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.E. 



Calopteron. C. reticulatum is recorded from " Califor- 

 nia" by Le Conte. 



Eros. E. Icetus is rarely taken in the San Bernardino 

 Mountains. 



Calochromus. C. dimidiata 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: corrusca 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.
