80 THE CANADIAN ENTOMOLOGIST. 



A rare species, having been noted on but one occasion, along the 

 sandy embankment of a railway, when, perhaps, a dozen specimens were 

 taken on Oct. ii. The males were very brightly coloured, having 

 evidently just moulted for the last time. Like the preceding species, it 

 flies more often than it hops, moving with the same rapid flight, but not 

 so far as 6". Americana. 



A single specimen of this species was taken in Monroe Co., Ind., in 

 1 886, and at the time was referred to A. e?fiarginatuin, Uhler, with the 

 description of which, as given by Thomas, it closely agrees. It is not 

 recorded from Illinois, nor from any locality nearer than Ivansas, as far 

 as I can ascertain.

Pezotettix rotundipeiinis, Scudd., Proceed. Bost. Soc. Nat. Hist., 

 XIX., 1877, 86. 



This species was named for me by Dr. Scudder, as I did not have 

 the description cited above at the time it was taken. It has been known 

 heretofore only from Florida. In Vigo County it is rather scarce, and 

 frequents the borders of blue grass pastures and roadsides. The female 

 appears much more common than the males, only two or three of the 

 latter having been seen. It has been taken as late as Nov. 22, when two 

 females were found on the lower plank of a fence enjoying the sunshine. 

 A single pair were noted in copulation Oct. n, 1890. 



17. Pezotettix scudderi, Uhler. Scudder's Grasshopper. 



Pezotettix scudderi, Thos., Syn. Acrid. N. A., 1873, 152. 



Id., Ninth Rep. St. Ent., 111., 1880, 121. 



In October and November this species is very common in open 

 woods and pastures, especially near the borders of them, where upon the 

 lower part of the fences it delights to collect during the short autumn 

 afternoons. 



18. Pezjtettix viRiDiPES (?) Walsh, Mss. 



A single specimen taken from the roadside on Oct. 11, 1890, was 

 referred to Dr. Scudder for identification. He returned it with the above 

 name marked doubtfully, stating that it " differed from the typical speci- 

 men in the nearly complete obliteration of the median carina of the 

 prozona." I have seen no description of it.
