caudal margin broadly sinuato-arcuate over the greater portion of its width; 

 supra-anal plate transverse, subquadrate, distal margin subarcuato-truncate, 

 caudo-lateral angles obtuse rounded, lateral margins convergent caudad, con- 

 cave; cerci depressed, styliform, blunted; subgenital plate transverse, distal 

 margin bisarcuate, deeply and narrowly arcuato-emarginate at the insertion 

 of the styles, the latter elongate, simple, tapering. Limbs robust, rather short; 

 cephalic femora with ventro-cephalic margin bearing a series of spines of irreg- 

 ular length on distal two-thirds, distal extremity of cephalic face with a pair 

 of strong spines, no dorsal genicular spine, ventro-caudal margin with four 

 spines on distal half, distal one of the series slightly the larger; median and 

 caudal femora each with a dorsal genicular spine and all ventral margins well 

 armed; all tibiae with spines triseriate on dorsal face, median and caudal tibiae 

 strongly compressed; caudal metatarsi very short, other caudal tarsal joints 

 missing. 



Color shining black; antennae black proximad, passing at proximal third into 

 ferruginous. 



Length of body, 33.5 mm.; length of pronotum, 9.5; greatest width of 

 pronotum, 13.4; length of tegmen, 5.4; greatest width of tegmen, 3.7; length

 Provisionally, at least, we are using peruajia for this species. 

 The specific names in the genus Panchlora are greatly involved in 

 uncertaint}', due to the variability of the species themselves and 

 the failure of the older, and for that matter some of the more re- 

 cent, authors to mention the important genital features of their 

 species.
