Size small; form ovoid; apex anteriorly depressed; surface pol- 

 ished. Head projecting very slighth' bej'ond the pronotum; the 

 interspace between the eyes considerably greater than that between 

 the ocelli; eyes reniform. Pronotum with the greatest width jDoste- 

 riorly; anterior margin narrow, truncate; posterior margin sub- 

 truncate, three times the width of the anterior margin; lateral margin 

 arcuate, anterior angles well rounded, posterior angles narrowly 

 rounded. Abdomen strongly depressed, each segment of the lateral 

 margin slightly projecting posteriori}^; ventral segments, except the 

 two apical ones, bearing evenly distributed longitudinal folds, which 

 extend about the whole depth of the segment. Supra-anal plate 

 transverse, very slightly produced, apex very slightly and yqyj shal- 

 lowly emarginate. Cerei fusiform, very slightly depressed, the apex 

 acuminate, supplied with long stitf bristles. Subgenital plate not 

 prominent, the apical margin slightly produced, truncate; styles 

 unequal, one stout and acuminate, the other minute. Anterior femora 

 with twelve spines on the anterior margin, restricted to the median 

 and distal portions, the proximal two and apical two the largest 

 in the series; posterior margin with live spines restricted to the 

 median and distal portions, no genicular spine; tibia3 two-thirds the 

 length of the femora; tarsi equal to the femora in length. Median 

 femora with six spines on each margin, genicular spine slender; 

 tibiae about equal to the femora in length; tarsi shorter than the 

 tibiae, the metatarsi equal to the other joints in length. Posterior 

 femora with six spines on each margin, genicular spine slender and 

 about equal in length to the apical spine on the anterior margin; 

 tibiae slightly exceeding- the femora in length; tarsi about two-thirds 

 the length of the tibia% metatarsi about equal to the remaining tarsal 

 joints in length, arolia rather small. 



General color whitish gra}'. mottled and sprinkled with blacki 

 Head with the lower surface evenl}^ sprinkled with spots of dark 

 brown, interspace between the eyes with three longitudinal streaks 

 of brown; eyes mahogan}" brown. Pronotum heavily blotched cen- 

 trall}" with black, the overlying tint forming distinct spots as the 

 lateral margins are approached, and also decreasing in size; median 

 portion of the pronotum bearing two longitudinal streaks of whitish 

 gray. Mesonotum and metanotum with a color pattern very similar 

 to that of the pronotum, except for the absence of spots on the lateral 

 portions and the infuscation of the posterior margin. Abdomen with 

 the basic tint black, the folds of the segments and the apical portions 

 of the two terminal segments dull grayish; ventral surface of the 

 abdomen blackish centrally, blackish and grayish marmorate laterally. 

 Cerci grayish, a touch of l)lack on the basal jiortion of the upper 

 surf a("e. Limbs yellowish gray, each longitudinal marked with a single
