A gradual diminution of the pronotal crest is noticeable in the 

 distribution from north to south of the present race, the other charac- 

 ters which distinguish this race becoming in like manner more 

 pronounced. The material from southern Georgia may be con- 

 sidered typical. The series of twenty-three specimens from San 

 Pablo, Pablo Beach and Gainesville, Florida, which we have recorded 

 as N. cristatus,- belong to the present race. 



This race is peculiar to the Sabalian and a portion of the Lower 

 Austral zones of the southeastern United States. It is widely 

 distributed and sometimes abundant in the undergrowth of the 

 long-leaf pine woods, particularly where the ground is low, sandy 

 and water-soaked (Yemassee, Homerville, Hebardville). It has 

 also been found abundant in low spots covered with short green 

 grasses in the midst of saw-palmetto flats (Brunswick). Our material 

 indicates that this race appears adult in the largest numbers later 

 in the season than do the more northern races of the species. 



We find Morse's N. cristatus denticulatus, 21 to be merely the western 

 development of the present race showing a decided tendency toward 

 N. c. compressus. The insects, however, though not typical, are 

 decidedly nearer the present race and we have consequently placed 

 Morse's name in the synonymy here. 



Nomotettix cristatus floridanus Hancock. 



Twelve specimens at hand, recorded by the authors 22 from Lake- 

 land, Fort Myers and La Belle, Florida, show the extreme develop-

21 Morse questions the racial validity of this phase in his original description.
