nearly so, the costal region light yellow, the stigma a little darker 
brown; a broad vitreous band before the stigma, along the cord 
and into cell 1st Mo; a vitreous blotch beyond the stigma occupying 
most of cell Snd Ri. Venation as in Plate XVI, fig. 14. 
Abdomen dull yellow without distinct stripes, the caudal margin 
of the tergites three to eight broadly margined with silvery; hypo- 
pygium reddish. Male genitalia with the eighth tergite rather broad, 
the margin being straight; ninth tergite (see Plate XIX, fig. 52) 
large, the caudal margin with a deep U-shaped notch which bears 
a small rounded median lobe beneath; the dorsal surface bears a 
broad median groove or depression to the base; the lateral lobes 
are broad, directed caudad, the tip a cylindrical chitinized point 
which is directed ventrad and slightly inward. Ninth pleurite 
(see Plate XVIII, fig. 35) large, prominent, oval, convex, not in 
contact with the ninth tergite; appendages two: outer appendage 
a long, cylindrical, fleshy lobe, subsigmoid, pale, covered with long 
divergent hairs; inner appendage complex (see Plate XX, fig. 69), 
composed of a caudal lobe which is directed backward, pointed, 
and a cephalic lobe which is compressed, black and heavily chitinized 
along the margin; on the outer face of this blade is a conspicuous 
membrane which is provided with numerous hair-like ribs. Ninth 
sternite extensive, convex, very deeply notched beneath and with 
a pair of very short fleshy lobes which bear dense tufts of long yellow 
hairs, each decussate with the tuft of the opposite side. Eighth 
sternite (see Plate XVII, fig. 26) large, prominent, projecting caudad, 
the posterior margin with a rounded notch which bears a dense tuft
