San Bernardino, but all others are from the immediate 

 vicinity of the coast. P. pacifica is described from Santa 

 Barbara. 



Microglossa. Fauvel mentions the occurrence of 

 suturalis in "California." 



Aleochara. A. sulcicollis occurs only on the beaches, 

 where it is quite abundant; several other species are 

 generally common in excrementitious matter. One 

 example of what seems surely identical with the Euro- 

 pean puberula has been taken at Pomona. 



Maseochara. M. valida, found at Pasadena, April to 

 July, under decaying fruits and vegetables: puberula, 

 one example at Arrowhead Hot Springs, May 31. 



Thiasophila. Several specimens of a species taken at 

 Pomona early in September: asperata occurs at Lake 

 Tahoe and Truckee. 



Isoglossa. A fine species, doubtfully referred to this 

 genus, occurred in the San Bernardino Mountains in 

 July: arcuata was described from Lake Tahoe. 



Oxypoda. About five species of this genus are known 

 to me from Southern California. Casey describes fusti- 

 ger from Humboldt County, and californica from "Cal." 



Myrmecochara. An undescribed species from Lake 

 Tahoe (Schwarz). 



Autalia. A. elegans, Lake County. 



Thinusa. T. maritima is described from Oakland. 

 I have found a closely allied if not identical species on 

 the beach at Santa Barbara. 



Silusa. S. vesperis, Humboldt County. 



Bolitochara. B. calif arnica, common throughout the 

 State in or about fungi: nigrina is found near San 

 Francisco and in Humboldt County.
