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 I 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.
