PERINEURA, Htg. 

 Obs. Hartig formed his genus Perineura for Tenthreclo rubi, Pz., 

 female, while he made another genus (Synaerema) for the male of that 

 insect. Thomson retains Synaerema for rubi, and Perineura for the 

 T. instabilis group of Klug, as well as for T. lateralis and T. gibbosa, and 

 also T. viridis, scalaris, and imnctulata; making, as it seems to me, a 

 more unnatural genus of it. I retain Perineura for the "instabilis'^ 

 group, the others I place in Tenthredo. In the nomenclature of the species 

 I follow Thomson, as it seems impossible to know what species are meant 

 by employing the older names. Costa formed a genus, Tenthredopsis 

 for instabilis.
