In shape and general color the abdomen of the hybrid at a 

 glance more resembles sordidus, but closer study indicates a 

 greater resemblance to graslinellus . In the color of the last 

 segments, however, especially 7, 8 and 9, the extensive and 

 indefinite obscuring of the pale area in sordidus conceals a re- 

 semblance of this species with the hybrid which can only be 

 appreciated by a study of the specimens.

Description of a New Genus of Gryllidae with a Note 



on the Genus Aphonogryllus. 



By James A. G. Rehn.

 type apparently closest allied to Anaxipha, but the characters 

 of the male tambourine are very different from those found in 

 the latter genus. 



FALCICULA n. gen. 



Allied to Anaxipha Saussure (Miss. Scientif. Mexiq., p. 

 370) , but differing in the structure of the musical apparatus of 

 the male. This is considerably reduced in size, compressed, 

 and with an entirely different disposition of the veins. The 

 ovipositor of the female also differs in being unarmed. 



Falcicula hebardi n. sp. 



Types : ^ 9 ; Thomasville, Thomas County, Georgia. April 

 17 and 25, 1903. Collected by Mr. Morgan Hebard. [Acad. 

 Nat. Sciences, Phila.].
