tudinal; third vein bristly; costal spine vestigial; section III of costa 
almost equal to section V; alulae fringed with short hairs; calyjjtcrs 
whitish, outwardly fringril with white iiairs. 
Legs. — Dark; posterior trochanter with ' brush'; femur cylindri- 
cal, often slightly arched, clothed beneath with long hair; anterior 
face with two complete rows of bristles, an upper and an intermediate, 
bristles of latter very long and stout; usually bristles of lower row 
retained on distal half, but widely separated; posterior face of fenmr, 
also of tibia, with a i)eard of long, coarse hairs; anterior face of tibia 
with a similar beard of shorter, less dense hairs on its distal three 
fourths; tibia generally slightly curved, but straight in small speci- 
mens; tarsus shorter than tibia. Middle coxa with a single row of 
bristles; femur with long fine hair on its posterior ventral surface, 
especially proximally; submesotibial bristles present. Anterior coxa 
with twD rows of l)ristles.

and hair-like; scutellar apicals present; three sternopleurals. 
Abdomen. — Elliptical in outline; ventral parts of fourth notum 
often nearly the color of genital segments. In profile fourth ventral

Genital segments. — Wiien in normal position so held that ven- 
tral parts of fourth notum are spread apart and downward: first seg- 
ment either dull orange throughout, or anterior part grayish pollinose 
or brownish even nearly back to marginal bristles; sparingly yellow 
pollinose centrally; vestiture short; in profile with a shallow depres- 
sion anterior to bristles; second, dull orange, shape somewhat variable, 
but posterior surface flattened; anal area prolonged upward practi- 
cally to limit of posterior surface. Forceps very short, usually greater 
part visible, base with short upward flap-like extensions that bear 
long, fine, curly hairs.
