* I am informed, April 10th, 1872, by the author of the "Geschied- 

 kundig Overzigt vanbet Geslacht J.cenirojous," that a continuation thereof 

 is in the hands of the editors of the " Tijdschrift voor Entomologie." 



And in the " Petites Nouvelles Entomologiques " for April 15th, is a 

 note by Eitsema, in which the author reiterates the opinion that there 

 are but two known species of Acentro'pus, A. niveus and A. latipennis, 

 "the latter having been met with only in Southern Eussia." From what 

 has been said above, it will be seen that this is not correct ; A. latipennis
