COLEOPTERA OP SOUTHERN CALIFORNIA. 187 



is abundant on Eriogonum cinereum, at Redondo, in 

 April and May; it has also been found in the foot-hills 

 near Pomona, but on what plant I am not now able to 

 say: velatus occurs in the " Sierra Nevada Mts. Mor- 

 rison:" naso is described from " Gal." 



Deporaus. D. glastinus is common on live-oaks, 

 especially when in blossom, throughout our region. 



OTIORHYNCHID^E. 



Minyomerus.. M. languidus, Fort Tejon (Horn). 

 Stamoderes. 8. uniformis, Sonoma County. 

 Agasphaerops. A. nigra, Mendocino County. 



Trigonoscuta. T. pilosa is abundant throughout the 

 year in the sand-dunes along the ocean front. 



Eupagoderes. E. argentatus, E. desertus and E. varius 

 inhabit the Colorado Desert, while geminatus and plum- 

 beus occur farther north, in Owens Valley. It is almost 

 certain that plumbeus is not distinct from varius. Spec- 

 imens of a species of this genus have been found at 

 Claremont, by Professor A. J. Cook; these are possibly 

 varius, but so far as seen they are uniformly vittate and 

 I am inclined to believe them different from anything 

 described. 



Rhigopsis. R. effracta is common on and about the 

 roots of various weeds, at Pomona, Pasadena, San Ber- 

 nardino, etc. Horn reports it as having been found 

 "feeding on yucca." 



Amotus. One example of gracilior was found on the 

 beach at Santa Barbara, in February; it is not rare at 

 Santa Monica (Albright): longisternus seems very close 

 to the preceding, and like it was described from Los 

 Angeles County.
