A very handsome and striking Floridian species. Taken in 

 August and September in some numbers by R. & H. between De- 

 Fuuiak Springs and River Junction ; also at Grand Ridge and 

 near Kissimrnee. It occurs only iu low swales between the sand 

 ridges. Scudder's types were taken near Jacksonville, and he 

 considered it as only a color variety of laticauda, it having been 

 raised to specific rank by R. & H. (1914a, 289).

 len, and normally embrace the sides of the upcurved subgenital plate near 

 the end of the latter. Ovipositor rather short, the dorsal margin sud-

This fork-tailed katydid occurs in all portions of Indiana, hav-

 In the hillv regions of the southern counties it is verv common

and practically the only species of Kcndderia noted, texensis and 

 curricfimla occurring about the marshes of the more level coun-

 of f n rca t a appear about July 1~>, but they do not become plentiful

 as late as September 18. It is most frequently seen on the low
