COLEOPTERA OF SOUTHERN CALIFORNIA. 183 



our region: lustrellus is described from San Francisco: 

 humboldti, described from Humboldt County: nevadensis 

 has been found at Tallac, by Dr. Fenyes: serratus and 

 apicalis are both credited to California by Dr. Horn, 

 but there is reason to suspect that his specimens were 

 not properly referred. Three other species of doubtful 

 standing, but probably undescribed, are known to me 

 from Southern California. 



Mecynotarsus. — M. delicatidus, Yuma and Pasadena, 

 April; several examples taken at electric light. 



Xylophilus. — X. hrunnipennis is not common; I have 

 seen examples from San Bernardino, Pomona, and 

 Pasadena. This is the species described by Casey as 

 saginatus, but there appears to be no need for a new 

 name. X. hrunnescens, X . nucleus and X. constrictus are 

 known only from one or two specimens each, and all are 

 from the higher parts of the southern Sierras; constrictus 

 has also been found at Lake Tahoe. 



PYROCHROID.E. 



Pyrochroa. — P. californica was recently described by 

 Dr. Horn, from specimens taken in Los Angeles Couixty 

 by Coquillett; it is undoubtedly a rare insect. 



MELOID^. 



Cysteodemus. — G. armatiis occurs at many places on 

 the Colorado Desert; taken in numbers at Yuma, in 

 March, by Mr. Daggett. 



Meloe. — M.harharus, Santa Barbara Islands(Le Conte): 

 strigulosus, a specimen so referred was taken by me at 

 Palm Springs: opacus is northern. 



Nomaspis. — N. suhlce.vis, from Fort Tejon.
