PSYCHE. 



[May 1891. 



full grown specimens as early as the 5th 

 of June. The museum of the State lab- 

 ratory of natural history contains a few 

 specimens from Normal and Blooming- 

 ton, 111. My collection contains speci- 

 mens from Bloomington, Indiana. 



SS. Pezotettix occidentalis Brunei - . 

 A very common species which makes 

 its appearance as early as the middle of 

 July and is abundant through August 

 and September. 



89. Pezotettix scudderi Uhlev . This 

 is probably as common as the last men- 

 tioned species and probably more evenly 

 distributed throughout the territory 

 which it occupies. Occidentalis cer- 

 tainly prefers grassy hillsides and tops, 

 but scudderi is very frequently found 

 along roadsides or in pastures. It 

 reaches maturity about the first of Au- 

 gust. It is tolerably certain that unicolor 

 Thos. is but a synonym of this species. 

 Mr. Uhler's specimens were from Balti- 

 more and Rock Island, and it is not 

 probable that I overlooked the species 

 during four years collecting in the 

 neighborhood of the last mentioned 

 place. Mr. Thomas distinctly states 

 that he was unacquainted with sczidderi. 

 So it is scarcely to be doubted that he 

 redescribed this species as zuticolor. 



90. Pezotettix gracilis Brunei - . This 

 is P. minzitipennis Thos. It is very 

 rare in the north-western part of the 

 state, but seems to be widely distributed, 

 as specimens have been found at Moline, 

 Bloomington, Urbana and Normal. It 

 is a wood loving species. It has been 

 taken as early as the first of July. 



91. Pezotettix autumnalis Dodge. 



The occurrence of this species was some- 

 thing of a surprise as it was thought to 

 be a local Nebraska form. Its peculiar 

 distribution here however leads me to 

 think that it may be a widely spread 

 species and explain perhaps why it has 

 been supposed to be so restricted in its 

 range. It occurs in abundance at one 

 place near Colona, Henry Co., 111., ac- 

 cording to Professor Garman, who gave 

 me specimens obtained at that point and 

 saw nothing of it anywhere else, but sev- 

 eral days search for the species was en- 

 tirely fruitless, and I was almost inclined 

 to think some mistake had been made in 

 referring the specimens to that part of 

 Illinois, when I stumbled upon the spe- 

 cies at Cordova, Rock Island Co. There 

 I found it abundant in a large orchard 

 on the east side of a high hill. Careful 

 search in that neighborhood did not en- 

 able me to find it any where else, and 

 I have never found it in any other 

 part of the state. The Colona speci- 

 mens were captured Aug. 20th, 1S85. 

 Those captured at Cordova were taken 

 the zSth of September, 1889. 



92. Pezotettix viola Thos. This is a 

 south-western form not generally dis- 

 tributed throughout the state. Said by 

 Thomas to inhabit central and southern 

 Illinois, but the museum of the State 

 laboratory of natural history contains 

 but two specimens captured at Running 

 Lake July 15, and in September. Mr. C. 

 W. Woodworth of Fayetteville, Ark., 

 has repeatedly observed females of this 

 species ovipositing in crannies of wood 

 and stone frequently three or four feet 

 from the ground.
