244 PROCEEDINGS OF THE ACADEMY OF [June, 



of immaturity for specimens of a smaller, lighter, and more uniformly 

 colored species of the genus. 



The series here recorded was taken in a great variety of situations. 

 Many were on the underside of coquina boulders, some between 

 boards piled in a field and some under the bark of a dead pine log. 



ACRIDIDiE. 

 Apotettix rugosus (Sc.). 



.Miami, Fla., March 28, 1910; 6 <? . 

 Homestead, Fla., March 17-19, 1910; 5 d 1 , 2 9 . 

 Key West, Fla., March 15, 1910; 1 &. 



Considerable variation in the shape of the tegmina exists in this 

 scries, some individuals having the form distinctly oval, others have 

 the ventro-distal margin more or less distinctly oblique-arcuate. 

 These tettigids were taken at Miami and Homestead in small moist 

 spots in the pine woods covered with very low swamp vegetation; 

 at the latter place £hey were also taken in a marshy arm of the 

 everglades. The specimen taken at Key West was beaten from 

 Ilex cassine in a "powder-dry" field. 



Neotettix variabilis Hancock. 



Miami, Fla., March 28, 1910; 1 9. 



Cocoanut Grove, Fla., 1887; 1 9 (Type) [U. S. N. M.]. 



This species is very close to N. femoratus (Sc), agreeing in general 

 form, character of dorsum of abdomen, and shape of the frontal costa; 

 differing only in the smaller size, distinctly smaller tegmina, and 

 regular dorsal carina of the caudal femora. More material may 

 show this to be a geographic race of N. femoratus. The specimen 

 from Miami was taken in a low spot in the pine woods near the 

 south bank of the Miami River. 



The type differs from the specimen from Miami in being more 

 scabrous on the dorsum of the pronotum, much like specimens of 

 N. coarclatus, but fully agreeing in the essentials, i.e., the form of the 

 facial forks and the short, apically rounded tegmina. The regularity 

 of the dorsal carina of the caudal femora is not as marked in the 

 type as in our specimen.
