estriatus, several examples taken near San Diego in the

 Diego (Casey): gaudens, San Diego, Ventura; uncom- 

 mon on sea beaches: serrulatus, rare; sea beaches, Sari 

 Diego, San Pedro: sulcifrons, common on beaches. 

 The following species are also Californian: rotundatus,

 cequipunctatus , ciliatus and vestilus, from near San Fran- 

 cisco; lentus, Truckee; opacellus, northern. 



Plegaderus. P. fraternus and P. nitidus are usually 

 common under pine bark in the Sierras: consors I 

 have seen labeled "San Diego County:" molestus, 

 described from Lake Tahoe. 



Teretrius. T. placitus, one example found flying early 

 in March at Pasadena (Fenyes): ohliquulus has been 

 taken at Santa Monica by Mr. Albright. 



Abraeus. A. bolteri, San Bernardino (Le Conte). 



Bacanius. B. globulinus, one example taken at Pasa- 

 dena is thus referred; it is not typical, but as northern 

 specimens show considerable variation, notably in the 

 development of the elytral striae, it is likely that the 

 differences shown are not specific. 



Acritus. A. maritimus, rare, on sea beaches; San 

 Diego and Santa Barbara: volitans, several specimens 

 taken flying in the early evening; Pomona, August; 

 others at electric light, Pasadena (Fenyes).
