COLEOPTERA OF SOUTHERN CALIFORNIA. 173 



Ulosonia. U. marginata occurs along the Colorado 

 River, under cottonwood bark. 



Merotemnus. M. elongatus labeled " Gal." is prob- 

 ably from the southeast. 



Aphanotus. A. brevicornis is rather common in the 

 eastern portion of San Diego County (Blaisdell); very 

 rare at Pomona, a single dead specimen being all that I 

 secured in seven years' collecting. 



Alphitobius. A. ovatus and A. piceus have both found 

 their way into our territory, though neither is as yet 

 common. Of the former species, I secured a specimen 

 under bark at Indio, in the Colorado Desert, and several 

 examples of the latter have been taken at Pasadena by 

 Dr. Fenyes. 



Cynaeus. C. angustus is reported from the Colorado 

 Desert: depressus is rather common in and upon the de- 

 caying base and roots of Yucca whipplei in various local- 

 ities; I have found it near Pomona in May. 



Metaclisa. M. marginalia is rather rare, occurring 

 under bark of pines in the San Bernardino Mountains; 

 also found at Julian (San Diego County). 



Uloma. U. longula is not rare under bark, in the 

 Sierras. 



Phaleria. P. rotundata is very abundant everywhere 

 on our seacoast from San Diego to San Francisco, oc- 

 curring beneath kelp. I have no hesitation in uniting 

 limbalis with the preceding; a long series shows every 

 grade in coloration from uniform testaceous to typical 

 limbalis, which is in great part black; a precisely analo- 

 gous variation is observable in the common testacea of 

 the Atlantic coast. P. debilis is reported from Yuma:
