[§ Lophyrus Ltr. is homonymous with Lophyrus Poll (1791) Moll.] 



Pteronus Jrn. in the Erlangen List is defined as the 

 equivalent of Fabricius' third section of Tenthredo {An- 

 tennis pectinatis). That division includes nominally four 

 (really three) species of the genus commonly called Lophyrus 

 Ltr. [this name however is preoccupied in Mollusca by 

 Poll (1791)] — one Monoctenus, and one Megalodontes, to 

 these, in the Supplement, Fabricius adds another, fnrcata 

 Vill., but Panzer (Krit. Rev., 1806) states that the pecuhar 

 structure of the antennae in furcata ^ is not a real pecti- 

 nation, and that they are ciliated as in ustulata and enodis 

 {i. e. as in Tenthredo L. as employed in these notes), and in 

 fact, furcata is much nearer to rosae L. than to any species 

 of the group under consideration. The commonest and 

 best-known of the possible types is pini L., and this species, 

 together with two others (also possible types, but not 

 congeneric with it), have been called by Schrank Diprion, 

 which name Pvohwer has adopted with Type pini L.,
