siibeqiial in width, tectate, the seventh ahiiost equal to the other two in 

 length, apical margin with the median portion truncate; supra-anal 

 plate moderately produced, truncate,, rounded; cerci very short, hardly 

 visible ; subgenital opercule equal to the apex of the supra-anal plate 

 in length, compressed, keeled, the posterior portion of the carina 

 irregularly dentate. Anterior femora slightly shorter than the meso- 

 notum in length, compressed, the superior margin considerably ex- 

 panded basally and undulate, inferior external margin apically with 

 two distinct teeth, external genicular lobes acute ; anterior tibiae about 

 equal in length to the femora, compressed, the superior margin with a 

 continuous foliaceous expansion which develops a slight premedian 

 lobe; metatarsi ecjual in length to the remaining tarsal joint, superiorly 

 with a foliaceous expansion equal in height to that on the tibiae ; fifth 

 tarsal joint almost equal in length to the second to fourth inclusive. 

 Median femora equal to the metanotum (with median segment) in 

 length, slightly compressed, the internal inferior margin armed apically 

 with two dentiform processes, external genicular lobes acute ; median 

 tibiae shorter than the femora and equal to the fifth and sixth abdomi- 

 nal segments in length, inferior median carina with a low basal expan- 

 sion/the superior carina with an apical bullate expansion of about equal 

 height; metatarsi not equal to the length of the remaining joints, 

 without any foliaceous expansion; fifth tarsal joint shorter than the 

 second to fourth inchisive. Posterior femora not quite reaching the 

 middle of the third abdominal segment, moderately compressed, sul- 

 cate above, internal genicular lobes acute, lateral inferior margins 

 armed apically with two spines, those on the internal margin prominent ; 

 posterior tibiae exceeding the femora and almost equal to the meso- 

 notum in length, median inferior carina with a low elongate foliaceous 

 expansion at the extreme base, apex with a bullate expansion similar 

 to the median tibiae; metatarsi about equal to the remaining tarsal 

 joints in length, fifth tarsal joint equal to the second and third in 

 length. 



General color wood-brown, finely flecked with blackish, becoming 

 semi-ochraceous on the anterior limbs and antennae, the latter with 

 regiilarly disposed, usually incomplete annuli of blackish.
