the mandibles are short, unarmed, ciliated on the interior and 

 exterior sides, and not [210] prominent ; the labrum also is con- 

 cealed ; the labium is conical and prominent, and the tongue is 

 concealed. The extremity of the clypeus has very much the ap- 

 pearance of the labrum, as the elevated and dentated Hue resem- 

 bles a reflected termination of the head. 



A single specimen was brought from the x\rkansa by Mr. 

 Thomas Nuttall.

GEOTKUPES Latr. 



1. Gr. EXCREMENTi. — Black-bronzed, mutlc; an impressed rec- 

 tangular line on the clypeus. 



Inhabits the United States. 



Scarahseus excrementi Knoch in Melsh. Catal. 



Body above black bronzed, punctured ; beneath dark violace- 

 ous : clypeus confiuently punctured ; summit destitute of punc- 

 tures ; three very obtuse slightly elevated tubercles, of which one 

 is above each eye, and consists of a more elevated portion of a 

 raised line, which passes from above the eye to the edge of the 

 clypeus, another tubercle is situated upon the middle ; a pro- 

 foundly impressed, abbreviated, longitudinal line between the 

 eyes, which divaricates anteriorly into two lines that terminate at 

 the tip of the elevated lateral line : thorax densely punctured 

 each side, punctures rare on the dish ; an impressed longitudinal 

 obsolete line, from the base to the middle; an indented, obsolete 

 spot on the lateral submargin, distinguished by more dense punc- 

 tures; elytra profoundly striate, striae slightly crenate on the 

 inner sides. [211] 



Length about eleven-twentieths of an inch. 



This species is common in various parts of the United States. 

 It is found in Pennsylvania, and I obtained specimens at Engineer 

 Cantonment, and at Cape Gerardeau. 



The tubercles of the head are not more distinct than those of 

 S. stercorarius. 



It strongly resembles S. sjilendidus of Fabr., miarojihagus of 

 Knoch, but differs from both in color, and from the latter, which 

 it more closely resembles, by having the thoracic punctures less 

 numerous, not so much dilated or so profoundly impressed ; the
