tibiae luteous, vestiture dense, yellow. Face silvery^ mystax 
black, vertex and occiput golden, hairs yellow; antennae elon- 
gate, black, third joint a little longer than the basal two together. 
Thorax coated with fulvous pollen, especially pronounced on 
posthumeral areas, scutellum black, lateral bristles of notum 
fine and yellow; meso- and sternopleurae largely polished. An- 
terior part of abdominal segments 2-4 sunken, pile of apical 
segments appressed, deep golden, becoming almost reddish 
beneath pygidium. Legs strong, hind femora robust, coxae, 
femora, tips of tibiae, and tarsi black, bristles of tibiae and tarsi 
reddish, pulvilli brown, claws black. Wings strongly and 
uniformly infumated, discal cell widened apically, anterior

Two specimens collected by Professor R. W. Doane at 
Pasadena, California, June 6, 1895. Type in collection of the 
State College of Washington. The dense pilosity and cons- 
tricted abdominal segments suggest Dicolonus, but the head is 
different, the vertex being deep-set and the face flat.
