Operculum subelliptical, about three-fourths as long as wide, and 
not quite one-half length of orifice. Lingula about five-sixths length 
of orifice, the distal two-fifths somewhat enlarged, and arrow-shaped, 
thickly setose, and terminating in two straight setze, which reach quite 
to caudal end of orifice. Rudimentary feet on ventral surface quite 
distinct. 
Adult 2 .—Length, about 0.74 mm.; fore-wing, 0.846 by 0.35 mm., 
hind tibia, 0.832 mm.; hind tarsus, 0.17 mm.; color, bright yellow, 
abdomen paler, with a deep reddish-orange spot, due to visceral gland; 
legs and antennz pale yellow. Wings immaculate. Eyes undivided, 
but somewhat constricted above the middle; dark brownish-red in 
color. Mentum usual; first joint, long, slender, widening gradually 
distad; second joint, short, thick, about one-third length of distal joint; 
distal joint, stout, gradually tapering from second joint to the blunt, 
brownish-colored point. Fore-tibia, six-elevenths length of hind-tibia; 
middle tarsus, four-fifths length of hind tarsus. 
Vasiform orifice triangular. Operculum, when elevated and seen 
in lateral aspect, bluntly conical, and the caudal margin appears 
minutely setose. Lingula long, subcylindrical, tapering abruptly to 
an acute point; slightly curved, the convexity cephalad. Lingula 
apparently somewhat serrate, due doubtless to obscure sete. In fore- 
wing, main vein nearer cephalic than caudal margin, extending distally 
about eight-ninths length of wing. Basal veinlet arising at very base 
of wing, apparently distinct from main vein, and extending obliquely 
caudad to margin of wing. Genitalia ordinary.
