apical white band, costa bears 28 to 31; fore vein 17 to 18; hind vein 

 14 to 16; scale 6, interior of scale 1 ; a light sparse fringe on costa of 

 each wing, posterior fringes heavy and wavy. The single median

 except distal half of fore tibiae which shade to yellowish-brown; all 

 tarsi pale yellowish-brown; base of bladder with a dark brown spot. 

 Fore femora thickened. All legs clothed with numerous small, light

 at the tips within, also a row of four smaller spines along the inner 

 margin. Fore tibia bears two conspicuous teeth at the tip within, 

 the outer one being much the stronger and longer, the inner one is 

 more blimt and bears a slender spine near the tip. 



Abdomen rather stout to the eighth segment, thence narrowing 

 abruptly to the tip; a dark brown narrow stripe across the dorsum 

 of segments two to eight near theii* anterior edges ; a row of six short 

 slender spines on posterior margin of ventral segments two to seven ; 

 two or three spines on sides of segments two to seven only one of 

 which is prominent ; three prominent spines on each side of segment 

 eight. Segment nine near its posterior margin bears a circlet of 10 

 spines of which the dorsal six are long and prominent. Tenth seg- 

 ment near the tip bears a circlet of six spines of which the dorsal 

 four are long, slender, and conspicuous. The tenth segment also bears
