and the fourth one-half longer and more slender than the third; 
face reddish brown, eyes black. Mesonotum dark brown, the 
submedian lines indistinct. Scutellum reddish yellow, postscutellum 
reddish brown. Abdomen light reddish 
brown, rather thickly clothed with pale 
setae and _ slightly fuscous distally. 
Wings hyaline, costa yellowish brown, 
the third vein joining the margin well 
beyond the apex; halteres yellowish 
basally, semi-transparent apically. Legs 
a nearly uniform dark brown; claws 
(fig. 22) long, slender, evenly curved, Fig. 22 Metadiplosis spin- 
simple, the pulvilli about one-third the  osa, claw (enlarged, original) 
length of the claws. Genitalia; basal 
clasp segment short, stout, truncate and at each internal distal angle 
a long, stout, chitinous spine; terminal clasp segment short, greatly 
constricted near the middle, enormously swollen and recurved 
apically; dorsal plate short, broad, deeply and rather narrowly

This genus is erected for a species remarkable because of the 
enormously produced, curved, setose-bearing spine on the basal 
clasp segment, this peculiar organ being nearly as long as the ter- 
minal clasp segment and strongly suggesting the genitalic modifica- 
tion we find in Lobodiplosis. It is, however, readily separable from 
this last named genus by the simple claws.
