Homestead, but locally common at Miami. The saltatorial ability 

 of this insect is surprising, but it is easily taken owing to the fact that 

 its movements are seldom hasty.

 were exceedingly abundant). 



We have examined the entire series previously recorded from 

 southern Florida by us as well as the material now being studied 

 and find that, when compared with specimens of the type series from 

 Georgia, 32 the individuals from Miami, Cape Florida on Key Biscayne 

 and Homestead are considerably smaller, more attenuate, with 

 proportionately longer tegmina and wings and usually lighter colora- 

 tion. There are no characters to be found in the series, however, 

 which would warrant its being considered a racial form. The 

 specimens before us from Thomasville, Ga., agree in every re- 

 spect with typical specimens.

31 These specimens show conclusively that the species first reaches maturity 

 at Miami in late March. All of these specimens have recently reached the adult 

 condition, and seven have the curved white fine peculiar to the nymphal state 

 still indicated on the sides of the pronotum. 



32 These specimens were sent to Professor Bruner by Mr. Scudder and are now 

 in the Hebard Collection ex Bruner.

34 These specimens in nymphal stages have the bands of the caudal femora 

 already well marked.
