Dr. Harris, in the manuscript catalogue, refers this species to E. 

 punctipes Say, and also makes it synonymous with E. servus Say. It 

 does not agree in many respects with the descriptions of either of 

 those species ; which are easily distinguished from each other by good 

 characteristics. In one of the males, the second joint of the antenna 

 is longer than the third ; in other respects it agrees with the normal 

 forms of this species. Mr. Say named it for Dr. Harris as P. sei'va.
