Aphodius sallaei Harold. 



Berl. Ent. Zeitsch., 1863, p. 336. 



Specimens agreeing with Von Harold's description were taken at 

 light near Brownsville, Texas. Bales in the " Biologia " records it 

 from Mexico to Costa Rica. 



This species is similar in form to ruricola, dark brown, elytra paler with some of 

 the intervals either entirely or partly dark brown or piceous ; the striae are deeply im- 

 pressed and crenately punctate ; the intervals feebly convex and finely punctate; the 

 thorax is finely punctate, with some larger punctures intermixed ; head trituberculate, 

 feebly so in the female ; gense distinct ; clypeus emarginate in front with angles 

 reflexed and rounded ; mesosternum not carinate. 



Aphodius arizonensis, new species. 



Moderately elongate, reddish brown. Head densely punctate, front feebly tuber- 

 culate ; genre prominent, rounded ; clypeus more coarsely punctate than the head, 

 frontal margin reflexed and arcuate-emarginate, angles rounded ; margins not fimbri- 

 ate. Thorax twice as wide at base as long, scarcely narrowing to the front ; sides 

 feebly arcuate, margin not explanate ; front and hind angles rounded ; base finely 

 margined ; surface finely punctate with coarser punctures intermixed, the coarser punc- 

 tures more numerous and denser at sides, on the disk a smooth median line. Elytra 

 not wider than the thorax at base ; humeri obtuse ; sides feebly arcuate ; strire moder- 

 ately deeply impressed, not very coarsely punctate ; intervals slightly convex, finely 

 punctulate. Underside finely punctulate. Mesosternum not carinate. Anterior tibiae 

 strongly tridentate externally; impunctate on the upper surface ; first tarsal joint .shorter 

 than second. Posterior femora sparsely punctulate ; apex of hind tibire with equal 

 spinules, first joint as long as the next three. Length 5 mm. 



Huachuca Mts., Arizona. 



This species resembles inilitaris somewhat, btit has to be placed in 

 Dr. Horn's group B. From all the species in this group it will be 

 readily recognized by its uniform reddish brown color. 



Bradycinetus serratus var. peninsularis Schaef . 



Trans. Am. Ent. Soc. , vol. xxxii, p. 252. 



This variety, which I described from Lower California, occurs also 

 in Arizona (Phoenix). 



Diplotaxis rugosioides, new species. 



Form ol sordida, black with feeble reneous luster. Head coarsely densely punc- 

 tate ; genre not prominent ; clypeal suture distinct at sides, obliterated at middle ; cly- 

 peus coarsely and densely punctate, margin reflexed and emarginate at apex, angles 

 broadly rounded. Thorax slightly more than twice as wide at base as long ; sides 

 arcuate slightly behind middle, obliquely narrowing to base and apex ; basal angles 

 obtuse, apical angles acute ; a depression near basal and apical angles also along the 

 base ; surface moderately coarsely and very densely punctate, clothed with very short.
