apex, the disk raised and with a median, shallow groove, reaching 

 neither base nor apex, and a faint impression on each side of the 

 ■ basal part of the groove ; elytra with the sides nearly straight in the 

 male, a little ampliated below the shoulders in the female, little attenu- 

 ated behind, where they are separately rounded, convex and costu- 

 lated with the interstices broadly punctured ; femora bronze-red, tibige 

 and tarsi reddish. 



Differs from E. sculpticollis, in the sculpturing of the head and 

 prothorax, the median groove of which does not reach from base to 

 apex ; there is only one smooth impression on each side of the 

 disk, while in sculpticollis there are two on each side with walls very 

 acute, and lastly the elytra have no dorsal impression.

E. proximus. 



Nigro-ceneus, nitidus, palpis nigris, antennis flavescentibus ; capite 

 postice bi-impresso ; prothorace brevi, lateribus in medio leviter 

 ampliatis, disco obsolete canaliculato ; elytris convexis, sub-costidatis, 

 irtterstitiis punctulatis, in medium disci obsolete iynpressis ; tarsis 

 pedibusque rufescentibus. 



Long. 2£-3, lat. l-lj mm . 



Bronze black with a faint blueish tinge, shining, antennae, pale- 

 yellow, palpi black ; labrum long and broadly incised in the centre, a 

 broad circular impression above the epistome ; prothorax very convex, 

 with a very faint median groove, the lateral sides slightly ampliated in 

 the middle ; elytra convex, elongated, singly rounded behind, convex, 

 with a very faint depression extending on each side of the suture at 

 about the median part of the disk, sub-costated, with the interstices 

 not deeply punctured ; legs and tarsi reddish. 



Allied to the preceding species ; the prothorax is still more 

 smooth and the median groove is nearly obsolete ; the elytra are not 

 quite so deeply punctured in the interstices.
