Discussion. B. griseocollis is most closely related to £. morrisoni. Its females are readily recognized by the yellow hair on the pleura and black hair on metasomal tergite 3 (cf. Figs. 133, 134). Males can be distinguished from morrisoni by the apices of the penis valves, which are short, abrupt, and curved mesad but not recurved (cf. Figs. 35b, 36b). This species is rare in California and occurs prin-cipally in the northern transmontane area. Most of the flight and flower records are based on data from specimens collected outside the state. The biology of this species is discussed by Plath (1927, 1934) and Medler and Carney (1963). The perching habit of males is mentioned by Plath (1934). In southern Michigan, RWT observed males perching and darting out at approaching insects or small objects tossed near them and returning to their original perch.
