ulnar vein with three almost parallel rami, stigma distinct. Wings 

 exceeding the tegmina by about a third the length of the pronotum, 

 slightly longer than twice the width; costal margin nearly straight, 

 apex rather narrowly rounded. Cephalic coxse slightly less than half 

 the length of pronotum, not armed ; cephalic femora about five-eighths 

 the length of the pronotum, the ventro-caudal margin bearing four 

 large and one small distal spines, the ventro-cephalic margin armed 

 with two grades of spines, the larger size numbering six and the smaller 

 eight, the smaller being placed one each between the larger spines, 

 except that distad of the distal large spine two small ones are present 

 and between the first and second distal spines three are present, dis- 

 coidal spines four in number; cephalic tibiee (exclusive of terminal 

 claw) less than a third the femoral length, the cephalic margin with 

 sixteen spines increasing in size distad, caudal margin with five spines; 

 tarsi about equal to the tibiae in length. Median and caudal limbs 

 very slender but not greatly elongate, the caudal femora not quite 

 reaching the middle of the third abdominal segment. 



General color Prout's brown. Tegmina hyaline washed narrowly 

 along the sutiu-al margin (distad of the dividing vein) and very broadly 

 along the costal margin with Prout's brown, the greater portion of all 

 the longitudinal veins being marked with numerous fine linear seal 

 brown touches. Wings with proximal half hyaline, the apex of the 

 anterior field yellowish coriaceous, the remainder vandyke brown with 

 very strong violet reflections, this coloration also extending nearly to 

 the base as a varying line along the mediastine vein, the caudal section 

 of the broad transverse bar extending clear to the margin, and broken 

 only by less infuscate areas immediately surrounding the radiate veins 

 and the clear pattern of the transverse veins. 



? . Head much as in the male, facial scutellum slightly less arcuate ; 

 antennse very short, hardly exceeding the length of the collar of the 

 pronotum, filiform. Pronotum with the collar nearly a fifth the length 

 of the whole pronotum, coxal dilation slight; collar slightly tapering 

 cephalad, the cephalic angle narrowly rounded and with an apparent 

 elevation caused by a marked depression of the collar immediately cau- 

 dad ; lateral margins of the collar dentate, shaft with the margins un- 

 armed; median carina distinct on the collar and on the cephalic and 

 caudal sections of the shaft, collar trigonal in cross section, shaft rounded 

 dorsad. Tegmina about a fifth the length of the pronotum, reaching in 

 repose to about the middle of the first abdominal segment, margins very 

 slightly approximate distad; apex broadly rounded, stigma distinct. 

 Wings in repose extending beyond the tegmina by not quite a third
