Brathinus. B. californicus was found in some num- 

 bers by Mr. Hubbard at Lake Tahoe, where it occurred 

 in wet moss along a mountain stream; other specimens 

 were found at Sisson. 



Amphichroum. A. floribundum, very abundant in 

 many localities, especially on flowers of Ceanothus, in 

 April: puberulum, described from San Diego; specimens 

 taken in the San Bernardino Mountains are so referred 

 with some doubt. The species are more numerous in 

 the middle Sierras, and from there north to Vancouver. 

 The following are recorded from the State : sparsum, 

 scutatum, opaculum, flavescens, pallidum and maculatum 

 from the middle Sierras (Mariposa and Tahoe); bino- 

 tatum, pilosellum, alutaceum, modestum, from the region 

 about and to the north of San Francisco; testaceum and 

 crassicorne from still further north. 



Tanyrhinus. T. singularis occurs in the Santa Cruz 

 Mountains, but is quite rare. 



Lathrimaeum. One example of L. subcostatum obtained 

 in the mountain canon near Pomona, March. The fol- 

 lowing are recorded: pictum, northern; nigropiceum, 

 Santa Cruz County; spretum, Siskiyou; atrocephalum, 

 Tahoe (Fauvel). 



Homalium. This genus is numerously represented in 

 California, about half our listed species being recorded 

 from the State. H. plagiatum has occurred in mushrooms, 

 at Pomona, in early spring, and theveneti at Santa Barbara 

 and Redondo, on the ocean beach, in March; but, aside 

 from these, I am able to find definite records of only 

 four species from Southern California, viz.: strigipenne, 

 San Diego; repandum, ' 'Southern California and Texas" 

 (Fauvel); humile, San Bernardino Mountains, identified 

 by Casey; alutaceum, San Diego (Fauvel). When the
