COLEOPTERA OF SOUTHERN CALIFORNIA. 151 



Acanthocinus. A. obliquus and A. spectabilis are both 

 found in the higher parts of the southern Sierras, but 

 are more frequent in the middle and northern portions 

 of the range. 



Pogonocherus. Several examples of crinitus have been 

 taken at Pasadena by Dr. Fenyes, on live-oak, in June. 

 Professor Rivers reports the larva as occurring in dead 

 branches of Quercus agrifolia. P. mixtus occurs in 

 the middle or northern regions, and I have found ore- 

 gonus at Lake Tahoe. 



Lypsimena. L. californica is rare at Pasadena 

 (Fenyes); Santa Monica, August (Van Dyke); Yuba 

 County (Fuchs). 



Saperda. A form which passes as moesta is occa- 

 sionally found in Southern California, on cottonwood 

 trees; I have taken it at Riverside, in May. 



Oberea. 0. schaumii is rather uncommon; found on 

 willows in the foot-hills near Pomona in June; it has 

 been called quadricallosa, a name now regarded as a 

 synonym of the one given above. 



Tetraopes. One of the numerous color varieties of 

 femoratus is plentiful on milkweed throughout our 

 region in May and June. 



Idcemea. One example of californica was beaten 

 from live-oak, in June, and others were secured at 

 elecric light, at Pasadena, in April. 



Methia. Several examples of an unidentified species 

 were taken at electric light, at Pasadena, in September 

 (Fenyes); this is possibly mormona Linell. 



CHRYSOMELIDJE. 



Aulacoscelis. A. purpurea, Needles (Wickham). 

 Donacia. No specimens of this genus have yet been 

 found in our region, but the following six species are
