most often taken: explanatus and erythrogaster are rather 

 scarce: desertus is found east of the mountains: prostans 

 is rather common in wet moss, at considerable elevations, 

 but is only rarely taken in the lower valleys: debilis and 

 seriatus are northern; of the latter I secured several 

 examples near San Francisco (Marin County). 



Thinopinus. T. pictus is not rare on various beaches 

 from San Diego northward; specimens in my collection 

 were taken at Redoiido, February; Coronado, June; 

 Santa Monica, August. 



Creophilus. G. villosus, wide-spread, but usually not 

 abundant; very common on San Clemente Island in 

 May and June, about the carcasses of birds and foxes 

 shot by hunters. 



Hadrotes. H. crassus is taken on sea beaches; 

 Redondo, March to May; Santa Barbara, February; San 

 Diego; not numerous. 



Staphylinus. 8. saphyrinus, not uncommon under 

 stones near water, especially in the foot-hills: luteipes, 

 less common; Pomona, January; Santa Barbara, Febru- 

 ary: tarsalis, quite rare, Pomona and Los Angeles: 

 rutilicauda, found in the middle Sierras: niyrellus, found 

 farther north: cinnamopterus is said by Horn to occur 

 from Maine to California; I have not yet seen specimens. 



Belonuchus. B. ephippiafus was taken abundantly by 

 Dr. Fenyes and myself under rotting squash, etc., Pasa- 

 dena, Pomona, etc., July to October. Specimens of an 

 apparently undescribed species were taken in decaying 

 yucca, in mountains near Pomona, May. 



Philonthus. I have found nitescens only along the 

 wet margin of a small salt lake or pond at Redondo, 

 April: alutaceus, taken sparingly in a low, marshy spot
