One male from Las Juntas, Department of Santa Cruz, and one 

 female from the Province del Sara, Bolivia, are referred to Scudder's 

 species. The former was collected in December and the latter in 

 either March or April of the same year. In addition there are two 

 rather young nymphs, which also seem likely to belong here. The 

 latter come from Las Juntas, in the Department of Santa Cruz. 

 They, together with the male, are part of C. M. Ace. No. 5060; 

 while the female belongs to C. M. Ace. No. 5058. They were all 

 taken by J. Steinbach. 



The young nymphs have the median pronotal carina greatly arched 

 and deeply notched.
