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: 

 inflatum, at times obtainable in some numbers beneath 

 the vegetation growing on the sand-dunes along the 

 shore from Santa Monica to San Diego: bicolor 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): thoracicus, 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."
