is more decidedly defined in the paler color than in the other speci- 

 mens. In every other respect, however, these specimens are typical. 



Distribution. — The present species is known from the vicinity of 

 the District of Columbia, west-central Indiana, northeastern 

 Nebraska, and northeastern and south-central Kansas. 



Biological Notes. — No macropterous specimens of this insect are 

 known. 



Synonymy. — The history of the present species is a succession of 

 unfortunate occurrences. In 1885, Bruner recorded specimens of 

 Nemobius sp. from Topeka, Kan., which belong to this species; 

 later, in 1893, he drew up a description of the species which was never 

 published, hence his Cyrtoxyphus ? variegatus Bruner (Mss.), an 

 unidentifiable ijame from the literature, but the material before us 

 from the Bruner Collection shows it to be this species. 



Before 1897, Blatchley sent a series of Indiana specimens of 

 Nemobius to Scudder for determination, and the present species was 

 inexcusably identified for him as N. carolinus Scudder, hence his 

 subsequent misconception of that species, and Caudell upon seeing 

 specimens of Blatchley's material so labelled followed him in this 

 error; thus material sent him for determination by Isely was likewise 

 recorded as carolinus. 



Specimens Examined. — 19: 10 males, 9 females.
