COLEOPTERA OF SOUTHERN CALIFORNIA. 171 



Trichoton. T. sordidum occurs at Palm Springs, in 

 April, under boards, stones, etc., as is generally true of 

 the Blapstini. 



Ulus. U. crassus is common in many localities: latus, 

 along the San Diego River (Blaisdell). 



Blapstinus. B. longulus, Yuma, San Diego (Blais- 

 dell): validus, "So. Gal." (Casey); probably from the 

 Colorado Desert: dilatatus, common everywhere: histri- 

 cus, Los Angeles County (Newhall): coronadensis , rather 

 common at Coronado (Blaisdell): rufipes, our common- 

 est species: cequcdis, San Bernardino: funebris, South- 

 ern California (Casey): brevicollis, Riverside, Santa 

 Monica, Pomona; not very abundant: pubescens, San 

 Bernardino, Pomona, San Diego: sulcatus, Riverside, 

 San Diego, Ojai Valley; rather common. The follow- 

 ing species are described from the middle and northern 

 parts of the State; their identification is a matter of 

 much difficulty: fulginosus, discolor, gregalis, pulveru- 

 lentus, parallelus, and inquisitus. 



Conibius. G. parallelus is said by Blaisdell to be 

 rather common about San Diego and Poway, but I have 

 not yet detected it in the vicinity of Los Angeles; it 

 was described from San Jose: seriatus is common in Los 

 Angeles County, and occurs as far north as Sylvariia; it 

 was described from the Colorado Desert. The distinct- 

 ness of this and the preceding species I believe may 

 fairly be questioned. C. elongatus is said by Horn to be 

 rather common under stones, in Owens Valley: crassipes 

 is described by Casey from " So. Gal." 



Notibius. N. puberulus, Colorado Desert, Needles 

 (Wickham), not rare at Palm Springs in April: puncti- 

 collis, rather frequent at Riverside, Pomona, and Pasa- 

 dena; often seen on city streets and walks: granulatus,
