COLEOPTERA OF SOUTHERN CALIFORNIA. 95 



I 



Epierus. E. regularis, San Diego, San Bernardino: 

 planulus, San Diego, Yuma (Horn): nasutus, Yuma, 

 under cottonwood bark (Horn). All these are doubtless 

 more common in the southeastern part of the State, 

 and are probably all to be found under the bark of 

 various trees, but especially cottonwood. 



Hetaerius. No species of this genus is yet recorded 

 from Southern California, but californicus has been 

 found at Sonoma, tristriatus at Calaveras, and morsus 

 at Fort Tejon. 



Onthophilus. 0. lecontei, very rare; three examples 

 taken at Pasadena, in December, under rotten squash. 



Paromalus. P. difficilis, Mojave (Horn); San Diego 

 (Fuchs): mancus is described from Humboldt County 

 by Casey. 



Carcinops. C. opuntice, not common at Pomona; more 

 abundant in San Diego County and the southeast, in 

 decaying Opuntia: tejonicus, a single specimen taken 

 under pine bark in the San Bernardino Mountains: 

 gilensis, one example, under chips on a freshly cut oak 

 stump, Pomona; common in Arizona in decomposing 

 cacti (Cereus): consors, said by Blaisdell to be common 

 in decaying vegetable matter in San Diego County. A 

 species found in numbers in decaying Yucca whipplei, 

 near San Bernardino, was identified by Horn as consors, 

 but a comparison with the type of this species makes 

 this reference doubtful: tenelhis, Colorado River, under 

 bark. Casey mentions seeing a specimen of 14-striatus 

 from Lake County, and I have recently seen the same 

 species from Lower California; it will probably be found 

 in our region. 



Anapleus. A. marginatus, San Diego County. The 

 species was described by Casey under the name compactus, 

 but is considered identical with 'marginatus by authorities.
