give a complete pic- ture. In the mountains Hydrotaea &pes has been collected from April in the foothills through the summer at moderate elevations, ranging up to 8,500 feet in the central Sierra Nevada and above 10,000 feet in the White Mountains. The species A. &pes is recorded from 40 counties and 93 localities, based on an examination of 147 specimens, of which 39 were males and 108 females . Adults, along with those of Fmnia benjdni, have been found to associate with tabanids for the purpose of feeding on the blood of horses from pre- existing wounds (Garcia and Radovsky, 1962: 1115). 2.- 2.- - ,n Larvae of H. &pes are coprophagous and seeming- Map 50.

Oliviera (1941: 346-347), observing the habits of adults on the seashore at Mangaratiba, southern Brazil, concluded that the larvae bred on decaying animal debris washed up on the beach by the sea, and he has drawn attention to the fact that adults were frequently found in slaughterhouses devoted to the processing of animal products. Sabrosky (1949: 428) has recorded adults of 0. aenescens from Hawaii that were reared from larvae in rotten meat. John- son and Venard (1957: 21-26), comenting on the bio- logy of the species in Ohio, reported its presence in all stages throughout the year, and that experi- mentally none were capable of withstanding freezing temperatures. It was claimed that survival of adults during the winter months may possibly be associated with their habit of remaining on and secluding themelves in fermenting garbage. - _... - Ophyra 1 eucos toma (Wi edemann) Map 55.
