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 (B\ichs). 



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 

 femoratiis 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. 



CHRYSOxMELID.E. 

 Aulacoscelis. — A. purpurea, Needles (Wickham). 

 Donacia. — No specimens of this genus have yet been 

 found in our region, but the following six species are
