LOCUSTIDAE — PSEUDOPHYLLINAE 53 



Genera of Scudderiae. 

 a ^ Fore and middle femora unarmed beneath ; the hind femora 

 unarmed beneath or with few spines. . Scudderia Stal. 



a ^. All the femora spinulose beneath, Symnietropleura Brunner. 

 Scudderia has numerous species widely spread over the country 

 mostly east of the Rocky Mountains. Symmetropleura is known 

 only by a single species from Carolina, 



Amblycoryphae. 



Amblycorypha Stal is our only genus of this group, with half a 

 dozen species found in the eastern half of the continent. 



Microcentra. 



This group is represented by a single genus, Microcentrum 

 Scudder, rich in species, most of which are tropical. Its range in 

 the United States is similar to that of Amblycorypha. 



PSEUDOPHYLLINAE. 



This subfamily is barely represented in the United States, as it 

 contains but a single indigenous genus, shared with tropical 

 America. 



Genera of Pseudophyllinae. 

 a 1. Body and tegmina testaceous, the latter of only moderate 

 breadth, its anterior ulnar vein terminating not very far before 

 the apex of the tegmina, the veinlets of the costal field distinctly 

 oblique ; middle coxae with no basal tubercle. Bliastes Stal. 



a ^. Body and tegmina green, the latter of exceptional breadth, 

 its anterior ulnar vein terminating very far before the apex of the 

 tegmina, the veinlets of the costal field transverse ; middle coxae 

 with a basal tubercle. . . Cyrtophyllus Burmeister. 



Bliastes is not indigenous and has occurred only in the orchid 

 house of the Missom-i Botanic Garden, where a single specimen 

 did much damage. Cyrtophyllus is the " Katydid " and is widely 

 spread over the United States east of the Rocky Mts,, though 

 living at the north only in colonies.
