COLEOPTERA OF SOUTHERN CALIFORNIA. 101 



commoner further north: nigritus and ventralis have 

 both been taken at Los Gatos and in the middle Sierras: 

 ^ulcatulus a,nd fid us are Californian without more definite 

 locality. 



Cartodere. — G. argus, several examples on drying yucca 

 pith at Pomona: quadrifoveolata, a single specimen, Los 

 Gatos . 



Revelieria. — R. califomica was taken in company with 

 Metophthalmus rudis, in woody fungus, Ojai Valley, 

 March. I have seen specimens from "Los Angeles 

 County" and Los Gatos. 



Corticaria. — The various species occur under bark, 

 and are frequently taken on the wing at sunset or in 

 the early evening, and occasionally come in numbers 

 to electric lights. None of the species appear to be 

 very abundant, but several would doubtless prove com- 

 mon enough if properly looked for. I have seen 

 specimens of planida from Pomona, Pasadena, Ojai 

 Valley, and also from several locations in the central 

 and northern part of the State; the majority of speci- 

 mens have been taken flying, in early spring evenings. 

 C serrata, G. elongata and G. ferruginea are cosmopolitan 

 species; a moderate number of the last two have been 

 seen from Los Angeles County: serrata is apparently 

 rare in this region: occidua and tenuipes have thus far 

 occurred only in the Sierras, the latter being known 

 only by the type, which was taken in the San Bernar- 

 dino Mountains: inopia is known from the Tahoe region; 

 prionodera is from the middle coast region. 



Melanophthalma. — The species of this genus occur on 

 vegetation, and may usually be taken plentifully by 

 beating and sweeping. M. casta has been taken at 

 Pomona, Pasadena and Redondo, by sweeping weeds:
