X. Aphodius Iliiger. 1798. (Gr., "excrement + Avay.") 



The species of this genus bear a close resemblance to those of 

 Atcenivs, l)ut are nsnally broader, stouter and variegated with black 

 and dull red or yellow. They are separated from Ativnius by hav- 

 ing the outer apical angle of the hind til)in? obtuse. In mounting 

 specimens of the entire tribe of Aphodiini care should be taken to 

 stretch out the hind legs so that they may be easily examined. The 

 known species of North American Aphodius number more than 80, 

 and are among our most numerous scavengers. They occur in great 

 abundance in the dung of horses and cows, into which they burrow 

 almost as soon as dropped from the animals. None of them con- 

 struct balls for transportation, and the lai'vu' go through their 

 chang(^s on the si)ot. On the first warm days of (virly spring they 

 are on the witig by myriads along (}\(\yy roadside and in and about 

 barnyaids, and tlidisands meet their death about llie ch'ctric liglits 

 of cities. Seventeen sjxicies have Ix'cn taken in Ihe State and tlircc 

 others perhaps occur.
