POLYCHITONACRIS ATAVA (Saussure). 



1859. P[olysareus] atavus Saussure, Revue et Magasin de Zoologie, 2me eer., 

 XI, p. 393. [Bahia, Brazil.] 



Minas Geraes, Brazil. [Ilebard collection.] One female. 



Rio de Janeiro Brazil. November. (H. H. Smith.) Two 

 females. 



The Minas Geraes specimen is somewhat smaller than the Rio de 

 Janeiro individuals, and has the second pronotal lobe not quite as 

 distinctly separated from the third or the spine at the apex of the 

 caudal femora as long. The size of all the individuals is greater 

 than the original measurement given by Saussure ("Long., 0.022"), 

 but otherwise they do not appear separable from true atava. 



The measurements are as follows: 



Length of body (including ovipositor jaws) . 



Length of pronotum 



Greatest width of dorsum of pronotum 



Length of caudal femur
