Imago .—“Head and thorax dark brown, clothed with mostly 
white hair; palpi brown, with brown hair; basal joints of anten¬ 
nas brown, beyond yellowish, narrowly annulate with brown at 
tips of joints; legs pale yellowish, first pair darker. Abdomen 
pale, sometimes darker on tip. Wings dusky, with sparse black 
hair; radius and cubitus dark brown; hind wings faintly dusky, 
with gray fringe. Both pairs are long, and acute at tips; fork 
3 much longer than fork 1, the latter very short pedicellate; 
lower branch of radial sector ending slightly before tip of wing. 
Expanse, 16 mm.” 
The above is the description of Banks. In the male the su¬ 
perior ( ?) appendages are slender, pointed, a little curved down¬ 
ward and inward, their tips nearly meeting. The dorsal por¬ 
tion of the last segment extends posteriorly beyond the ventral 
portion. Beneath the superior appendages the penis projects 
downward. The inferior appendages are very large, directed 
upward, the parts described above lying concealed between them. 
The basal portion of each is stout, in lateral view narrow; the 
distal portion is broadly expanded, oval, very hairy; in ventral 
view the inner edge of the basal portion is pectinate with spines 
and the last segment is excised medially. 
Larva. —Length, 7-8 mm. Width, barely 1 mm. at the 1st 
segment of the abdomen, % mm. at the 8th. Body in life 
bright green. Antenna? distinct, yellowish. Head and thorax 
yellowish with markings of dark brown. A median T-shaped 
mark on the upper part of the clypeus, the stem anterior; sur¬ 
rounding this in a long oval are six pairs of spots, all round 
except the posterior pair, which vary considerably in distinct¬ 
ness; on the anterior end of the clypeus are two pairs of short
