under frontal elevatiou.s ; second joint more robust than the third, 

 and equally long ; fourth joint rather lon^^er than the third ; re- 

 maining joints obconic, subequal, the last a little lon;^er : piilpi, 

 terminal joint oval : thorax transverse ([uadrate, with punetures 

 like those of the head, but not much confluent; anterior an<^le8 

 rounded ; lateral edges nearly parallel, very slightly contracted 

 towards the posterior angles, which are nearly rectangular, a little 

 acute, not contiDucd backward beyond the line of the base : ely- 

 tra with punctured stria) and minutely punctured interstitial 

 lines : pectus with less crowded punctures than the thorax : [187] 

 middle segment very broad; no groove: fcot, like all beneath, 

 dark pieeous : tarsi a little paler. 



Length over one-fourth of an inch. 



This species is not perhaps in all its characters perfectly coin- 

 cident with those of the genus, particularly in the remote origin 

 of the antenna) ; but the form of the praj-itcruum and the great 

 inflection of the head agree very well.

5. E. FRONTOSUS. — Antenna) submoniliform ; thorax indented 

 each side of the middle. 



Inhabits Indiana. 



Body blackish piccous, with short yellowish hair, punctured : 

 front longitudinally indented: antenna) ferruginous, serrato- 

 moniliform ; basal joint arcuated, obliquely truncated at tip; 

 second joint arcuated at base : thorax with a longitudinal im- 

 pressed line, and an indentation each side of the middle; poste- 

 rior angles prominent : elytra, striie not deeply impressed : feet 

 pieeous. 



Length one-fifth of an inch. 



The very short and submoniliform joints of the antenna;, as 

 well as the general form of the body, give to this species a re- 

 setublance to the monificonus ^Llnnerh., but the thoracic inden- 

 tiitions, «tc., distinguish it. 



[Belongs to Emathion, and was afterwards described by mc as 

 Epiphanis canalicuhitus. — Lkc]

 indentation instead of a recipient cavity, may perhaps be placed
