Spermophagus vivifioatus. 



PI. XI, fig. 6. 



Spermophagm vivificatu-s Scudd., Bull. U. S. Geol. Geogr. Surw Ten-.. II, 82 (1876); 

 in Zittel. Handb. Palieont. (I), II, 792, tig. 1019 (1885). 



Tw(i specimens, reverses, but one showing more plainly the upper, the 

 other the under surface, were found by Mr. T. L. Mead. They are in an 

 unusually good state of preservation. But verA' little of the small head 

 can be seen, either upon the upper or the under surface ; the jjortion exposed 

 is delicately punctured, the jjuuctures being closely crowded, and rather 

 less than 0.01 mm. in diameter. The antennae show nine joints, which are 

 together longer than the breadth of the prothorax; the first and second 

 joints are ovate, the remainder more or less obconical; the first four are of 

 nearly equal length, and of about equal length and breadth; beyond, the 

 joints are subequal among themselves, but much longer than broad. The 

 prothorax is crushed and although not displaced, it is difficult to determine 

 its exact form, or whether or not it wholly concealed the head from above. 

 It is more coarsely punctate than the head, the punctures being 0.025 mm. 

 in diameter: the posterior border is broadl}^ angulate, the angle rounded, 

 the outer margin more or less rounded, and the whole prothorax broadest 

 posteriorly. The elytra are \ev\ ample, equal, each independently very 

 broadly and regularh'- rounded at the apex, which does not reach the tip of 

 the abdomen: they are very distinctly but narrowl}^ punctato-striate, in 

 nine straight, equidistant, complete rows, besides an auxiliary row next the 

 outer margin for a poi-tion of the distance; near the tip of the elj'tron the 

 outer and inner rows curve toward the middle of the apex and all fade out 

 before reaching it; the entire border of the elytra is marginate. The 

 femora, especially the hind pair, are stout; the hind tibise are considerably 

 shorter than the femora and there are, apparently, on one side, faint indica- 

 tions of the two long- tibial spurs, with which the apex of the hind tibiae is 

 armed in this genus. The abdomen is exceedingly shoi-t and broad, the 

 apical segment protruding- a little beyond the others and well rounded. 



Length of body, 5.25 mm.; breadth of prothorax, 2 mm.; of bod)' at 

 middle of elytra, 3.25 mm.; length of antennae, 2.2 mm.; of elyti-a, 3.75
