Two specimens taken there on February 6, 1904, were also studied. 

 The hoary suffusion so noticeable in the species of this genus is limited 

 in some individuals, and more general in others, very much as in the 

 closely related S. marmorata. 



In a few places in the pine woods this species was plentiful, but speci- 

 mens were hard to capture on account of their extreme shyness. (H.) 



Psinidia fenestralis (Serville). 



This sand-loving species is represented by a series of sixteen speci- 

 mens, taken at Chokoloskee, and Miami on February 6. 1904, and July 

 20, 1903. As a rule they are darker than northern specimens, and have 

 the transverse bars on the lateral aspects of the caudal femora more 

 pronounced. 



Dictyophorus guttatus (Stoll). 



This striking species is represented by four specimens taken at Miami 

 on July 11, 1903, and June 2, 1899, the latter collected by Dr. H. A. 

 Pilsbry, and in the collection of the Academy. A number of specimens 

 have also been examined from Chokoloskee, Tarpon Springs, Hillsboro 

 county (November, 1903), and Good all, Volusia county (August). 



Pseudopomala brachyptera (Scudder). 



A single adult female of this species from Chokoloskee has been 

 examined. This is the first record of this species from the Southern 

 States, 



Stenacris chlorizans Walker. 



This water-loving species is represented by a single individual from 

 Miami, taken January 30, 1903. A specimen from St. Augustine, in 

 the collection of the Academy, has also been examined. 

 Leptysma marginicollis (Serville). 



This elusive species is no doubt of regular occurrence in suitable 

 localities, ten specimens having been examined from Chokoloskee, 

 Tampa (January 17, 1904), Miami (January 16, 23, and February 2, 

 1899; S. N. Rhoads), and De Funiak Springs, Walton county (Febru- 

 ary 20; C. W. Johnson). All the specimens have the lateral lines 

 distinct. 



Specimens from Tampa were taken in the marshy places along the 

 bay. (H.) 

 ScMstocerca americana (Drury). 



This powerful species is represented by a series of thirteen Key West 

 specimens taken on January 18 and 19, 1904, two females from Cape 

 Florida, February 8, 1904, a single Chokoloskee individual and_a'series
