Meristhus. — M. erlstatus occurs at Yuma, under debris 

 along the river bank; one example was also taken at 

 Riverside; found flying in the evening, in April, at 

 Pasadena (Fenyes). 



Chalcolepedius. — Le Conte records C. rubvipennis from 

 CajonPass; there is possibly some mistake in the locality; 

 tvebhii is common on willows along the Colorado River: 

 tartarus, rare in the same locality. 



Alaus. — A. melanops, southern and middle Sierras. 



Cardiophorus. — G. amplicollis, not rare on willows, 

 Pomona, Ojai, etc.; March and April: gemmifer, one

 throughout Southern California, December to June: 

 edwardsii, rare, Los Angeles County (Van Dyke): lat-

 Monica, Ventura, etc.; January to May. It is probable

 mon in the mountains farther north. C ceneus is appar- 

 ently not very common; I have seen specimens from 

 San Diego: seniciUits, rare; Pomona and Pasadena, 

 February and March. In addition to the above, bifas- 

 ciatus arid obscums occur about San Francisco; fenestra- 

 tus, coxalis and stigmaticus are northern; tutnidicoUis, 

 middle Sierras; dispar, eastern part of the State (Owens 

 Valley ?) ; abbrevlatus, crinitus and carbonatus are said 

 to be from " California." 



Horistonatus. — H. inanus and H. sujfiahts are not rare 

 at Pomona, Pasadena, etc., during May and June; taken
