the length of the latter, the length but slightly greater than the 

 length of the tegmen. Abdomen with the apex broad, depressed, 

 the three terminal segments with very distinct median longitudinal 

 marginal folds; supra-anal plate about as long as broad, the distal 

 portion rounded; cerci broad, lamellate and truncate as usual in the 

 genus; subgenital plate strongly compressed, rostrate, diverted ven- 

 trad out of the general abdominal plane. Cephalic coxae slightly 

 less than half the length of the pronotum, slightly armed, distal section 

 expanded and compressed, being abruptly trigonal in section, while 

 the proximal three-fom-ths is transverse in section; cephalic femora 

 slightly more than half the length of the pronotum, the margins armed 

 as in the male except that the cephalic margin has one or tw6 

 additional spines of the second order; tibiae and tarsi as in the male. 

 Median and caudal limbs slender but not greatly elongate. 



General color tawny-olive finely washed, spotted and sprinkled with 

 Front's brown; eyes marked with seal brown. Pronotum with the 

 two colors showing very distinctly in a pattern which is pardaline in 

 ■character, the shaft with its cephalic fifth inclined toward bistre. 

 Tegraina tawny-olive in the proximal half, becoming brick red in the 

 distal half, the costal section Front's brown, some of the rami of the 

 ulnar vein and the dividing vein with short fine linear touches of bistre, 

 the folded proximal section blackish purple. Wings with the anterior 

 field broccoli brown, yellowish along the costal margin and rich brick 

 red in the distal third ; posterior field with the base color purplish brown 

 with a very strong purplish-blue sheen, bearing two irregular maculations 

 of lemon yellow, limited to about the cephalic half of the field and each 

 bearing distad an area of equal size of the clear base color of the area, the 

 whole wing except these areas and the semi-coriaceous red section of 

 the anterior field having all the transverse veins white or yellowish- 

 white. Abdomen of the general color; limbs of the general color with 

 the pardaline appearance distinctly marked on the median and caudal 

 limbs.
