of the submarginal vein closely ciliate, the remaining proximal part mostly 
naked, the marginal cilia of fore wing short and close, absent proximad on 
both margins; marginal vein abnormally broadened as in Pachyneuron 
Walker, conspicuous, about thrice the width of the postmarginal vein, short 
and broad, about the length of the stigmal vein and about a fourth shorter 
than the slender postmarginal vein; submarginal vein narrow, widening 
at distal sixth at its curve before joining the marginal vein and more 
than four times longer than the latter, much slenderer and bearing about 
fifteen large bristles from its surface; stigmal vein shorter than the post- 
marginal vein, straight, clavate, and with a small uncus, its knob or club 
distinct but not formed abruptly; postmarginal vein long and slender, uni- 
form in width, distinctly longer than either the marginal or stigmal veins, 
being about a fourth longer than either; marginal cilia of the costal margin 
of the wing beginning at the proximal end of the marginal vein; fore wing 
broadly rounded at the apex, the wing being widest at a point slightly 
distad of the end of the postmarginal vein; several spurious veins present. 
Hind wings uniformly, but not densely, ciliate on the disk, the submarginal 
vein extending to the hooklets; the costal cell irregular in shape, dilated 
in the middle, the submarginal vein consisting of a moderately broad proxi- 
mal half, confluent, or nearly, with the costal margin, then an abrupt nar- 
row portion not as long as the proximal thickened half and curving caudad 
away from the costal margin, the costal cell distinct and moderately broad 
at that point, and finally a third, short curved part distad, as broad as 
the proximal half and curved latero-cephalad to join the marginal 
vein at the hooklets and uniform in width with the marginal vein; sub- 
marginal vein about one and a half times longer than the marginal vein; 
posterior wings broadest at a point just distad of the apical end of the 
marginal vein, that is to say, a short distance distad of the proximal half 
of the wing; apex subacute; marginal cilia longer, sparser, longest on the 
caudal margin of the distal half or third of the wing. Tarsi 5-jointed, the 
tibial spurs all single. 
Antenne consisting of a scape, pedicel, three ring-joints, five funicle 
joints and three club joints; funicle and club hispid-pubescent, the flagel- 
lum regularly clavate, the club not abruptly formed or much larger or 
wider than the funicle. Scape long, cylindrical, slightly tapering distad, 
more than half the length of the flagellum and longer than the funicle, 
subequal in length to the united length of the pedicel, three ring-joints 
and the first three funicle joints; pedicel obconic, conspicuously longer than 
the third ring-joint and equal in length to it and the first funicle joint 
combined; the two proximal ring-joints distinct, equal, combined slightly 
longer than the third ring-joint, the latter abruptly smaller than the first 
funicle joint, a large ring-joint, nearly twice the size of either of the other 
ring-joints, and not bare like them, but only a third the length of the fol- 
lowing joint and about a fourth the length of the pedicel, wider than long; 
funicle joints cylindrical, but gradually becoming shorter, so that the
