San Bernardino, but all others are from the immediate 

 vicinity of the coast. P. 'pacijica is described from Santa 

 Barbara. 



Microglossa. — Fauvel mentions the occurrence of 

 suturalis in "California." 



Aleochara. — A. mdcicollis 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 puherula 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 irova. 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. vespeins, Humboldt County. 



Bolitochara. — B. californica, common throughout the 

 State in or about fungi: nigrina is found near San 

 Francisco and in Humboldt County.
