July 9 read as follows: "This pretty little locust is just reaching maturity. I 

 secured seven specimens, five males and two females, on the prairie north of 1626 

 Holyoke." 



40. Hesperotettix speciosus Scud. 



Found in situations similar to the above, but especially along sloughs. 

 It is not a numerous species in Sedgwick county, and reaches maturity late in July. 

 Prof. Lawrence Bruner says that they feed on several species of Helianthus. 



41. Hypochlora alba Dodge. 



Found in pastures and waste fields, especially on a silver-colored sage- 

 weed, to which it is well adapted by protective coloration. It reaches maturity 

 about the middle of July, and is found until October. Several specimens were 

 taken at Wichita July 20, 1904. 



42. Campylacantha olivacea Scud. 



Found in pastures and waste fields in company with M. gracilis. 

 Reaches maturity late in July. 



43. Melanoplus atlantis Riley. 



One of the most widely distributed species found in Sedgwick county. 

 Upland prairies, waste fields, stubble, along streams, and in meadows. In no one 

 place, however, was the Lesser locust found in large numbers. First adult speci- 

 men taken May 30, 1904. Common from' June to November. 



44. Melanoplus bivittatus Say. 



The Two-lined locust is common early in July in pastures and along 

 roadsides. Several specimens taken on Fairmount July 8, 1904, 



45. Melanoplus coccineipes Scud. 



Only two specimens secured, male and female; found in waste field, 

 sandy soil, Nickerson farm, June 30, 1904. 



46. Melanoplus diflferentialis Uhler. 



Very common ; found in fields, gardens, and roadsides. Reaches ma- 

 turity by the middle of July. Taken in Brown, Sedgwick and Harvey counties. 



47. Melanoplus femur-rubrum DeGeer. 



The common red-legged locust is found everywhere that vegetation 

 grows, from the middle of August to November. Alfalfa-fields, however, are fa- 

 vorite places. A small alfalfa field on Fairmount was mown the afternoon of 

 September 14, 1904. By sweeping in the tall grass growing along the north side 

 of the field I secured 161 adult Acridida?. Of these, 121 were femur-rubrum; 

 fifty-one males, seventy females. My notion would be that this species would 

 average one-half bushel or more to the acre in the alfalfa-fields of Sedgwick 

 county any time during September. 



48. Melanoplus gracilis Brun. 



Found along sloughs, in waste fields, and in gardens. Reaches ma- 

 turity late in July. Not reported from Kansas. 



49. Melanoplus impiger Scudd. 



Only three specimens of this species in my collection. Taken in a 

 prairie pasture on the Nickerson farm, August 31, 1904. 



50. Melanoplus luridus Dodge. 



This species is rather common on the open prairies in September. It 

 did not come under my observation until September 7, 1904, when several speci- 

 mens were taken on Fairmount. Afterward it was found to be fairly numerous. 



51. Melanoplus minor Scudd. 



Found in pastures and meadows; common during June, but not nu- 

 merous. First adult taken June 4, 1904. Not reported from Kansas.
