Hydnocera. H. robusta, Owens Valley (Horn): scabra, 

 rather common throughout the southern Sierras and the 

 adjacent region: discoidea, Palm Springs, April; Colo- 

 rado River (Le Conte): sp. near pallipennis, one exam- 

 ple, Pomona: bicolor, Colorado River (Le Conte). 



Chariessa. C. elegans, one example taken at an alti- 

 tude of over 6,000 feet in the Sierras, in Los Angeles

 California. C. dichroa, Los Angeles County (Coquillett), 

 is described from Sacramento. 



Cregya. G. fasciata is described from San Diego. A 

 specimen with entirely piceous elytra taken by me in 

 the San Bernardino Mountains is probably a mere color 

 variety. The species also occurs in northern California. 



Lebasiella. L. maculicollis occurs sparingly at Pasa- 

 dena and Pomona late in May and early in June. 



Corynetes. C. rufipes occurs everywhere: rufrcottis, 

 the only specimens seen from our district were taken 

 early in June on San Clernente Island.

Trigonogenius. T. farctus is not rare at San Fran- 

 cisco, where it has distinguished itself as an herbarium 

 pest. 



Sphaericus. S. gibbioides also occurs at San Francisco. 



Ptinus. The species of this genus are in some con- 

 fusion. Specimens of two species which have been 

 considered to be (and probably rightly so) interruptus 

 and verticalis are found quite commonly by beating live- 

 oaks and occasionally other trees or shrubs, October to
