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. Cal." (Casey); probably from the 

 Colorado Desert: dilatatus, common everywhere: histri- 

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

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

 est species: cequalis, San Bernardino: funehris, South- 

 ern California (Casey): brevicollis, Riverside, Santa 

 Monica, Pomona; not very abundant: puhescens, San 

 Bernardino, Pomona, San Diego: sulcaius, 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: fulghiosus, discolor, gregcdis, pidverw- 

 ■lentus, parallelus, and inquisitus. 



Conibius. — C 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 Sylvania; it 

 was described from the Colorado Desert. The distinct- 

 ness of this and the preceding species I believe may 

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

 rather common under stones, in Owens Valley: crassipes 

 is described by Casey from '' So. Cal." 



Notibius. — N. puberulus, Colorado Desert, Needles 

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

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

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