near Pomona, November to January: semiruber, rare; 

 two examples only taken along a stream in foot-hills 

 near Pomona: hepaticus, very scarce, same locality as 

 preceding: flavolimbatus, has occurred at Pasadena in 

 November, but is very rare west of the mountains; not 

 rare at Yuma: grandicollis, not common; my specimens 

 were taken in the bed of the Los Angeles River, near the 

 city, in August: longicornis, widely distributed, but not 

 very common: discoideus, rare at Pomona about stables: 

 tdumnus, the form with red thorax and elytra is very 

 common at Yuma, on the river shore: pettiti and trian- 

 gulum, not rare, many localities: ferreipennis , rather 

 infrequent, Pomona, June to September: sordidus, com- 

 mon about houses and stables: versutus, two speci- 

 mens only, San Bernardino Mountains, elevation 5,000 

 feet: virilis, not rare, same locality as the last: nigritu- 

 lus, everywhere abundant: instabilis, has occurred on 

 one occasion at Mojave: quadridus, not infrequent in
