COLEOPTERA OF SOUTHERN CALIFORNIA. 175 



Helops. H. edwardsii is not rare, under bark, in 

 the San Bernardino Mountains: ovipennis, Mojave Des- 

 ert: rugicollis, Owens Valley and Tejon: strigicollis, " So. 

 Gal.," probably near San Diego (Horn): attenuatus, Val- 

 lecito (Colorado Desert) and Owens Valley. H. bachei and 

 H. blaisdelli are said by Blaisdell to occur under mari- 

 time plants growing on the sand-dunes near San Diego, 

 and one of these or a closely allied species I have found 

 very common in similar situations at Redondo Beach; 

 bachei was described from the Santa Barbara Islands, 

 and typical examples are perhaps found only on the 

 islands: discipula is described from the vicinity of San 

 Diego. 



The following species are more northern: opacus> 

 San Francisco and north, also Sacramento; punctatus, 

 "Gal.;" rugulosus, San Francisco; angustus, Tejon ; 

 californicus, San Jose, Lake Tahoe (beaten from pines 

 in July); tumescens, "Gal., Coll. of Ulke." 



^GIALITID^E. 



^)gialites. The exact locality of californicus is not 

 stated; it is doubtless northern, if really from the State: 

 fuchsii has been obtained in some numbers from Mendo- 

 cino County and Farallon Islands, by Mr. Fuchs. 



CISTELID.E. 



Xystropus. Horn expresses a belief, which I think 

 well founded, that X. californicus is an accidental im- 

 portation from Mexico or further south. The original 

 specimen was found at Martinez, on the shore of San 

 Francisco Bay, and has never since been duplicated. 



Stenochidus. I have taken specimens that are refer- 

 able to gracilis and cyanescens, at Pomona and Pasa- 

 dena, during May and June, but have not yet succeeded
