not pigmented. Urogornphus (Fig. 8) two-segmented, first segment 
broadly triangular, second segment slender, nearly cylindrical, 
about as long as the first segment. Membrane of apex of pseudopod 
(Fig. 8) with four small dark hooks, each with a bifid base. 
Length 3.0 mm. 
Material examined. Two specimens 9 November 1977 and three 
specimens 6 December 1977, White Point, San Pedro, Los Angeles, 
California, associated with numerous adults under stones in coarse 
sand and gravel on the seashore at about the 1 or 2 foot tide level 
collected by R. E. Orth. In company with these specimens were 
adults of Diaulota harteri Moore, the only other staphylinid genus 
known from this habitat. 
Notes. The larvae of Bryothinusa can be distinguished from 
those of Diaulota , the only other staphylinid genus known from this 
habitat in southern California, by the presence of four small 
chitinized pigmented hooks with a bifid base imbedded in the apical 
membrane of the pseudopod. Specimens of larvae examined by us 
associated with adults of B. sawadai Moore et al., B. Hongkongen- 
sis Moore et al., B. sinensis Moore et al. and B. chani Moore and 
Legner all have pseudopodal hooks. Similar pseudopodal hooks 
have been reported in the larvae of Alianta incana Erickson by 
Paulian (1941). Paulian’s illustrations indicate they may be present 
in other genera.
