COLEOPTERA OF SOUTHERN CALIFORNIA. 79 



whole State is considered, we must add the following: 

 algarum and rugipenne, from San Francisco; ater, from 

 Santa Cruz; pacificum, from Siskiyou; longulum, pusil- 

 lum, megarthroides, rivulare, lapponicum, ccesnm and 

 fractum, from "California," without indication of local- 

 ity. It is probable that few, if any, of these latter will 

 be found within our region. Several species in my 

 collection from Southern California are as yet un- 

 identified. 



Anthobium. A. atriventre and A. nigerrimum occur 

 on flowers, the former very abundantly at Pomona, in 

 April. Two other unidentified possibly undescribed 

 species are known to me from Pomona, Ojai Valley and 

 Palm Springs. The species of this genus are somewhat 

 numerous, but not identifiable as the literature now 

 stands. The following are to be added to the above: 

 aurifluum, diversicolle and subangulatum, from Lake 

 Tahoe; gilvipenne and punctatum, Santa Cruz County; 

 fraternum, northern; calif or nicum, "California." 



Orobanus. 0. rufipes, San Diego' and Pomona; one 

 example from the bank of a mountain stream near 

 Pasadena. 



Protinus. Two species of this genus have been found 

 on decaying mushrooms at Pomona, in early spring; 

 neither species has as yet been identified. In the 

 mountains of the middle coast region occur limbatus, 

 basalis and salebrosus: mdklini is middle or northern: 

 sulcatus is described from the middle Sierras. 



Megarthrus. M. pictus, reported from middle and 

 northern portion of the State. 



Lispinus. L. calif ornicus, not rare in many locali- 

 ties, under bark: linearis, less frequent, Riverside,
