COLEOPTERA OF SOUTHERN CALIFORNIA. 39 



CARABID.E. 



Omophron. 0. dentatum is quite common in many 

 localities along the sandy or gravelly margins of streams, 

 Feb. -Aug. This species, together with Bembidium, 

 Tachys and other littoral forms, is easily secured by 

 "washing" the banks. 0. ovale Horn and continuum, 

 solidum and gemma Csy. are northern. 



Trachypachys. T. inermis and T. gibbsii occur both in 

 the northern Sierras and in the Coast Range. I have 

 taken the latter at Lake Tahoe in July, and Mr. Dag- 

 gett has found it. at an elevation of 6,000 feet on the 

 Kern River. 



Cychrus. 0. obliquus, Los Angeles and San Diego; 

 not common: striatus, Santa Barbara, Pomona, Pasa- 

 dena; scarce along streams, where they conceal them- 

 selves under rocks and logs during the day: mimus, 

 somewhat more common than the last and occurs in 

 same situations; best obtained by trapping with fresh 

 meat: punctatus, San Diego County, common at Fort 

 Tejon (Le Conte): subtilis, Los Angeles, very rare; not 

 seen alive by the writer; the example in my collection 

 is from Tulare County; it is also reported from Mariposa. 



The following species also occur in the State: angusti- 

 collis, northern; cordctius, cristatus, interruptus, ventrico- 

 sus, striatopunctatus, region about San Francisco; ore- 

 ophilus, middle Sierras; fuchsianus, northern; dissolutus, 

 "Cal." In a recent review of the subgenus Brennus, 

 Casey has added the following names: basalis, duplica- 

 tus, incipiens, decipiens, symmetricus, gentilis, strictus, 

 convergens, sculptipennis , porcaius, sinuatus, politus, cor- 

 pulentus, compositus, longipes, gravidus, and catenulatus. 

 The last two are said to be from Southern California.
