north: deceptivus, sp. nov, Kern County; of Casey's

 cisco, lectus, foraminosus, gentilis, gracilis and bicolor 

 somewhat farther north, parvicollis in Mendocino 

 County, monticola at Lake Tahoe, and villosus from 

 California". 



Platystethus. P. americanus occurs chiefly about 

 cow-droppings, both east and west of the mountains. 



Oxytelus. 0. sculptus, not rare about stables, etc.: 

 sobrinus, one example, Pomona, December: laqueatus, 

 nitidulus, vegrandis, and niger are found near San Fran- 

 cisco and farther north, the last-named species and 

 montanus occurring at Lake Tahoe. 



Haploderus. H. flavipennis and H. cephalotes are both 

 often taken in the vegetable detritus which collects in 

 damp situations along streams or ponds: linearis is quite 

 surely more northern in habitat: annectens, reported 

 from San Francisco and Sonoma County. 



Trogophlceus. T. giice and T. pacificus are common 

 under rubbish about gardens and along water courses at 

 Pomona: diffuses occurs along streams in the higher 

 parts of the Sierras: prominens, one example, Los 

 Angeles (Casey): confinis, deMlis, and blediimus are 

 described from San Diego: paupercuLus &ndfilum, from 

 Yuma: armatus, occiduus, and lithocharinus are from the 

 middle coast region: lapsus and obliquus, from the mid- 

 dle Sierras (Truckee and Lake Tahoe): sculptilis, from 

 Sonoma and Lake counties: insolitus, from Hoopa Valley, 

 Humboldt County. Wickham reports giice, dentiger, and 

 tantillus from Yuma. There are several unidentified
