The specimen before us was taken in short, heavy grasses growing 

 on the scant soil near a depression, where long-continued search failed 

 to reveal other individuals.

This species varies appreciably in size in both sexes, while the 

 extent to which the caudal portion of the wings extends caudad of 

 the tegmina varies from one-half to four-fifths of the length of the 

 caudal femora. In all of the adults in the above extensive series 

 the tympanum of the cephalic face of the cephalic tibiae is distinctly 

 indicated. 



A single male from Punta Gorda, De Soto County, Fla., taken 

 November 17, 1911, by W. T. Davis on mangrove (B. I.), is also 

 before us. It is slightly smaller than the smallest of the present 

 series, but otherwise shows no differences. 



The series taken at Miami was captured by beating heavy foliage 

 in "jungle growth"; on the Keys the species was found not uncom- 

 mon on a great variety of bushes, vines and trees, many were beaten 

 from Ilex cassine, while numbers were heard and some few taken 

 from the foliage of the mangroves. 



The sound produced by the males of this species is very delicate 

 and high-pitched — a clear, tinkling note which is very pleasing. 



Hapithus quadratus Sc. 



Miami, Fla., March 28, 1910; 1 n: November 15, 1911 (Engle- 

 hardt); 1 n. [B. L]

The adult specimens were all captured by beating low bushes, such 

 as Ilex cassine, and high plants, while the nymph taken at Miami was 

 found in the undergrowth of the pine woods. 



53 The record by the authors of C. delicalula Scudder, from Key West and 

 Miami (these Proceedings, 1905, p. 51), is an erroneous identification of the 

 present species. Since that date we have been able to examine, the typical 

 material of C. delicatula and ascertain its true relationship to the specimens in 

 hand.
