Resembles N. ustulatus Fabr., and therefore probably is a No- 

 taphus Meg. 



12. B. OPPOsiTUM Say. — Resembles the maculatum Gyll., and 

 probably [439] belongs to Lopha. The sutural stria is impressed 

 from the middle of the tip. It is somewhat bronzed. 



13. B. EPHIPPIATUM. — Pale testaceous ; elytra with punctured 

 striae and a large common blackish spot. 



Inhabits Indiana. 



Body pale testaceous or honey-yellow ; antennae paler than the 

 head, a little darker towards the tip; palpi color of the antennae ; 

 thorax widest before the middle, gradually contracting by an al- 

 most rectilinear, but hardly perceptible concave line, to the basal 

 angle, which is rectangular ; dorsal line but slightly impressed, 

 obsolete before ; basal lines hardly distinct from the depressed 

 basal margin, which is minutely wrinkled ; elytra with impressed, 

 punctured striae, obsolete at tip ; seventh stria wanting; third in- 

 terstitial line with two small orbicular punctures, one before the 

 middle and the other a little behind the middle ; a very large 

 common blackish spot on the middle, within which the suture is 

 reddish-brown ; suture behind the spot blackish ; a small, obso- 

 lete blackish spot at the base each side of the scutel ; feet pale 

 yellowish. 



Length one-tenth of an inch. 



At first view it resembles proximum Say, both as respects size 

 and color, but it may be distinguished by many characters, of 

 which the punctured strijB is one.

14. B. TRipuNCTATUM.— Piceous; elytra with five abbreviated 

 striae ; thorax three-punctured between the dilated basal lines. 



Inhabits Indiana. 



Body piceous; head and thorax darker; antennae light brown- 

 ish, paler at base ; palpi pale yellowish ; thorax with the dorsal 

 line distinct, terminating on the basal margin in an impressed 

 puncture, on each side of which is another rather smaller punc- 

 ture; basal lines much dilated, deeply undulating the posterior 

 edge of the thorax; elytra with about five rather obtuse 

 striae, not extending to the tip or base ; sides destitute of striae
