curvature at apex more decided than in oligoneura. Wings extend- 

 ing as far as tegmina, with apices similar except that the curvature 

 at the apex is slightly broader, these organs distinctively colored. 

 Cerci short, stout, apex acute, joints moderately moniliform. Ce- 

 phalic coxae with cephalic margin armed with (six) small, blunt, 

 irregularly placed teeth. Cephalic femora lamellate dorsad, the 

 dorsal margin evenly and weakly convex; ventro-internal margin 

 with spines arranged, as characteristic for the genus, in the following 

 formula, ilililililil I, all genicular lobes each armed with a short 

 heavy spine. Cephalic tibiae with eleven external and eleven and 

 twelve internal spines on the ventral margins. Median and caudal 

 femora dorso-distad each produced caudad in a longitudinal lamella, 

 only two-thirds as wide as tibia, the margin of which is broadly 

 convex. 



Head and pronotum cinnamon brown, the latter paling slightly 

 toward ochraceous-tawny dorsad. Tegmina subopaque, immacu- 

 late, strongly tinged with ecru-olive (probably much faded from 

 the color in life). Wings tinged with ochraceous-orange, this be- 

 coming ochraceous-tawny along costal margin distad in anterior 

 field. Cephalic limbs olive lake, the coxae and tibiae suffused with 

 brown, the femora showing traces of two pale transverse bands and 

 with the larger spines of the ventro-internal margins colored as the 

 other spines, the tips alone darkened. Caudal limbs olive lake, 

 the femora heavily suffused with blackish chestnut brown in prox- 

 imal and distal third and with traces of this color mesad, the tibiae 

 annulate proximad, mesad and distad with this color, the tarsal 

 joints suffused distad. (The ground color of the limbs is apparently 

 much faded from the color in life.) 



Length of body 19.2, length of pronotum 5.9, greatest width of 

 pronotum 2.6, width of pronotal shaft 1.6, length of tegmen 12.3, 

 width of tegmen 4.4, width of tegminal marginal field 1.1, length of 

 cephalic femur 5.8, width of cephalic femur 1.9, height of lamella 

 on caudal femur .4, length of caudal femur 4.9 mm. 



The type of this extraordinary little mantid is unique.
