tip of the hind tibiae. In Pterophylla the tegmina is 

 broadly expanded in the middle and the pronotum is 

 crossed by two distinct grooves.

do not know, by sight, either the disputant 



or Katy, both of whom usually stay high in trees. Plate 

 XIX shows the male; the musical apparatus is at the base 

 of the tegmina, and the leaf-like wing-covers themselves, 

 broadly curving entirely around the body, act as sounding 

 boards. The female's wing-covers do not have the thick 

 rasp-veins at their bases; and at the hind end of her 

 abdomen is a stout scimitar-like ovipositor with which she 

 places her eggs in the bark of various trees. In many of 

 the older books this species is called Cyrtopliyllus concavus, 

 ana has been nicknamed the True Katydid. 



The "folia" part of the scientific name 

 Amblycorypha refers to the leaf . like appearance of the 

 oblongifolia 



front wings. Nearly all of the Katydids are 



typically green, but, like some other green insects, they, 

 and especially this species, have brown or pink "sports" 

 (see Plate XIX). The figure is of a female and shows the 

 ovipositor. The "Oblong-leaf" and the other relatives of 

 the True Katydid often live in low bushes. 



Under this general head we may group 



ea ow numerous species of Neoconocephalus (rather 



Grasshoppers 



large, green or brown species, with the 



front of the head more or less prolonged into a cone, and 

 with spines on the underside of the front and middle 

 femora), Orcliclimum (usually an inch, or slightly more, 

 long; females have stout and curved or sickle-shaped 

 ovipositors), and Conoceplialus (smaller, as a rule; the 

 ovipositor is slender and straight; prosternal spine very 

 short ; see Plate XX). Some authors class Neoconocephalus 

 with Katydids rather than with Meadow Grasshoppers 

 and, as a matter of fact, these insects are rather partial to 

 bushy fields. The name Conoceplialus is apt to cause 

 some trouble to those who consult books which w r ere
