Phyllophaga gracilis Burmeister. 



1855. Trichestes gracilis Burmeister, Handbuch der Entomologie, 

 iv, pt. 2, p. 361. 



Specimens examined : 1 9 , from Hogan's Bridge, 

 Brown Co., August 3, 1902, collected by W. D. Pierce. 



[Phyllophaga glabricula Le Conte. 



1856. Lachnosterna glahricida Le Conte, Journ. Acad. Nat. Sci. 

 Phila., (2), iii, p. 260. 



No specimens of glabricula are at hand from Nebraska, 

 but the species is not uncommon at Manhattan, Kansas. 

 The species flies later in the season than most of the others, 

 from the middle of June to the middle of August, and has 

 probably on that account been overlooked in collecting. 

 It doubtless occurs along the couthern border of the state.] 



Phyllophaga futilis Le Conte. 



1850. Lachnosterna futilis Le Conte, Agassiz Lake Superior, iv, p. 

 226. 



Specimens exarnined : 400 s , 298 9 , from Dakota 

 City, Hooper, Ashland, West Point, Lincoln, Fairmont, 

 Bradshaw, Osceola and Wood River, collected from May 10 

 to July 9. About half of the specimens were taken at 

 lights, and 361 were taken on food plants as follows: elm, 

 276, dogwood 65, boxelder 5, prickly ash 4, rose 3, goose- 

 berry 2, oak 2, willow 2, blackberry 1, and poplar 1. From 

 this data it is readily apparent that futilis has a decided 

 preference for elm. It is in fact our commonest species on 

 that tree. 



Phyllophaga congrua Le Conte. 



1856. Lachnosterna congrua Le Conte, Journ. Acad. Nat. Sci. Phila., 

 (2), iii, p. 243.
