BIOLOGICAL PAPERS. 243 



It is very common among bunch-grase and on hillsides. On September 24, 1904, 

 along a grassy upland road in Harvey county, hundreds of this species flew be- 

 fore the team as we drove along the road. 



30. Hippiscus tuberculatus Palde Beauv. 



One specimen of this fine- looking locust was taken April 24, 1904, on 

 Fairmount hill. Mr. Caudell has not seen this specimen, but I feel sure that the 

 identification is correct. 



31. Dissosteria Carolina Linn. 



This roadside grasshopper reaches maturity in Sedgwick county about 

 July 1. After this date it is common along roads, paths, railroad tracks and bare 

 places. Of all Acrididaj, it is one of the most difficult to secure. Taken in Sedg- 

 wick, Brown and Atchison counties. 



32. Spharagemon cristatum Scudd. 



This species was not found around Wichita. In sandy fields and pas- 

 tures on the Nickerson farm it was numerous in June and July. It is certainly 

 well adapted in color to the sandy soil it frequents. June 30, 1904, was the date 

 that the first adult was taken. This species is new to Kansas. 



33. Mestobregma plattei Thos. 



The gray, ashy, gypsous soil of the bare hillsides east of Fairmount is 

 especially suited to protect this species. In suitable situations, they are to be 

 found in small numbers from the middle of July until cold weather. 



34. Mestobregma kiowa Thos. 



This species is found in company with plattei, which it resembles. It 

 is however much more numerous. I have taken specimens in Harvey, Brown and 

 Sedgwick counties. 



35. Trimerotropis citrina Scudd, 



Only on the white drift sand along the Arkansas and the Ninnescah 

 rivers have I been able to find this species. Adult specimens were not secured 

 until September. Others were taken as late as November 20, 1904. This species 

 is exceedingly wary and hard to catch. I have started them as many as twenty 

 times befere being able to get near enough to net them. New to Kansas. 



36. Hadrotettix trifasciatus Say. 



This species, as taken in Sedgwick county, is perhaps the best adapted 

 to its surroundings of any Acrididaj observed. In my field-notes of July 16, I 

 observe: "This handsome large locust was found only on the bare ground on the 

 west side of a ridge where the light colored, ashy gypsous soil is exposed. They 

 seem to feel that they are entirely secure and could be caught with the greatest 

 ease when once seen. The adaptation to soil color is striking." 



37. Schistocerca americana Drury. 



This well-known species is found in fields and pastures. Very often a 

 single specimen will be flushed, rise ten to fifteen feet high and fly rapidly ten to 

 twenty rode, lighting, if possible, on some tall weeds, bushes, or trees. I have 

 seen adult specimens from April to November. Blatchley suggests that the 

 early spring species are migratory, flying in from the south. 



38. Schistocerca alutacea Harr. 



This species is found in tall prairie-grass, especially in low places. It 

 reaches maturity about the middle of August. Found in Brown and Sedgwick 

 counties. 



39. Hesperotettix pratensis Scud. 



This is not a numerous species in Sedgwick county. I took several 

 specimens in the rank-growing prairie-grass on Fairmount. My field-notes for
