at the end than in the other sub-families whose members oviposit in the 

 earth or in stems of grass. This sub-family is represented in Indiana, so 

 far as known, by three genera and eight species. 



Key to Genera of Phaneropterinje. 

 a. Wing covers of equal breadth throughout ; supra-anal 

 plate of male with a long decurved spine which is 



notched at the end I. Scudderia. 



mi. Wing covers widest in the middle ; supra-anal plate 

 of male not as above. 

 h. Hind femora but little if any shorter than wing 

 covers ; ovipositor well developed, curved grad- 

 ually upwards II. Amblycorypha. 



bb. Hind femora much shorter than wing covers; 

 ovipositor very short, turned abruptly up- 

 wards III. MlCROCENTRUJI. 



1. Scudderia, Stal (1873). 

 This genus includes Katydids of medium size, with the wing covers 

 long, narrow, of nearly equal width throughout, and rounded at the ends. 

 The vertex is deflexed, compressed, and hollowed out on either side for 

 the better accomodation of the eyes, which are nearly hemispherical. 

 The hind femora are long and slender, almost equalling the length of the 

 wing covers in some of the species. The ovipositor is short, broad, curved 

 sharply upwards, and has the apical third finely crenate on both margins. 

 The males are readily distinguished from those of other genera by having 

 both anal plates projected into long curved processes; the one from the 

 supra-anal plate curving downwards and notched or forked at the end, 

 that from the sub-anal curving upwards, and likewise notched. The 

 form of these processes, together with that of the notches serve as valu- 

 able characters in distinguishing the species. Six species have been 

 described from the United States, four of which occur in Indiana. 



«. Length of posterior femora 28 or more mm. * 

 b. Notch of supra-anal spine of male square with a slight median 

 tooth, almost as' wide as the middle, of the upturned sub-anal 

 spine ; the lateral processes slender and compressed. 



Note.— The measurements in this paper are given in millimeters, an inch being 

 equal to very nearly twenty-five millimeters. The measurements given arc, when pos- 

 sible, the average of a number of specimens, and the "length of body" does not in- 

 clude the sexual appendages of male nor the ovipositor of female.
