MR. HALDEMAN'S DESCRIPTIONS OF COLEOPTERA. 103 



APHODIUS ///. Mills. Coleop. de France, 178. 



A. FiMETARius Lin. (Scarab.) A. nodifrons Randall. Boston J. Nat. Hist. ii. 20. 

 Shining black ; elytra and a spot upon the lateral margin of the prothorax, red ; 

 femora black or red. 3 1. long. A common European species which is spread from 

 Sweden to the plains of the Mediterranean, and to the summit of the Alps. Rare in 

 the Eastern States. 



A. piNGUis Hald. Shining black, beneath and feet piceous, clypeus smooth, 

 pronotum coarsely punctured laterally at base ; disk minutely punctured, base 

 slightly reflexed. 3 1. long. Lake Superior. Head transverse, sub-auriculate, 

 truncate anteriorly, margin reflexed : pronotum large and convex, anterior margin 

 piceous; sides reflexed, and continued along the posterior margin: scutel concave, 

 with a few punctures; mesonotum coarsely and densely punctured: striae of the 

 elytra crenate-punctate. The form is more compact than in fimetarius, which it 

 resembles, except in colour. The description of A. concavus Say, requires a smooth 

 disk, which in pinguis has minute punctures, and is moreover smaller than his 

 ohlongus, with which he compares concavus. It is not likely that he would have 

 overlooked the punctures on the head of A. pinguis. 



A. CONCAVUS Say. J. Acad. iii. 314. Head subhexagonal, with a transversed 

 waved impressed line posteriorly; pronotum coarsely punctured laterally; disk 

 smooth, sides alone reflexed. Inhabits near the Rocky Mountains, (Say,) and at 

 Lake Superior. 



A. LjEvigatus Hald. Shining uniform rufous, an indistinct medial black spot near 

 the lateral margin of the pronotum ; hair fulvous. 3| I. long, 1| wide. Middle and 

 Southern States. Head impunctate ; clypeus smooth, semicircular, margin reflexed, 

 with a slight and wide emargination in front, behind which is an indistinct oblong 

 medial fovea; surface elevated at the angles of the emargination : pronotum smooth, 

 an obsolete impression near the anterior angles, which are scarcely advanced ; 

 anterior and extreme posterior margin, and a lateral spot, blackish ; sides scarcely 

 rounded, and with the base, reflexed; posterior angles obtusely rounded; base 

 subrectilinear, distantly bisinuous : elytra with ten well-impressed strise ; interstices 

 smooth and plane. This is nearly as large a species as A. ohlongus Say, but besides 

 differing in colour, the head-and prothorax are not so transverse, and the former is 

 not auriculate. 4-Dej. Cat. p. 162. 



A. oBLONGUs Say. J. Acad. iii. 215. A. hadipes Mels. Proceed. Acad. ii. 135. 

 Middle and Southern States. Dr. Melsheimer gave a new name, because he supposed 

 that of Say to have been applied to a European species by Scopoli and Illiger. The 

 trivial name ohlongus of these authors is, however, itself a synonym of A. rufipes Lin.
