 "Gal." 



Eucrossus. One example of villicornis was taken in 

 the San Bernardino Mountains. 



Haplidus. H. testaceus, li Cal." 



Brothylus. One example of yemmulatua was taken 

 on 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. albofaxc'mtu.iH,, 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.
