COLEOPTERA OF SOUTHERN CALIFORNIA. 121 



on flowers at Pasadena in June and July, at Santa 

 Monica (Van Dyke), and at Tehachapi (Wickham): 

 gibbicollis is known by a single example taken near San 

 Bernardino in June by Dr. Fenyes, and by a single 

 specimen without definite locality in the Horn Col- 

 lection: illectus is found at Pomona and Pasadena by 

 sweeping late in June: lacustris, I am told by Dr. Van 

 Dyke, has occurred on white oak at Newhall (Los 

 Angeles County). 



Taphrocerus. — T. gracilis is introduced on the author- 

 ity of Van Dyke; Los Angeles County. 



LAMPYRID^. 

 Calopteron. — C. reticulatum is recorded from "Califor- 

 nia" by Le Conte. 



Eros. — E. hxtus is rarely taken in the San Bernardino 

 Mountains. 



Calochromus. — G. diniidiata occurs in the Mariposa 

 region and in Siskiyou County. 



Matheteus. — M. thevenetii is from the Mariposa region. 



Ellychnia. — E. californica is a common and widely 

 dispersed species: corrasca is less common than the 

 last, specimens in my collection having been found at 

 Riverside in May. 



Pyropyga. — P. fenestralis is not rare; specimens are 

 known to me from Riverside, Pomona, Needles and 

 Yuma: indicia is described from Lake Tahoe. 



Lamprorhiza. — L. riversi occurs in Sonoma County. 



Microphotus. — M. angustus is from central California. 



Pterotus. — P. obscuripennis is exceedingly scarce in 

 our district, and I have seen but one example from near 

 Pomona; it is more common further north.
