vided with 8 spines in outer and 10 in inner row, the inner apical spurs 

 considerably stronger than the outer ones, unequal. Interspace

Habitat . — The collection made by W. T. Foster at Sapucay, Para- 

 guay, contains two females. 



PLECTROTETTIX McNeill. 



This genus contains a number of species, the representatives of which 

 vary much in color. At least five of the known forms occur in Para- 

 guay.'* These Paraguayan forms may be separated by the following 

 table: 



TABLE FOR DETERMINATION OF SPECIES. 



o. Tegmina less densely reticulate, the post-radial area provided with two rows of 

 cells and an intercalary vein; anterior and posterior lobes of the pronotum sub- 

 equal in length brasiliensis Bruner 



aa. Tegmina more densely reticulate; the post-radial area densely and irregularly 

 reticulate and without an intercalary vein; the posterior lobe of the pronotum 

 longer than the anterior one. 

 b. Hind tibiae provided with 9-11 spines in outer row; size moderate, 

 c. Tegmina irregularly marked with rather small dark blotches. Hind tibiae 



pale, with the apical third bluish consperms Bruner 



cc. Tegmina regularly marked with large maculations. Largely green, or with 

 the hind tibife and the lower sulcus of hind femora red.
