108 PSYCHE [October 
Normal position. 
Female: Length, 1.0 mm., average; moderate for the subfamily; visible to 
naked eye. 
General color pallid lemon yellow, uniform; apical tarsal joint dusky; venation 
concolorous; legs and antennae pallid, with some silvery; wings hyaline, with the 
exception in the fore wing of a minute, but distinct, usually ovate but variable, 
fumated spot or dot projecting caudad (and slightly proximad) from the caudal 
apex of the stigmal vein, and embracing its knob. Abdomen with three conspicu- 
ous dusky bands encircling its center, all interrupted at the meson dorsad, the inter- 
ruption broadest in the cephalic band, the caudal band of the three not very widely 
interrupted; these bands are along the caudal margins of the 4th, 5th and 6th abdomi- 
nal segments and are less distinct ventrad. Ocelli and eyes deep red; mandibles 
fuscous. 
Body impunctate, the vertex and dorsal aspect of the thorax delicately longi- 
tudinally striate, the abdomen showing distinct polygonal reticulation, which gives 
the appearance of longitudinal striation and scaliness. ‘The striation of the vertex 
and thorax is fine. 
Fore wings mostly without discal cilia, excepting in the apical fourth where 
they are not dense; the ciliate area is irregular, extending proximad to a point oppo- 
site the proximal end of the marginal vein in the caudal third of the wing, not near the 
caudal margin, in a line of paired setae, and again farther cephalad, spreading irregu- 
larly to the knob of the stigmal vein; there are also one or two scattered setae proxi- 
mad of the stigmal knob, caudad of the marginal vein; discal cilia not arranged in 
regular rows. Apex of fore wing regularly, symmetrically rounded, the postmarginal 
vein absent, the stigmal vein short, thickened distad to form a triangular knob, the 
apex of which is obliquely truncate; stigmal vein forming a curved continuation of 
the marginal vein, the angle formed by them obtuse; marginal and submarginal 
veins Jong, subequal, the former thicker. Marginal cilia of the fore wing longest 
distad, the longest cilia not more than two-thirds the greatest width of the wing, 
which is at the distal fourth distant from the venation. Body of hind wing linear, 
with one principal longitudinal row of discal cilia, excluding the single row near the 
cephalic margin running along the bases or insertions of the marginal cilia; the usual 
row of discal cilia near the caudal wing margin obsolete. Marginal cilia of the 
cephalic margin of the hind wing short and delicate, but distinct, those of the caudal 
margin long and strong, about equal in size to the largest marginal cilia of the fore 
wing and distinctly twice longer than the greatest width of the hind wings. 
Eyes coarse; ocelli in an acute-angled triangle in the center of the vertex, dis-
