 Costa beaiing 27 to 28 regularly placed, though somewhat closer on 

 basal than on outer half. Fore vein on basal two-fifths bears seven 

 to eight spines, and scattered beyond the center three other spines, of 

 which the last one stands near the tip. The other two spines may 

 stand close together near the second tliii-d of the wing, or the second 

 one may stand equidistant from the first spine and from the spine 

 at the tip. Hind vein bears 11 to 15 spines regularly placed; scale 

 bears five spines and interior of scale one. Front fringe long and a 

 little tliicker than the spines. Hind frmge rather thick, long and 

 wavy, light brown. Front fringe intemiediate in color between the 

 spines and the liind fringe. Hind wing gray, with a single median 

 vein disappearing just before the tip; front fringe slender, sparse,

 and middle tibisB stout. All tarsi with dark-brown spot at tip 

 within. Two stout pale-yellow spines at tips of hind tibise witliin; 

 a row of eight to ten much smaller spines on inner side of hind tibia. 

 Spines at tips of other tibiae small and inconspicuous. All femora and 

 tibiae clothed with numerous short, slender, pale-yellow spines. 



Abdomen cyhndrical ovate, blunt at apex; a heavy dark-brown 

 stripe across dorsum of segments 2 to 8 near then- anterior edges. 

 Sides of abdomen faintly striate. Each segment 2 to 8 laterally 

 bears three to four small dark brown spines. Ninth segment bears 

 a circlet of 10 medium-sized spines. Tenth segment bears a circlet 

 of six similar spines. Tenth segment split open above for a little 

 more than half its length. In the lighter specimens abdomen is 

 dark brown at the tip.
