distinctly emarginate apically ; discoidal area \Yith the tubercles com- 

 pressed, longitudinal, triangular in outline. Wings ample, reaching to 

 the apex of the abdomen in repose, almost twice as long as broad; apex 

 rather narrowly rounded. Abdomen with the six basal segments longi- 

 tudinal, decreasing in size toward the apex; seventh and eighth dorsal 

 segments each about three-fourths the length of the sixth segment, tec- 

 tate; ninth segment tectate, slightly shorter than the preceding segment, 

 apex obtuse wdth a slight median emargination exposing the triangular 

 apex of the supra-anal plate ; cerci slender, simple, extending but a slight 

 distance beyond the tip of the ninth segment; subgenital opercule large, 

 cymbiform, extending to the apex of the ninth dorsal segment, apex 

 produced, rectangulate. Limbs moderately slender. Anterior femora 

 injured; tibiae somewhat shorter than the thorax; metatarsi shorter 

 than the remaining tarsal joints. Median femora equal to the meso- 

 thorax and metathorax in length; tibiae distinctly shorter than the 

 femora ; metatarsi about two-thirds the length of the remaining tarsal 

 joints. Posterior femora equal to the four basal segments of the 

 abdomen; tibiae equal to the femora in length; metatarsi equal to the 

 remaining tarsal joints in length. 



General color dull black, becoming brownish-black on the abdomen 

 and limbs; mesonotum, mesopleura, mesosternum, metapleura and 

 metasternum with several obscure lines of dull ochraceous. Femora 

 each with several very obscure annuli of dull ochraceous. Tegmina 

 ochre-yellow, suffused on the apical portion of the discoidal and pos- 

 terior fields with pale glaucous-green; longitudinal veins of the dis- 

 coidal and posterior fields apically, and the posterior margin entirely 

 lined with black. Wings with the costal and discoidal regions pale 

 ochre-yellow, fading into pale glaucous-green apically ; anterior margin, 

 a spot before the base and the veins of the discoidal area blackish; 

 posterior field with the disk very pale clay color, the periphery and 

 apex dark smoky-hj-aline.
