wide; 4 much shorter than 3, about twice as long as wide, sides broadly 
rounded in basal fourth, nearly straight beyond; 5-8 more or less barrel 
shaped, with sense cones, 5 narrowed at base; 9 about three times as 
long as wide, obliquely truncate at base, its axis tipped more or less 
outward from that of rest of antenna; segment 1 slightly lighter than 
head, 2 about concolorous with it, very slightly, if at all, paler at apex; 
3 and 4 pale yellowish, with orange pigment apically, 3 narrowly and 4 
widely, darkened with gray at apex; 5-9 grayish brown, 5 paler sub- 
basally. 
Prothorax about 1.4 times as long as head and about 1.6 times as 
wide as long, broader behind, sides and posterior margin rounded, an- 
terior margin nearly straight; notum with a few inconspicuous bristles, 
its surface closely transversely striate with anastomosing lines. Wings 
of fore pair nearly half as wide at middle as near base, the greatest 
sub-basal width (exclusive of scale), about one-ninth the length of 
wing; costal margin, anterior vein, and posterior vein with about 30, 
26, and 16 spines, respectively. 
Abdomen stout, pubescence dense, disposed on close, anastomosing 
striae; posterior margins of abdominal tergites 1-5 fringed at sides 
with numerous slender spines which are not at all coalesced at base to 
form plates or scales; tergites 6-8 and sternites 2-6 with their entire 
posterior margins similarly produced.
