COLEOPTERA OF SOUTHERN CALIFORNIA. 85 



Chilocorus. — C. biviUnerus, plentiful about orchards 

 and cultivated grounds everywhere: cacti, generally 

 much less frequent, probably more common in the 

 southeast. 



Exochomus. — E. pilatii, generally quite rare; on one 

 occasion I found it in some numbers in an olive orchard 

 at Pomona, where it was feeding on the black scale with 

 which the trees were infested; it has also been found 

 rather plentifully at Pasadena, by Mr. Daggett, on cer- 

 tain pepper trees (Schinus molle) infested by this same 

 scale. E. californicus occurs in the Sierras from the San 

 Bernardino Mountains to Siskiyou, and also in Marin 

 County: fasciatus is common throughout our district: 

 childreni has occurred at Pasadena and Redondo: histrio, 

 Pomona, in the foot-hills. 



Cryptognatha. — C. pusilla, abundant near Pomona, on 

 live-oak, October: catalinoe, a small number taken by 

 beating on Catalina Island, August; probably not differ- 

 ent from the preceding. 



Smilia. — S. reversa, occurs on pines in the Sierras 

 (San Bernardino and Lake Tahoe), and is apparently 

 not uncommon: ovalis, specimens so referred are com- 

 mon on live-oak at Pomona, September to November. 



Hyperaspis. — The species occur by beating and sweep- 

 ing the shrubbery and herbage of uncultivated ground. 

 H . Jiinhinolata and its variety dissoluta are represented in 

 my collection by single specimens taken at Pomona in 

 May and June: lateralis is our commonest species: 

 undulata (?) is also rather common and very variable: 

 tceniata, not rare at Pomona and Pasadena: excelsa, rare, 

 Pomona, November; Pasadena, April; San Bernardino 

 Mountains, July: spiculinota, not common at Pasa- 

 dena and Pomona; usually if not always on a species of
