One specimen round at New York. This species agrees in the form of the body, as 

 well as in all its generic < baracters with E. cornutus Esch. The punctures of the upper 

 surface are not scabrous, and by the great narrowing of the thorax in front, the form of 

 body, usual in the Elateridte, is at length reached : the last four joints of the antenna 

 together are equal in length to all the resl : tin' third is hardlj longer than the fourth: the 

 fourth joint of the tarsi is not ;it all lobed, and the first joint of the anterior pair is a- long 

 a- the two following united. It is distingui hed from the preceding, as well as the next 



genus, by the plates of tin' posterior coxaa being more suddenly dilated, and truncate | 



teriorly, so that they do not extend farther at the middle than at the internal margin. 



E. cornutus Each., Zool. Atlas 1, 10, tab. I. Mann. Bull. Mosc. (184 . is from Sit- 



kha; it is unknown to me, ami Bcems to differ from the one described above, by its reddish brown colour, 

 with only the head ami thorax black, ami more prominent crest forming a short born.

Pennsylvania, rare: two specimens from Rev. D.Zieglerand Mr. Rath von. The 1 



three joints of the antenna are a- long as the pr< . leaving out the elongated 6rs( 



joint: tin 1 third i- marly twice as long a- the fourth. The general form i- that id' tine 



r, yet, although differing so much in appearance, the distinction of tin- g< nus from 



Emathion is obscure. V I i ting the form of the antenna a- possiblj sexual, and the fourth 



d joint, as it is not lobed in on< of Emathion above described, we find no differ- 



a that, in the pi mi-, the first joint of the anterior tarsi is a- long 



as the three follow i n lt : the fourth joint is two-thirds the length of the third, and i \ lindri- 



cal; and the plates of the p ry much more dilated internally, and at the 



middle extend much farther than al the inner margin.
