A single elytron, well preserved, appears t<> represent a species i>fTr<>\ 

 of about the size of T. terrestris Say, but with rather slender elytra. The 

 elytron is subequal, narniu iiiir rapidly and regularly at the tip. well arched. 

 and was apparently still more arched originally, the middle portion having 

 a flattened appearance, as if from pressure, with a narrow flattened outer 

 margin; the surface is completely and uniformly covered with thirteen or 

 fourteen equal equidistant rows of frequent dull tubercles, a> distant from 

 one another in the rows as eacli row from its neighbor, and oli-, .lucent 

 toward the apex and the base, especially towards the former. In certain 

 places there is a very slight appearance of greater prominence to every 

 fourth row. which would hardly be notic.-d if it> iv-.-mhlance to modern 

 species of Trox did not lead one to lo,,k for it ; the extreme tip is broken. 

 The color is dark-brown, approaching black, but the whole central portion 

 of a faded brown, nearlv resembling the natural color of the Moiie in which 

 it is preM-rved.
