extremely long' white hair. Wings gray, veins yellowish, the sub- 

 costa and radius dark. Vein 8 emits two branches from above near 

 base, and then forks below, the branch running to middle of hind 

 margin; between this fork and vein 8 are four longitudinal veins, 

 the third a branch of the second, the fourth a branch of third (in 

 this respect nearer typical Palingenia). Vein 9 connected several 

 times to fork of 8; vein 9^ unconnected. Vein 6 forked plainly before 

 middle of wing, one long intercalary in this fork. Expanse 28 mm.

9 . Yellowish; a broad black band on face from eye to eye through 

 ocelli, facial carina with a black spot; pronotum and thorax with a 

 black stripe each side; a black stripe on each upper side of abdomen, 

 on the tip of each segment the stripe is broader than on base. Leg I 

 rather reddish, last tarsal joint blackish; other legs paler, tips of 

 femora and tibiae dark. Wings hyaline; most of veins yellowish, 

 subcosta and radius dark, cross-veins dark, some in base of fore 

 wings narrowly bordered; in hind wings the veins pale, cross-veins 

 dark, in discal part are about 16 or 18 cross-veins black, narrowly 

 bordered with white or hyaline, and outside of this a blackish fusi- 

 form mark, giving these veins a strikingly beautiful appearance. 

 Setse pale, some joints dark at tip. Expanse 44 mm.

 with a long dark U-mark each side, leaving a narrow median yellow 

 stripe, last segment pale above; venter pale, each seg-ment with a 

 dark streak or spot; tip of forceps dark; setse pale, tips of joints 

 dark; legs pale, claws dark; leg I more reddish, tip of tibia dark. 

 Tibia I of male almost twice as long as femur, tarsal joints one and 

 two subequal, third three-fourths of second, fourth about one-third 

 of third. Wings hardly hyaline, veins brown, apical costal area 

 red-brown, and the subcostal area to base also red-brown; the 

 costals in basal part of wing are margined; beyond middle of wing 

 are four dark spots, the outer three in a transverse row, the other, 

 larger, is on the forking of vein 6. Hind wings with tip and veins
