tall grass or rush both living (June) and dead (Novem- 

 ber): annexa, not rare; Pomona, June to November: 

 tristis, specimens so referred by Dr. Horn were bred in 

 numbers from cactus by Professor A. J. Cook, at Clare- 

 mont: postica was described from northern California, 

 and osculans and 4-oculaia from "California" simply. 



Hyperaspidius. — H. trimaculatus, widely dispersed but 

 not very common: (irciLatus, Colorado River (Le Conte). 



Scymnus. — A few specimens of Ucdatus were beaten 

 from pines in the San Bernardino Mountains: sordidus, 

 scarce; San Bernardino, Pomona: guttulatus, occurs at 

 Pomona, Pasadena, Redondo, Catalina Island, etc., 

 most frequently in March and April, but at no time 

 common: nehidosus, tolerably common in the foot-hills 

 near Pomona; taken also in the Ojai Valley and at Cata- 

 lina Island: pallens, common on live-oak nearly every- 

 where, especially from October to February: mimuf^, 

 two examples only; Riverside and Pomona: cindus, 

 moderately common and wide-spread: pacijicus, rare; 

 Sierras, 3,000 to 5,000 feet elevation: Jiebilis, two ex- 

 amples taken at Yuma: cervicalis, rare; Pomona and 

 Catalina Island: mceginicollis, our commonest species 

 and the only one occurring in orchards as well as on 

 wild growth: ardelio, nearly as abundant as the pre- 

 ceding and very widely dispersed, but does not occur 

 on cultivated lands: pundum, common, especially on 

 live-oak, in many localities: mtmis, less frequent than 

 the preceding but equally wide-spread: coniferarum, very 

 abundant on pines in the southern Sierras. The fol- 

 lowing species are more northern in habitat: debilis, 

 San Jose and Alameda; hisigmdus, Siskiyou; p/ieZp.s?7, 

 northern; caurinus, Owens Valley (Horn). 



//i7 Scymnillus. — S. aterrijSus is moderately common in the 



San Bernardino Mountains, probably on pines; taken 

 by beating.
