the species near Los Angeles: vicina, common in decay- 

 ing fruit of CtLcurbita, also between the leaves and in the 

 decaying flower-stalk of Yucca v)hipplei: neglecta, rare, in 

 decaying squashes; San Diego (Blaisdell); unknown to 

 me: populnea, not common; one example, under bark, 

 Riverside, May; more common in the desert portions 

 of San Bernardino and San Diego counties. 



Hister. — H. seMatus, " not common, in spring and 

 early summer flying about sandy places near streams; 

 also found about the roots of plants" (Blaisdell); I 

 have found it rarely in spring at Pasadena, and in 

 small numbers under plants growing near the beach at 

 Santa Monica, August: lucanus, Southern California 

 (Horn): simplicipes, one example, San Diego County: 

 sexstriatuff , not common, occurring in early spring, fly- 

 ing or resting beneath boards or about the roots of 

 plants in grassy places; Riverside, Redondo, Pomona, 

 San Diego: militaris, Yuma (Horn); in some seasons 

 quite common, frequenting the sandy banks of streams; 

 San Diego (Blaisdell): bimaculatus, one example found 

 dead near a small stream, Riverside: lecontei, specimens 

 in the Horn Collection from the southeastern portion of 

 the State: pimctiger, common under pine bark in the 

 Sierras: reviotus, recorded from Tejon (Horn): fracti- 

 frons, Lake Tahoe: umbilicatus, Marin County: Immunis, 

 from "California," in Horn Collection. 



Tribalister. — T. ruarginellus , "rare, taken from beneath 

 rocks in moist places " (Blaisdell);! cannot help thinking 

 there is some mistake here, as niarginellus is a rare east- 

 ern species, the only examples known to me being the 

 type described from Maryland, and a single example 

 taken by myself in Rhode Island. 



Tribalus. — T. californicus is common under leaves and 

 stones in moist places near water courses.
