Anterior tibiae above the lateral tooth simple, alternate inter-

[Trox scutellaris Say. 



1824. Trox scutellaris Say, Journ. Acad. Nat. Sci. Phila., iii, pp, 

 238-239. Le Conte ed., ii, p. 140. 



No specimens of scutellaris are at hand from Nebraska, 

 but it is probable that a little careful collecting in the south- 

 western part of the state would reveal its presence. Since it 

 is a wingless species it is not likely to be found except at car- 

 rion. The recorded distribution of the species is from 

 Kansas to Mexico.] 



Trox scabrosus Beauvois. 



1805. Trox scabrosus Beauvois, Insectes recueillis en Afrique et en 



Amerique, p. 175, pi. 4b. fig. 4. 



Specimens examined: 10, from Holt Co., Cherry Co., and 

 the Sand Hills. This is the largest species of Trox, except 

 scutellaris, to be expected in the Nebraska fauna. It measures 

 15-18 mm. in length. 



Trox asper Le Conte. 



1854. Trox asper Le Conte, Proc. Acad. Nat. Sci. Phila., p. 215. 



Specimens examined: 3, two of which are labelled "Ne- 

 braska," and the other one "Lincoln, June, At light." 



Trox suberosus Fabricius. 



1798. T7-0X suberosus Fabricius, Systema Entomologiae, p. 31. 



Specimens examined: 82, from Nebraska City, Omaha, 

 South Bend, Lincoln, West Point, Fairmont, Minden, Pine 

 Ridge, and Big Spring, collected from May to August. This 

 is apparently our commonest large Trox. It occurs regularly 

 at Lincoln about the electric lights, where 70 of the above 

 listed specimens were taken.
