crenate on the inner side. Length 4.5-5 mm. (Fig. 365.) 



Throughout the State; common. February 8-November 20. 

 Our most robust species of Atwnius resembling Aphodius in general 

 appearance; readily known by the finely wrinkled 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 

 Aphodius fly by thousands and are attracted by electric lights in 

 great numbers. Also frequents fungi. 



1747 (10,183). ATiENius lecontei Harold, Col. Hefte, XII, 1874, 19. 

 Elongate-oval, moderately convex. Piceous or black, shining; legs red- 

 dish-brown, antenna? paler. Clypeus impressed in front, broadly but feebly 

 emarginate, slightly angulate each side, finely and obsoletely punctured; 

 vertex coarsely punctate. Thorax about one and a half times as wide as 

 long, sides feebly curved; apex and base equal, base curved at middle, 

 oblique each side near the hind angles, which are obtuse. Elytra oblong- 

 oval, striae deep and rather broad, with coarse, not serrate punctures ; in- 

 tervals convex, subcarinate at apex, each with a row of indistinct punc- 

 tures on the inner side. Length 3.5-4 mm. 



Crawford County; rare. June 18. A southern form, whose 

 range was given by Horn as "District of Columbia to Louisiana."

Oblong, parallel, convex. Pic- 

 eous-black, shining ; legs, sides of 

 clypeus and very narrow front mar- 

 gin of thorax reddish-brown. Cly- 

 peus moderately impressed in front 

 sides broadly rounded, their surface 

 with numerous fine wrinkles ; vertex 

 coarsely and sparsely punctured at 

 base, more finely in front. Thorax 

 one and a half times as wide as long, 

 sides feebly curved, hind angles 

 rounded, base curved with deep mar- 

 ginal line ; disk with sparse, coarse 

 punctures, with finer ones every- 

 where intermingled. Elytra as wide 

 at base as thorax, humeri dentate, 

 sides nearly parallel, stria? punc- 

 tured ; intervals very finely punctate.
