On Phrynotettix magellanicus Bruner and Tristira 



bergi Brunner (Orthoptera). 



By JAMES A. G. REHN. 



In 1872, Glover, in his illustration of North American Ento- 

 mology (Orth., pi. vi, fig. 25), applied the generic name 

 Phrynotettix to the figure of a species of the genus later 

 called Haldiiianclla by Saussure,* who apparently had never 

 seen Glover's work. In a work published several years before 

 the one containing Haldmanella, Saussure described a peculiar 

 South American genus of locusts and applied the name 

 Phrynotettix to it.t From this it will be seen that Phrynotettix 

 must date from Glover and should be used in place of Hald- 

 inanclla, which has already been done by the author,! Phryno- 

 tcttiv Saussure falling on account of preoccupation. The latter 

 genus was described by Saussure as a member of the Oediopo- 

 dinae. 



In 1900, Bruner described a species of Phrynotettix Saus- 

 sure || from the Straits of Magellan, and two months later, 

 Brunner von Wattenwyl independently described the same 

 species as a new genus and species of Truxalinae Tristira 

 bergi.% 



Eary in 1906, the author recorded specimens as the latter 

 species, overlooking Bruner's species, as its proper relationship 

 appeared to be with the Truxalinse (Acridinae). 



A re-examination of the material sustains the opinion that 

 closer relationship exists to the Acridinse than to the CEdipo- 

 dinre, but the. proper position of this as well as several other 

 genera is debatable. From the evidence given above, it is ob- 

 vious that Tristira must be used as the generic name and that 

 magellanicus Bruner has priority over bergi Brunner, the cor- 

 rect combination being Tristira niagcllanica.
