Throughout the State; eomiiiou. February S-November 20. 

 Our most robust species of Ataiiins resembling Aphodius in general 

 appearance; readily known by the finely Avrinkled clypeus and 

 coarse and fine punctures of thorax. They hibernate in large num- 

 bers in dry cow dung and beneath it, and on warm sunny days in 

 winter are on the wing. In early spring they and some species of 

 Aphodivs fly by thousands and are attracted by electric lights in 

 great numbers. Also frequents fungi.
