Genus Tetrix
Explanation of Names
Tetrix Latreille 1802
"Although Latreille first applied the term Tetrix,... it is essentially the same genus as that defined by Charpentier as Tettix. ... The word Tetrix is of Greek origin, meaning grasshopper. Harris (1841) supposed that Latreille applied the term to the Tettigida from some fanciful resemblance to the heath-cock of Europe. In North America the name grouse-locusts has to some extent been applied to Tettigids in consequence of this supposed similarity."(1)
