specimen from under a stone in San Antonio Canon, near 

 Pomona, Horn gives as localities Owens Valley, Tejon, 

 and the southern Coast Range. 



Eurymetopon. — E. rufipes is plentiful in the eastern 

 or desert portions of Southern California: fusculum, 

 Yuma, March (Daggett): convexicolle , very abundant 

 throughout the region to the west of the mountains, 

 occurring under bark, stones, and rubbish: sodalis, 

 Owens Valley, Yuma: serratum, Palm Springs, April: 

 infiatum, at times obtainable in some numbers beneath 

 the vegetation growing on the sand-dunes along the 

 shore from Santa Monica to San Diego: hicolor and cy- 

 lindricum have been taken in Kern County; of the 

 former I have specimens taken at or near Bakersfield in 

 May. 



Emmenastus. — E. longulus is rather common, though 

 less plentiful than Eurymetopon convexicolle with which 

 it occurs (see above): piceus, San Diego and San Ber- 

 nardino counties; Blaisdell records typical specimens 

 from Julian, at an altitude of 6,000 feet: obesus, San 

 Diego; "plentiful under dry cow manure, boards, rags, 

 etc." (Blaisdell): ihoracicus, San Gorgonio Pass (Casey): 

 obtusus and ater belong to middle California; I have 

 seen numerous specimens of the latter from San Fran- 

 cisco, and Casey mentions Napa and Sonoma counties 

 for the former: crassicornis is described from Humboldt 

 County. 



Epitragus. — E. pruinosus, Owens Valley (Horn); 

 Pomona, two examples obtained by beating late in July, 

 uncommon; San Diego, ''taken in net from Rhus 

 laurina and also beneath bark at the base of rotten 

 trees."
