REHN AND HEBARD 53 



marsh vegetation (Gregory) or in dense clumps of coffee bean 

 {Sesban macrocarpa) growing from six to ten feet high on sandy 

 soil back from the gulf beach (Galveston). Its note was a long 

 buzzing zeeeeeee, somewhat resembling that of some cicadas, with 

 but few interspersed clicking sounds. At Gregory the song was 

 noticed to be especially loud during the morning, again increasing 

 in volume at night, but in a more subdued tone and different key. 



Morphological Notes. — -Theventro-external margin of the caudal 

 femora is usually unarmed, but in two specimens we find a single 

 spine on one or the other margin, another has two spines on one 

 margin and a third specimen has a single spine on one limb and 

 three on the other. 



The two Galveston paratypes and the Rosenberg pair have the 

 tegmina and wings shorter than the remainder of the material, 

 which have proportions about as in the type.

A careful study of Redtenbacher's description has resulted in 

 our placing pulchellum as a synonym of laticaudu. Mr. Davis
