tiiberance longitudinal; rounded. Wings almost twice the length of 

 the tegmina; costal and discoidal regions coriaceous and subreticulate 

 as in the tegmina. Abdomen with the segments distinctly longitudinal ; 

 sixth dorsal segment some^^'hat expanded; seventh segment com- 

 pressed, almost equal to the sixth in length; eighth and ninth segments 

 subequal in length and width, together but slightly longer than the 

 seventh segment, the ninth carinatc and with the apex sinuate ; supra- 

 anal plate small, transverse, subtriangular, not half the length of the 

 ninth dorsal segment; cerci short, conoid, not as long as the supra-anal 

 plate; subgenital plate cyml^iform, carinate, elongate, exceeding the 

 apex of the supra-anal plate by the length of the fifth and sixth abdomi- 

 nal segments, apex narrowly rounded. Anterior femora three-fourths 

 the leng-th of the mesonotum, basal flexure sharp; tibise slightly longer 

 than the femora; metatarsi somewhat shorter than the remaining tar- 

 sal joints. Median femora equal to the anterior femora in leng-th. 

 inferior surface with three spines on the apical portion of the mediai: 

 line, the anterior and posterior margins each apically with a single 

 spine; tibia? about equal to the femora in length; metatarsi hardly 

 more than half the leng-th of the remaining tarsal joints. Posterior 

 femora exceeding the other femora and equal to the first, second and 

 half of the third basal abdominal segments in length, anterior inferior 

 margin with two apical spines, median line of the inferior surface witl> 

 three spines, posterior inferior margin with a single apical spine; tibia- 

 slightly exceeding the femora in length; metatarsi but slightly shorter 

 than the remaining tarsal joints. 



General color (from spirits) vinaceous brown, metathorax with thi 

 pleura bearing a longitudinal whitish bar, a style of coloration alsr<
