Tettigidea parvula, Morse, Biol. Cent. Am. Orth., ii, 15, 

 17, fig. (1901). Two males and two females. 



Morse says of this species: "This is the smallest and most 

 slender species of Tettigidea known to me. It resembles T. 

 plagiata in the general form of the body, but the hind femora 

 are projjortionall)- stouter, the facial costa is more prominent, 

 the crown less elevated, the vertex narrower, and the size 

 much smaller. It maj' possibl}' prove to be referable to T.
