sinking Pteronus Pzr. as a synonym of it. Pteronus Jrn., 

 however, has precedence by a year over Diprion Schrank, 

 and the former name with Type pini L., designated by 

 Rohwer, should be restored. Pteronus Knw., founded on 

 Jurine's third family of Pteronus in the Nouv. Meth. 

 Hym., which would not be a Pteronus according to the 

 Erlangen List, becomes a homonym and is to be replaced 

 by Pteronidea Rwr. (1911).

" Cephalcia " in the Erlangen List must be a mere 

 misprint, for on two of the Plates (PL 2 and 7 no. 7) which 

 were seen by Panzer, and are described correctly as to all 

 details in his paper, the word is engraved Cephaleia. 

 Panzer afterwards repeated the mistake three times in 

 the Fauna Germanica (868, 86-9, and 87-18), but in the 

 Kritisch Revision he restored the spelling Cephaleia, print- 

 ing the e in a somewhat larger type than the other letters 

 of the word — evidently therefore intending to correct his 

 former spelling. Jurine himself throughout the Nouvelle 

 Methode, both in the text and on the plates, invariably 

 writes Cephaleia. This name one cannot doubt was 

 meant to be derived from Kecpalr), and if so, such a form 

 as Cephalcia is an absolute impossibihty. Cephaleia is not 

 irreproachable, but the objections to it are not so obvious,
