While most likely to be confused 

 with its congener if any, this locust 

 should be readily distinguished even by 

 the tyro by the characters indicated in 

 the Kev, which are not merely specific 



in value but pertain to different series 

 in the genus. While the two species 

 overlap slightly in season sulphurea 

 has mostly disappeared at the time 

 xanthoptera begins to be common. 



This species varies much in color, 

 some specimens being almost black, 

 others bright reddish or yellowish 

 brown. The wings of younger exam- 

 ples are noticeably paler in color but 

 the general tint of a large series is quite 

 uniform. Sometimes the veins, and 

 rarely the venules of the whole disk, 

 are somewhat suffused with brownish. 

 In about one-fifth of the specimens 

 examined the subfrontal shoot extends 

 one-half of the distance to the base of 

 the wing. I have yet to see an orange 

 winged example from New England, 

 but in a series collected for me at Clay 

 City, 111., by S. W. Denton, about one- 

 half of the specimens have the disk of 

 the wing of a deep reddish orange. It 

 is possible that this is a distinct race or 

 even species but the structural differ- 

 ences are extremely slight. 



Xanthoptera is equally common with 

 its congener of the spring-time and is 

 found in the same situations, viz., amid
