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

 species, strenuus and monstratus occur at San Fran- 

 cisco, lectus, foraminosus, gentilis, gracilis and bieolor 

 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 . cephaiotes 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. gil<% and T. pacificus are common 

 under rubbish about gardens and along water courses at 

 Pomona: diffusus occurs along streams in the higher 

 parts of the Sierras: prominens, one example, Los 

 Angeles (Casey): conjinis, debilis, and blediimus are 

 described from San Diego: pauperculus andfilum, 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 gilce, dentiger, and 

 tantillus from Yuma. There are several unidentified 

 species in my collection, some of which may be unde- 

 scribed.
