 have seen labeled " San Diego County:" molestus,

 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.

 Diego and Santa Barbara: volitans, several specimens 

 taken flying in the early evening; Pomona, August; 

 others at electric light, Pasadena (Fenyes).
