14. Mermiria bivittata Serv. 



This icteresting angle-head frequents prairie pastures and meadows. 

 It reaches maturity in Sedgwick county about the middle of July and is found 

 until October. The first specimens, males, were taken in tall grass along the 

 Frisco railroad east of Fairmount. In Brown county only one immature female 

 was taken, August 20, 190i. Stridulation while at rest is one of the character- 

 istics of the males. 



15. Opeia obscura Thos. 



This species was found only in short grass on the hilltops, especially 

 buffalo-grass. Only a few specimens were taken and all were females; these on 

 different dates in September. 



16. Eritetitix carinatus McNeill. 



This species is also found in pastures. Several specimens were taken 

 on the Nickerson farm May 7, 1904 ; others in the Maple Grove cemetery June 14. 

 Later in the season no specimens could be found. October 30 and November 6 

 I found two Jarvte in the third molt. When we couple this record with its early 

 appearance in the spring, it shows that this species hibernates in the nymph 

 stage. Prof. W. S. Blatchley says of the subfamily Tryxalina.-; "The winter of 

 all is passed in the egg stage." Here certainly is an exception. The male of 

 this species, like M. bivittata, has the interesting method of stridulating when at 

 rest. On Decoration day, in the Maple Grove cemetery, I observed several males 

 intent on sound-making. New to Kansas. 



17. Eritetitix tricarinatus Thos. 



Only one specimen, a female, in a pasture east of Fairmount, in short 

 grass, July 21, 1904. New to Kansas. 



18. Syrbula admirabilis Uhl. 



This handsome locust is found only on the upland prairies in tall and 

 short grass. It is rather common and reaches maturity late in August. 



19. Dichromorpha viridis Scudd. 



Unlike the other TrixalintB noted, this species is not especially fond of 

 the prairies. It is often found in brushes, and in shrubbery around houses; also 

 in timber margins and shaded places. It reaches maturity early in July and is 

 found until October. The first adult in my collection was taken July 8, 1904. 

 In Atchison county, on August 1, I found this species as one of the most com- 

 mon Acrididaj among the hills east of the city. I have taken specimens in Sedg- 

 wick, Brown, Atchison and Harvey counties. The green form is more common 

 than the brown. One specimen, a female, of the long-winged variety, punctu_ 

 lata, was taken at Sedgwick, on the Finn farm, September 17, 1904. Mr. Caudell, 

 writing from the National Museum, says : " We have no specimens of this variety 

 in the collection." New to Kansas. 



20. Orphulella speciosa Scudd. 



Exceedingly common in short grass, especially buffalo-grass. Found 

 equally abundant on high and low ground. Reaches maturity by the middle of 

 July in Sedgwick county. First adult taken July 14, 1904. This species was 

 found in all the counties where collecting was done, but is far more common in 

 Sedgwick than in the northeast part of the state. 



21. Boopedon nubilum Say. 



Only one male specimen, taken July 13, among weeds in a pasture, on 

 Fairmount.
