PSYCHE. 



[April 1S91 



southern part of the state but thinks it 

 is rarely found there. I do not know of 

 its occurrence elsewhere. 



^y. Dissosteira Carolina Linn. 

 Abundant everywhere along roadsides 

 and railroads especially. Taken as early 

 as the 25th of June. 



*5S. Spharagemon aequale Say. It 

 is not certain that this species occurs 

 in the state although Thomas says it is 

 found "throughout the greater part of 

 the state." It is in no collections that I 

 have seen while the species next named 

 is abundant wherever I have collected 

 in Illinois or Iowa or Indiana ; but as its 

 occurrence here is not improbable I 

 have not excluded it from the list. 



59. Spharagemon bolli Scudd. Com- 

 mon on dry hillsides. It makes its ap- 

 pearance as early as the 21st of June. 

 This is the only species with which I 

 am acquainted, except Dissosteira car- 

 olina Linn., that remains stationary a. 

 few feet above the ground and in some 

 manner produces a dry rustling note. I 

 have known this species to go through 

 the pei'formance in but one instance 

 although it was repeated several times 

 by different individuals. As four out of 

 the five individuals that I captured on 

 the spot were males, the thought sug- 

 gested itself that it might be a part of 

 the courtship of the species. 



60. Spharagemon collare Scudd. 

 This species occurs rarely on the tops of 

 high sandy hills, in Rock Island Co. 

 and doubtless throughout the state as I 

 have found it as far south as Pine Bluff, 

 Ark., where individuals were found 

 abundant along the sandy shore of the 



Arkansas River. They are abundant 

 however on the "Sand Hill." They have 

 been taken at Moline as early as the 2Sth 

 of August. 



61. Psinidia jfenestralis Serv. This 

 has been found, so far as I know, in but 

 a single locality in the state, the sand 

 hill at Moline Bridge. It is abundant 

 here on the bare sand. Its crimson 

 wings make it conspicuous but when 

 on the ground it is so small and colored 

 so nearly like the sand that it is not easy 

 to see it and its flights are so short and 

 quick that it is not very easy to capture. 

 Aug. 28th is the earliest recorded date 

 of its capture. 



*62. Mestobregma cincta Thos. Said 

 by Thomas to occur sparingly in south- 

 ern Illinois. 



63. (?) Philobostroma parva Scudd. 

 I think I am not mistaken in referring to 

 this species a considerable number of 

 individuals found on the sand hill, Sept. 

 2, and at Cordova Sept. 28. They are 

 very variable in size and color but as the 

 lateral foveolae are always very distinct 

 they are easily distinguished from 

 Philobostroma quadrimaculata Thos. 



*6^. Trimerotropis maritima Harr. 

 Said by Thomas to occur in the north- 

 ern part of the state. 



65. Circotettix verruculattis Kirby. 

 The collection of the State laboratory 

 of natural history contains two speci- 

 mens, one from Henry, 111., and the 

 other from Birds Point, Mo. 



66. Chloealtis viridis Scudder. 

 Seems to be common throughout the 

 state, but it is never abundant. Speci- 

 mens of both the brown and srreen varie-
