130 CALIFORNIA ACADEMY OF SCIENCES. 



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. wQSiV paUipe'nnis, one exam- 

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



Chariessa. — G. elegans, one example taken at an alti- 

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

 County, by Mr. Daggett, is the only instance known to 

 me of the capture of this beautiful insect in Southern 

 California. G. 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. — G. rujipes occurs everywhere: rujicollis, 

 the only specimens seen from our district were taken 

 early in June on San Clemente Island. 



PTINID^. 



Trigonogenius. — T. fardiis 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
