COLEOPTERA OF SOUTHERN CALIFORNIA. 75 



Pseudopsis. — P. obliteratu, P. detrifa and P. minuta 

 occur not uncommonly, and occasionally in large num- 

 bers, in the vegetable detritus along our mountain 

 streams; the first named species was described from the 

 valley of the Gila. 



Oxyporus. — Specimens of an undescribed species have 

 been taken at Lake Tahoe in Nevada by Mr. Schwarz, 

 and on the California side of the lake by Dr. Fenyes. 



Bledius. — The species are numerous, and are found 

 for the most part burrowing in wet sand or mud on the 

 margins of fresh-water streams and ponds. B. diago- 

 nalis is recorded by Le Conte as occurring on salt marsh 

 at San Diego: crihricollis appears to be confined to the 

 sea-coast; I have seen it in abundance on the beach at 

 Santa Barbara in February, but it is likely to be plenti- 

 ful at all seasons: ferratus, jacobinus, Jiavipennis and 

 eximius are all reported from San Diego, but I do not 

 know them in nature: opacifrons, San Diego and Los 

 Angeles: luteipennis, San Bernardino: arinatus, River- 

 side, Pomona, Long Beach; not common: nitidiceps, 

 Los Angeles, Wilmington (Le Conte), Pomona, one 

 example in nearly dry bed of brook, November: relictus, 

 two examples, Pomona: laticollis, common, many locali- 

 ties: rusticus, rare, Pomona: 7'ujicornis, abundant every- 

 where: clarus, Riverside, Pomona, not common; pleu- 

 ralis, occasionally common; once taken in numbers in 

 San Dimas Caiion near Pomona, April : ornatus, not 

 rare near the sea-coast, rare inland; taken in numbers 

 at Redondo, February: forcipatus, Yuma (Le Conte): 

 pundatissinius a,n.d phytosinus are recorded from "South- 

 ern California" without definite locality. A single speci- 

 men of a small black species not yet determined has 

 been taken at Pomona. The following occur further
