californica: ameus, nitidus, and vulneratus occur in the 

 central and northern parts of the State: obliqim* in 

 Santa Clara County. 



Callidium. C. antennatum, Mt. Wilson, Los Angeles 

 County (Van Dyke): hirtellum, San Bernardino Moun- 

 tains; not very common: vile, described from "Cal.;" 

 it is doubtless from the north. Le Conte mentions a 

 race of janthinum from California. 



Xylocrius. X. agassizii and X. cribratus are found in 

 the middle and northern Sierras. 



Malacopterus. M. lineatus, Colorado River, above 

 Yuma. 



(Erne. I have seen one example of gracilis from 

 Ontario (Los Angeles County) and one from Santa 

 Catalina Island; bred from the dead wood of Quercus 

 agrifolia at Poway (Blaisdell): costata is recorded from 

 ".Gal." 



Eucrossus. One example of villicornis was taken in 

 the San Bernardino Mountains. 



Haplidus. H. testaceus, " Cal." 



Brothylus. One example of yemmulatus was taken 

 011 Mt. Wilson (Van Dyke). 



Romaleum. The only specimen of simplicicolle seen 

 by me was taken on Santa Catalina Island; it is a 

 widely diffused species and should occur elsewhere: 

 seminitidum, one example in my collection, from the 

 Colorado River. 



Elaphidion. E. albofasciatum, taken in the foot-hills 

 along the southern border of the Mojave Desert (Coquil- 

 lett): imbelle, Poway (San Diego County); bred from 

 the dead wood of live-oak by Dr. Blaisdell, who says 

 that the beetles are common beneath bark in August.
