probably occurs in Indiana, but has not, as yet, been noted. It is con- 

 siderably smaller* than laurifoliurn, and with the general color more of a 

 yellowish green. 



PSEUDOPHYLLINJE. 



This sub-family is represented in Indiana by the single genus Cyrtophyl- 

 lus the leading characters of which are given below. 



IV. Cyetophyllus, Burmeister (1838). 



The members of this genus are at once distinguished from all other 

 Locustidte by the broad leaf-like form of the tegmina which are longer 

 than the wings, obtuse and rounded at the end, and concave or hollowed 

 within. The vertex extends forward between the eyes in the form of a 

 small flat spine and the prosternum is armed with two sharp spines. Eyes 

 small, globose. The "shrilling" organ of the male is brown in color, 

 with the central portion as transparent as glass, and is set in a strong 

 half oval frame. Ovipositor broad, with the apical half up-curved and 

 denticulate below ; apex rather sharply pointed. Sub-anal plate of male 

 produced into a long paddle shaped appendage which is grooved on the 

 upper side. 



But two species occur in the Ignited States only one of which is rather 

 common in Indiana.
