A couple of clvtra represent this species, which seems to l>e nearly 

 allied to the scarcely smaller 11. lon^iilnin LeC. The humeral anirle i- not 

 (piite SO prominent, and the >tria- and ])unctnn-s are more heavily marked. 

 The stria- are indeed rather deeply impressed and equally >o over the whole 

 width of the elytron, Imt all I.eronie less pronounced and even obsolescent 

 apicallv: the same is true of the punctures which on the liasal half of tin- 

 elytra are very heavv. making trans\-i-r>e creases in the iiei^hltorin^ r inter- 

 spaces, 80 thai they are rather transverse than longitudinal or even circular. 

 The sutural stria is as in 11. lonfrulum, and the texture of the surface of the 

 interspaces, instead of liein^ as in the modern species almost >tnictnrele . 

 is marked with a line Imt decided cross-ribbing, ver^in^ u]on reticulation. 

 The color is a rich carbonaceous with a purplish tin^e.
