and Boot Kcy^^ are probal)ly individual in the main and not geo- 

 graphic. As there stated, however, south Florida material is always 

 larger than Thomasville, Ga., specimens, although occasionally 

 but slightly so. The Big Pine Key series is quite similar in general 

 size to the individuals previously measured from Boot Key and 

 Key Vaca, although a single female is distinctly larger and subequal 

 to the smallest of the Long Key females, while one Homestead male 

 is subequal in proportions to the maximum Long Key males. Ex- 

 tremes of the present Homestead and Big Pine Key series, as well 

 as the Key West female, show the following measurements in milli- 

 meters:

The material from the keys which have scrub cover (Key Biscayne, 

 Long Key, Key Vaca, Boot Key, and Key West) is all either uniformly 

 colored or of the strongh' bicolored phase {i.e., dorsum solidly paler 

 than the lateral aspects), while that portion of the material from 

 pine woods (Miami, Homestead, Detroit, and Big Pine Key) contains 

 thirteen specimens distinctly lined with black on each side of the 

 median carina of the pronotum, in a number also distinctly punctulate 

 with dark brownish on the tegmina. The single nymph from Detroit 

 and one of the four from Homestead have the blackish lineations on 

 the pronotum, showing that this coloration is fixed before the adult 

 condition is reached. 



At Homestead the species was uncommon in the pine woods, 

 nymphs, however, being abundant, while the single nymph from 

 Detroit was in similar surroundings. In the pine woods on Big 

 Pine Key the species occurred in fair numbers, while the Key West 

 female, all seen at that locality, was taken in the scrub.
