Genus DRYOBOTA Led. 

 1857. Lederer, Noct. Eur., 100. 



None of the species heretofore described under this generic term 

 belong to it. The small species recently described by myself are bet- 

 ter placed in Cleoceris, as I find by examining the European forms. 

 Mr. Grote's species, antedated by Walker, can not remain here; but as 

 I have no more convenient place for it just now, no change is made.
