OF NATIRAL IIISTOUV. Om 



occurs, of which th.c clytral punctures are much loss dilated, and 

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

 Pennsylvania; Xuttall obtained it in Arkansaw, and Mr. Harahino 

 sent nie ai> individual takin near New Orleans. 



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

 cannot be the rrrnndis Oliv., with which I am now unac<|uainted.

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

 lateral edge. 



Inhabits I'ennsylvania. [180] 



T. t/io/»jsiis 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 tibiic much dilated and compressed. 



Length about one-fifth of an inch.

3. T. SPLENDii)U.s. — Dark brassy; elytra with series of punc- 

 tures, and on the posterior declivity with elevated lines. 



Inhabits United States. 



T. sj>leiidi<fii.< 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 ])Osterior declivity four 

 or iive elevated, converging lines, the exterior one extending 

 towards the humerus; posterior tibiae 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.
