COLEOPTERA OF SOUTHERN CALIFORNIA. 203 



Hylesinus. H. aspericollis is not rare in the southern 

 Sierras: specimens referred to imperialis have been seen 

 from the vicinity of San Francisco: sericeus is found in 

 the middle and northern Sierras. 



Phlceosinus. P. punctatus is common throughout the 

 Sierras: cristatus occurs farther north; it has proved 

 injurious to cypress hedges near Sacramento. 



Chaetophlceus C. hystrix, San Diego; rare. 

 Carphoborus. C. simplex, Mojave Desert. 



Dendroctonus. D. terebrans is common and D. fron- 

 talis rather scarce; on pines in the Sierras: similis and 

 simplex are said to occur in the State. 



Hylastes. H. macer and H. longus are common in the 

 coniferous forests throughout the State: gracilis is found 

 in the Tahoe region: nigrinus is common in the more 

 northern parts of the State; I have seen one example in 

 Mr. Fuchs' collection labeled San Diego County. 



Hylurgops. H. subcostulatus occurs throughout the 

 Sierras: granulatus and rugipennis are thus far known 

 only from the more northern parts of the State. 



ANTHRIBID^E. 



Toxotropis. T. approximatus was beaten from dead 

 twigs of live-oak, near Pomona, in June. 



Gonops. G. fissunguis, " Big Trees. " 



BrachytarsuB. I have seen four species from the 

 State, none of which are identified with certainty; one 

 of these is certainly exceedingly close to, if not identical 

 with, the eastern alternatus; specimens have been taken 

 at Redondo by sweeping. Two other species are from 

 Southern California.
