Bucephalacris Giglio-Tos, Boll. Mus. Zool. Anat. Comp. Torino, IX, No. 184, p. 30 

 (1894); Bruner, Proc. U. S. Nat. Mus., XXX, pp. 641, 664 (1906); Ib., Ann. 

 Carnegie Mus., VIII, p. 91 (1911). 



The species of this genus, as stated in a former paper appearing in 

 the Annals, are confined to a limited area in northern Argentina, 

 Paraguay, southern Brazil, and eastern Bolivia. They are medium- 

 sized insects of rather dull color and evidently live among the under- 

 growth in and about the margins of tropical forests. A synoptic key 

 for the separation of the known species is given on page 91 of volume 

 VI 1 1 of the Annals.

 referred here. They occur in tropical America, where representatives
