 This dark variety of the green-striped grasshopper is quite frequent in 

 April and May, but rare after June i, when viridifasciata seems to take 

 its place. It is probably a mere seasonal form of that species.

Eiicoptolophus sordidus, Scudd., Proceed. Bost Soc. Nat. Hist., 

 XVII., 1875, 479- 



Locusta nebulosa, Harris, Ins. Inj., 1862, 181. 

 Rather common in upland meadows and pastures as late as Nov. 22, 

 but is never found about wet places. The males, although small in size, 

 stridulate just as they arise trom the ground with a loud crackling noise 

 similar to that made by burning stubble. It flies but a short distance 

 before alighting. 



8. Arphia sulphureus. Fab. The Yellow-winged Grasshopper. 



Locusta sulp/mrea, Harris, Ins. Inj., 1862, 177, pi. I., fig. 6. 

 Tomonotus sulp/mreus, Thomas, Syn. Acrid., N. A., 1873, 105. 



Id., Ninth Rep. St Ent, 111., 1880, 107. 

 Although very common in some parts of Indiana, this is a scarce 

 grasshopper in Vigo Co., where the next species seems to take its place. 

 It frequents dry open woods and roadsides. 



9. Arphia xanthoptera, Burm. 



Tofuofiotus xa9ithoptertis, Thos., Syn. Acrid., 1873, 105. 

 Tomojiotus sulphureus xanthopterus. Id., Ninth Rep. St. Ent 111., 

 1880, 108. 

 A common species in dry, sandy fields, prairies and borders of 

 meadows. When flushed it flies for a long distance in a zigzag way, the 

 male making a loud rattling noise with every onward motion. Dr. 

 Thomas in his later writings classed xanthoptera as a variety of 

 sulphureus, but I have carefully compared a large number of specimen.s 

 of each, and can find no intermediate forms.
