not indented : labium piceous : thorax with a short tubercle on 

 each side : elytra rounded at tip. 



Length less than than one-fourth of an inch. 



This species might perhaps be referred to the genus Lamia. 



[Belongs to Eujwgonms Lee, which is allied to, and perhaps 

 the same as Callia Serv. There is another S. vestita Say, ante 

 1, 193.— Leg.] 



6. S. OBLIQUA. — Elytra with four oblique, elevated lines. 



Body yellowish-brown, or pale ferruginous : head with an im- 

 pressed line ; a broad fuscous line behind each eye : antennae 

 rather longer than the body, gray, incisures fuscous; first joint 

 rather thick, hairy, fuscous : thorax cylindrical, with four fuscous 

 vittae : elytra with numerous, subinequal, irregularly disposed 

 punctures ; four elevated, obtuse, parallel, oblique lines, commenc- 

 ing at the exterior submargin, and proceeding backward to the 

 suture, the anterior originating on the humerus; tip mucronate. 



Length three-fifths of an inch. 



This interesting species was brought by Mr. Thomas Nuttall 

 from Missouri. 



STENOCORUS Fabr. 



1. S. RIGIDUS. — Ferruginous; antennae robust, spinous be- 

 neath. 



Body rather slender, ferruginous, with very short hairs : head, 

 space between the antennae more elevated ; a longitudinal impress- 

 ed line : mandibles at [275] tip black: antennae very robust, 

 hairy, a little longer than the body ; with numerous spines be- 

 neath, particularly on the third or fourth basal joints : thorax 

 rounded, a little narrower before, widest behind the middle : ely- 

 tra very pale ferruginous; without any striae or punctures, instead 

 of which, are very slight depressions, furnishing very short hairs ; 

 on the middle of each elytron is a longitudinal obvious nervure ; 

 tip acutely rounded : thighs, anterior ones more robust than the 

 posterior pairs. 



Length more than three-fifths of an inch. 



The spines on the inferior surface of the antennae, are not 

 confined to the tips of the joints, as in some species, but occupy
