The present form and A. brevicauda and limifera constitute a 

 well marked group of species, characterized by having very short 

 or abbreviate tegmina in the female" and crenulate margins to the 

 dorsal abdominal segments of the same sex (this character excepted 

 in brevicauda), both sexes having more ( cf ) or less ( 9 ) distinct stru- 

 mose lateral longitudinal lines on the abdomen, while the male sex 

 has the stridulating field of the tegmina broad and with its free mar- 

 gin strongly or abnormally produced at the apex of the stridulating 

 vein, while the male cerci are not abruptly recurved at the tips. 



'" Presumably so in limifera, but the female of that species is not known.
