The minuteness and value of these insects have prevented me 

 from ascertaining one or two points with the accuracy I could 

 desire : I hope, however, that some able entomologist may 

 eventually possess ample materials for correcting any error I 

 may have committed and for supplying any deficiencies that 

 may be detected. 



The collar is extremely small, and the pseudelytra are much 

 longer than in Xenos or Stylops; they are fixed very low
