OF NATURAL HISTORY. 653 



occurs, of which the elytral punctures are much less dilated, and 

 the thorax is less deeply sculptured. I have found the species in 

 Pennsylvania ; Nuttall obtained it in Arkansaw, and Mr. Barabino 

 sent me an individual taken near New Orleans. 



A label, attached to a specimen in my cabinet, states that it 

 cannot be the crenatm Oliv., with which I am now unacquainted. 



[Belongs to Omorgui^, and was previously described as T. 

 punctatus Grerm. — Lec] 



2. T. GLOBOSUS. — Blackish-bronze; elytra denticulated on the 

 lateral edge. 



Inhabits Pennsylvania. [180] 



T. glohosns Melsh. Catal. 



Body blackish-bronze, punctured : head entire, unarmed ; thorax 

 with an impressed line on the anterior lateral submargin : elytra 

 with oblong, deeply impressed, rather distant punctures; posterior 

 declivity with four or five elevated, converging lines, the two exte- 

 rior ones continued towards the humerus ; exterior edge with numer- 

 ous, approximate teeth : posterior tibire much dilated and compressed. 



Length about one-fifth of an inch. 



[Belongs to Ac an f hoc er us. — Lec] 



3. T. SPLENDIDUS. — Dark brassy; elytra with series of punc- 

 tures, and on the posterior declivity with elevated lines. 



Inhabits United States. 



T. splendidm Melsh. Catal. 



Body rather short, oval, polished, dark bronze ; punctured : head 

 unarmed, entire : thorax with an impressed line on the anterior 

 lateral submargin : elytra with regular series of rather long, deeply 

 impressed, approximate punctures ; on the posterior declivity four 

 or five elevated, converging lines, the exterior one extending 

 towards the humerus; posterior tibise much dilated and impressed. 



Length nearly one-fifth of an inch. 



Readily distinguishable from the preceding by the more approxi- 

 mate punctures of the elytra, and the simplicity of the lateral 

 edge. They both exhibit a remarkable difference, in their smooth 

 surface, from the greater number of the species of this genus. 



[Also an Acanthocerus, previously described as Melolontlia 

 aphodioides Illiger, and Scarabseus latipcs Germ., and subse- 

 quently as A. Isevistriatiis Lap. — Lec] 

 1835.]
