17. Aphodius crier atus, n. sp. 



Elongate, convex, shining black. Head coarsely punctured behind ; 

 epistoma rugose, and slightly granulate at the sides, not tuberculate, 

 deflexed towards the anterior margin, which is truncate and not emar- 

 ginate ; angles very much rounded, sides oblique, finely margined, gense 

 prominent, rounded at tip. Prothorax more than twice as wide as long, 

 narrowed behind, sides and angles rounded, distinctly margined ; base 

 not sinuate, as strongly margined as the sides ; surface with large 

 punctures, sparsely and irregularly placed. Elytra rounded on the 

 sides near the base, which is truncate ; humeri not prominent, but not 

 rounded ; strife very coarsely punctured, or, rather, cribrate ; inter- 

 spaces slightly convex, smooth. Mesosternum densely punctured. 

 Spinules of hind tibise equal. Length 5.3"'" (0.22 inch). 



Oregon, two sp'ecimens. Allied to A. cadaverinus and nevadensis, but 

 differs by the very coarsely punctured elytral striae. 



18. Aphodius anthracinus, n. sp. 



Elongate, convex, shining black. Head not densely but strongly 

 punctured, armed with three small tubercles, of which the middle one 

 in the ^ is more elevated and subacute ; epistoma obtusely emargi- 

 nate, angles broadly rounded, not prominent ; gense rounded. Protho- 

 rax nearly twice as wide as its length, narrower in front, sides rounded 

 as far as the middle, then nearly parallel to the hind angles, which are 

 slightly rounded, base scarcely subsinuate ; sides and base finely mar- 

 gined ; disc not densely punctured, punctures of two sizes, about equally 

 intermixed ; there is a narrow, indistinct, smooth, dorsal stripe. Ely- 

 tra with deep-punctured striae, interspaces slightlj^ convex, with very 

 fine punctures, arranged almost in rows adjacent to the stride. Meso- 

 sternum opake, very finely alutaceous, not carinate. Spinules of hind 

 tibiae unequal. Length 7""" (0.28 inch). 



American Fork Cafion, Utah, (9,500 feet); one specimen. Another 

 specimen from Utah was kindly given me by Dr. Horn* Belongs near 

 A. (eopardus Horn. The elytra are obsoletely spotted in one specimen. 



19. Aphodius brevicollis, n. sp. 



Elongate cylindrical, black, shining. Head not tuberculate, finely 

 punctulate, epistoma broadly emarginate in front, angles very obtuse 

 and rounded, sides oblique, flattened, rugulose, margin reflexed ; gense 

 prominent, rounded at tip. Prothorax about twice as wide as long, 

 sides nearly straight, margin strongly reflexed, front and hind angles 

 narrowly rounded; base bisinuate, not margined; disc smooth, with 

 scattered large punctures near the sides, which are broadly explanate. 

 Elytra narrower than the base of the prothorax, striae finely punctured, 

 interspaces nearly flat, smooth. Metasternum flat, alutaceous, opake, 

 not carinate, punctured only on the sides far in front. Legs dull red- 

 brown, spinules of hind tibiae unequal. Length 8™™ (0.30 inch).
