COLEOPTERA OF SOUTHERN CALIFORNIA. 109 



by sweeping: basalis, not common; Riverside, February 

 to May: simplex occurs at Yuma: Jiavidus, several ex- 

 amples taken at light, at Palm Springs (Fenyes): irans- 

 fugus, central and northern California: gracilis, about 

 Lake Tahoe. 



Esthesopus. — E. dispersus, " Southern California " 

 (Horn). Unquestionably a desert species. 



Cryptohypnus. — 0. squalidus, rare; found by washing 

 the gravelly margins of mountain streams near Pomona: 

 nodurnus, found in the north: fvmebris, recorded by 

 Horn from " California and western Nevada;" it is

Hypnoideus. — All the species occur along streams in 

 the mountains and foot-hills. H. striatulus has occurred 

 but once near Pomona, in May: gradarius is not com-

 persed: pectoralis, plentiful almost everywhere. 



Anchastus. — A. cinereipennis, a rather common spe-

 cities, from San Diego to the northern portions of the 

 State: hicolor var. desertus hoi?, been taken at Yuma: tan- 

 tillus and regitlaris are said to be from California, but I

 and one or both may be nothing more than a variety of 

 cinereipennis, which is somewhat variable. 



Elater. — E. hepaticus, a single example taken by sweep- 

 ing, near Pomona, June: fastus, "Southern California" 

 (Le Conte); I am unable to ascertain the exact locality 

 of a pair collected by Morrison, but very likely they are 

 from the southeast: cordifer, not common, under bark of
