COLEOPTERA OF SOUTHERN CALIFORNIA. 173 



Ulosonia. — U. rnarginata occurs along the Colorado 

 River, under cottonwood bark. 



Merotemnus. — 71/. elongatus labeled " Cal." 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. — G. angustus is reported from the Colorado 

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

 caying base and roots of Yucca ivhipplei in various local- 

 ities; I have found it near Pomona in May. 



Metaclisa. — M. marginalis 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 

 limhalis 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:
