 Omaloteltix Bruner, Proc. U. S. Nat. Mus.. XXX, p. 642 (1906). 



The genus Otnalotettix Bruner, according to W. F. Kirby of the 

 British Museum, is the same as Abracris of Walker, which was based 

 on A. dilecta from Santarem, Brazil. This genus was reviewed in 

 the Biologia Centrali-Americana where the annexed synoptic table of 

 the known species was published. It is modified herewith to include 

 Walker's species dilecta.
