grayish pollinose, as viewed from behind, marked with four wide 
black vittz. Three postsutural and three sternopleural macro- 
chet. Scutellum black or reddish yellow at apex, densely 
gray pollinose, bearing three pairs of long marginal and a shorter 
cruciate apical pair of macrochete. Scutellar disk clothed with 
many fine long erect hairs and a pair of discal macrochetie. Legs 
black, knees yellowish, front pulvilli in male about as long as, in 
female one-half as long as, the last tarsal joint. Middle tibiz on 
the outer front side each, bearing several long macrochete, the 
hind tibiz with a row of stout bristles of irregular length. Abdo- 
men yellowish gray pollinose, marked with several distinct shining 
black reflecting spots and a median black vitta. First segment 
bearing a median marginal pair of marcochetee, second segment a 
median discal and marginal pair, third segment a median discal 
pair and a marginal row, and the fourth segment a discal and mar- 
ginal row. Fine, long, bristly hairs of abdomen sub-erect. Male 
hypopygium projecting, the genitalia curving forward beneath the 
fourth! abdominal segment, the tip of the forceps resting in a sheath 
formed by a bisected flap-like projection on either side of the me- 
dian venter of the fourth segment. Ventral aspects of forceps at 
base somewhat narrow, gradually broadening to their greatest 
width, whence they taper to a point at the tip. Inner margin of 
forceps on basal half, and the outer margin bearing bristly black 
hairs, the remaining surface shining brownish black with a few 
scattered black hairs. In the female the sheath of the ovipositor 
is similar in form to sheath of forceps in the male, but is not bi- 
sected on its front surface. The female ovipositor is not distinctly 
visible, but what appears to be this organ is shining black in color, 
broad at base and sharply pointed at tip. Wings longer than abdo- 
men, small cross-vein far before tip of first longitudinal vein, third 
longitudinal vein bearing two to six bristles at its base, posterior 
end of hind cross-vein nearer to bend of the fourth longitudinal 
vein than to the small cross-vein. Calypteres milky white.
