THE CANADIAN ENTOMOLOGIST. 169 



Aphodius, Illiger. 

 A. Kansamis, n. sp. — Moderately robust, broader beliind, convex. 

 Colour, pale yellowish testaceous, shining, head more reddish, prolhorax 

 with irregular dark discal cloud, elytra maculate. Head without tubercles, 

 alutaceous, finely and sparsely punctate, clypeus with broad, shallow 

 emargination, edge shghtly reflexed, without denticles, angles rounded, 

 gense moderately prominent, and bearing a few long bristles. Antennae 

 pale yellow. Prothorax broad, widest in front of the middle, sides fimbri- 

 ate, arcuate, narrowing to the base, which is not regularly rounded, but 

 more produced at middle, marginal line distinct, rather deep in some of 

 the specimens ; disk convex, finely alutaceous, the punctures somewhat 

 larger than those of the head, sparsely placed, almost wanting near the 

 hind angles. Elytra at base about equal to the prothorax, broader pos- 

 teriorly, finely alutaceous, stride rather fine and shallow, impunctate, inter- 

 vals nearly flat, with a row of extremely fine serial punctured. Body 

 beneath, smooth and shining, a few setigerous punctures on the thoracic 

 segments and a row on the anterior edge of each segment of the abdomen, 

 the last ventral with scattered setje over the entire surface. Mesosternum 

 opaque, not carinate. Legs moderately slender, anterior tibiae smooth on 

 their outer faces, tridentate, apical tooth normal, long and pointed, the 

 second large, the upper one small, margin above this tooth not crenulate. 

 Hind femora with a few setigerous punctures, tibije fimbriate at apex, with 

 rather large, unequal spinules, the transverse ridges practically obliterated, 

 first joint of hind tarsi a trifle shorter than the next three. Length, 3 mm., 

 Lj2 inch. 



' '■ " This insect belongs to that group of Aphodius in which the scutellum 

 is short, and may be placed in Dr. Horn's group Ic, where it will follow 

 A. iarrece, from which it differs in size, colour, the strong marginal line of 

 the prothorax, and presumably in the secondary sexual characters which 

 are well marked in larrece, though my series of several Kansanus show 

 no definable differences in those parts usually affected. The maculaiion 

 of the elytra in Kansanus is of a simple type, consisting of an indefinite, 

 broken arcuate band composed of several detached bngitudinal brownish 

 spots, reaching from humerus to humerus and crossing the suture in front 

 of the middle ; the suture and a small subapical spot also brownish. 



For a good series of this interesting beetle, I am indebted to Mr. 

 Warren Knaus, who took it in some numbers at Englewood in south- 

 western Kansas.
