long proboscis, reflexed anal vein, and distinct fold under the humeral crossvein at the origin of the 
second basal cell do not indicate close kinship to the Clinoceratinz.

Characters. — Small dark-colored rare species of generalized structure. Eyes of the male 
subcontiguous above the antenne, separated only by a line, the facets uniform and bare, of the female 
broadly separated on the short front, female with two small fronto-orbitals, face very short and broad, 
the large quadrate epistome receding, cheeks linear; antenne short, basal joints minute and globular, 
third joint long and conical, style very thick, nearly half as long as the third joint, its basal segment four 
times aslong as broad and tipped with a short bristle; proboscis short and chitinized, the labrum incurved, 
broad at the base and pointed, palpi very short, retracted, horizontal. "Thoracic bristles short, one hume- 
ral, three posthumeral. about eleven dorsocentral and three notopleural, but the scutellum with six 
strong bristles; pleurze bare. Abdomen twice as long as the thorax, tapering in the female and tipped 
with two long styles, in the male with a terminal small open pygidium which bears a pair of lateral slen- 
der curved pointed valves and a pair of erect dorsal processes. Legs simple, bristleless, hairs sparse and 
inconspicuous. Wings broad, anal angle strong, no axillar excision, costa enclosing the entire wing, 
no humeral bristle, auxiliary vein distinct, complete and ending by a gentle curve in the costa, fork of 
the third vein long, contact of the discal cell with the third posterior cell longer than with the fourth, 
anal crossvein reflexed, anal vein continuous with the under side of the anal cell.

(1) Brochella monticola, nov. sp. (PI. 2, Fig. 16). — Male. Length 4.5 mm. Black in groundcolor, heavily 
pruinose or pollinose. Front brown, face gray, proboscis silvery white, occiput brownish gray. Notum brownish gray 
becoming brown on dorsocentral rows, scutellum, pleure and abdomen cinereous; pygidial valves hairy. Wings uniformly 
infumated, veins brown, no stigma, a crossvein near basal third of discal cell. 
Female. Hind femora less robust than in male, the tibize without umbo or fringe at apex. 
Types Seventeen males, seven females, found by the writer along the rills above Paradise Park on Mt. Rainier, 
Washington, during the middle of August, 1917. A visit to the same locality in the latter part of August of the same year 
and again in July, 1922, failed to disclose additional specimens, although special effort was made to discover them.
