*Borner (1932:612) says xyl/oste: Schrank is sii (Koch). If this is true Davidson’s spe- 
cies is probably distinct since is does not show the dark dorsal markings described 
by Koch. After this manuscript was sent to the printer Borner’s latest work (1952. 
Europae Centralis Aphides. Heft 4 und Mitt. Thuringischen Bot. Gesellschaft, Beiheft 
3) came to hand. Borner states (p. 113) that xylostei Schrank is “‘sii CB. 1931/32 non 
Koch 1855.’’ This statement removes the doubt of identity of Davidson’s species with 
Schrank’s. Also, Hottes has just called attention to the new name, hyadaphis, given by 
Kirkaldy (1905:416) for xylostei Schrank. This name would take precedence.
