NOTES ON DISTRIBUTION OF SPECIES. 



CICINDELID.E. 



Omus. All our species of this genus occur in Cali- 

 fornia, the headwaters of Kings and Tule Rivers in the 

 Sierras (Icevis), Fort Tejon ( calif ornicus), and Port Har- 

 ford along the coast (lecontei) being the southernmost 

 recorded limits. Two species dejeani and audouni - 

 extend their range northward into Oregon and Wash- 

 ington. The species occur in hilly and mountainous 

 regions only, so far as known. 



Tetracha. T. Carolina occurs at Yuma, especially 

 along the margins of pools, where they conceal them- 

 selves in the cracks or fissures of the drying mud banks. 



Cicindela. The species, with the exception of^ 12- 

 guttata and its varieties, are more or less local and only 

 found near water, none occurring along paths or dry, 

 sandy roads, as is true of several eastern species. C. late- 

 signata and C. sigmoidea are confined to the ocean beaches, 

 both being very abundant at San Diego in midsummer: 

 hirticollis occurs on various beaches and also at Yuma:
