I II". >S'. B.} ; Tiftou, Ga., June 6 (type of A 7 , a mm his). A compar- 

 ison of the types of both A", floridumis and N. arcuatus shows lit- 

 tle appreciable difference, except in the less rugose surface of the 

 pi-onotum and slightly more curved median carina of the latter. 

 R. & H. (1916, 133) state that floridumix "was founded merely 

 on an intensification of the charaders which constitute the race 

 iircuahts," and that florid anus is ''known only from southern and 

 central Florida, in the northern part of its range, gradually inter- 

 grading Avith arcuatus." Since floridanus has page priority I 

 have dropped the name arcuatus, the form to which it has been 

 referred being only a connecting link or intermediate form be- 

 tween the southern race floridanus and typical cristatus, and, 

 ([noting K. & H. (1916, 151), "the uselessness of a name for inter- 

 mediates between weakly defined geographic races does not re- 

 quire comment." Were no intermediate forms known, the ex- 

 amples from central and southern Florida are sufficiently dis- 

 tinctive in their larger eyes and strongly rugose pronotum to have 

 specific rank. 



A single male of .A~. c. floridanus with caudate or long prono- 

 tum was taken near Lakeland, Feb. 16, 1919, and is the first long 

 form of this race to be recorded. In color it is pitchy black with 

 a small white spot on each shoulder. The tip of the pronotum ex- 

 tends 2 mm. beyond the hind femora and is surpassed .8 mm. by 

 the folded inner wings. As in N, c. comprcssus the long prono- 

 tum with apparently lower, less curved crest gives it a very dif- 

 ferent facies from the short form. 



In addition to the localities given the race fluridannx has been 

 recorded by R. & H. under that name from Lakeland, Ft. Myers, 

 and LaBelle, Fla. (1914d), and as arcuatus from .Jacksonville, 

 Baldwin, Atlantic Beach and Live Oak (1916, 132). They record 

 the race arcuatus Hancock also from Xorth and South Carolina, 

 Georgia and Mississippi, while under the name Xomotettix cris- 

 tatu* drnticultilux it was described and recorded by Morse (1906, 

 119) from Oklahoma and Texas. Scudder (ISTTa, 90) recorded 

 Batracliidc<i crixfala from Ft. Reed, Fla., his specimens probably 

 representing the race floridanus. 



About Dunedin A~. <-. floriduniis occurs in numbers from No- 

 vember to April, perhaps throughout the year, in the low grasses 

 and other vegetation along the sandy margins of ponds or small 

 lakes, its habitats being much more hygrophilous than those of the 

 northern forms cristatus and comprcssus. It seems also to vary 

 more in color than does oniiiirrxsits in Indiana, a number of the
