supra-anal plate; very brief margin between styles rather sharply concave, from 

 which springs, beneath the sinistral portion of the base of the dextral style, 

 a slender chitinous shaft, slightly less than half as long as the style, bearing five 

 slender elongate teeth, four along dextral margin directed disto-dextrad and one 

 at apex directed distad.

Agrees rather closely with male. Form slightly broader, tegmina distinctly 

 shorter, only slightly surpassing cereal apices.'" Interocular space broader, fully 

 one and one-third times occipital ocular depth, three-quarters the width between 

 the antennal sockets. Dorsal surface of abdomen not specialized. Supra-anal 

 and subgenital plates as described for the female of gemmicula.

Head dull ochraceous-orange, with two narrow bands of ochraceous-buff be- 

 tween the eyes, of equal width, separated by a slightly narrower interval of the 

 general coloration, the lower band continued narrowly for a brief distance along the 

 ventral margin of the eyes, as in translucida. Proximal antennal joint of general 

 coloration washed with darker brown, succeeding joints in proximal third of anten- 

 nae mummy brown, shading gradually to remaining portions which are ochraceous- 

 buff. Pronotum with disk tawny, pronotum very narrowly margined for a brief 

 distance meso-cephalad and along the entire caudal margin with whitish, '"^ lateral 

 portions transparent, very faintly tinged with buckthorn brown. Tegmina with 

 marginal field and half of costal field toward costal margin transparent, very faintly 

 tinged with buckthorn brown, remaining portions rather strongly tinged with buck- 

 thorn brown, the numerous veins very faintly tinged with that color, except the 

 humeral trunk which is suffused with prout's brown. Wings transparent; radiate 

 field to axillary vein tinged with munun\- brown, remaining portions tinged with 

 ochraceous-buff, approaching ochraceous-tawny in area of branches of axillary 



'"'The small series shows that some variation in size and considerable variation in 

 tegmina] length occurs in the present species. In view of the fad that the two females 

 of the closely related gemmicula show less tegminal reduction, we would expect to find 

 females of the present species with tegmina of greater length, as well as the condition 

 shown by the single female at hand.
