Graptomyza setigloba n. sp. (Plate 10, Fig. 10) 
Male. Length 6.5 mm. 
Head: vertex and front polished, vitreus blue black, the 
latter with a semicircular crease or depression on each side, 
the convex edge of which it turned to the mid-line. Just 
above the antennae the face, also vitreus, becomes light- 
brownish yellow and this is the color of all the remainder of 
the face and cheeks. Face descending into a long pointed 
cone, covered with a very few long pale bristles. Pile of 
occiput and front pale ; of the vertex black. Eyes with very 
sparse pale pile. Antennae, except for a narrow dorsal black 
band, entirely brownish yellow to yellowish orange outward- 
ly. Arista long and slender, pale colored, ten rayed, the 
rays on the outer half only. The third joint is very long 
and broad and flat. It is pendulous and practically descends 
to the lowest level of the eyes. The apical bristles of second 
and third joints black. Occiput excavated, its margin not 
visible from lateral profile. Thorax: shining bluish black on 
the central dorsum, the humeri, suture, calli and the scutel- 
lum, except its brown central ellipsoidal depression, all shin- 
ing clay yellow or brown. Pile of thorax and scutellum pale 
brassy, the bristles black. Abdomen: pale subtranslucent 
yellowish brown, marked with black. On the posterior 
border of the second segment there is a black triangle, the 
base on the border, the three angles of which are extended 
somewhat as narrow lines, the two antero-lateral faces of 
the triangle quite concave. Third and fourth segments 
largely black, the narrow anterior portions of these seg- 
ments pale and the black of the third segment nearly meet- 
ing the second segment medially, but obtusely rounded off. 
The lateral margins of second, third and fourth segments 
narrowly black. Whole abdomen unusually globose. The 
bristles thick, semi-decumbent and black in color. Some 
short, pale pile on the basal half of second, third and fourth 
segments and the ventrally directed lateral fringe of pile 
is pale. Legs: brown, the femora and tibise pale yellowish
