Synonymic Notes on Lepidoptera. 



By J. McDuNNoucH, Entomological Branch, Ottawa. 



In Entomological News, xxxii, p. 253, Drs. Barnes and 

 Lindsey gave a few synonymic notes based on figures of some 

 of Boisduval and Guenee's types published by Mr. C. Ober- 

 thiir in Volume XXVII of his Etudes de Lepidopterologic 

 Comparee. 



Through the kindness of Dr. H. Skinner I have been able to 

 examine a copy of the plates of this work and note a few 

 additional changes in synonymy. 



Plate Dili, figs. 4193, 4194, Chdonia dons Bdv. According 

 to the original descriptions Fig. 4194 agrees with doris and 

 Fig. 4193 with ncrca Bdv. The species is, however, not arge 

 Dru. as at present listed, but michabo Grt, and Boisduval's 

 names will take priority. Typical doris has the lines and 

 bands on primaries suffused with pink, whilst ncrca represents 

 the white banded form. 



We have in the Canadian National Collection specimens 

 from Calgary, Alberta, and Aweme, Manitoba, that agree well 

 with ncrea, whilst specimens from Southern British Columbia 

 approach closer to doris. .Michabo Grt., described from Ne- 

 braska, falls to ncrca; mine a Sloss., described from, New 

 Hampshire, is more intensely colored than doris and the name 

 for the present may be held for the Atlantic Coast race. The 

 synonymy will stand : 



doris Bdv. 



form nerea Bdv. 

 michabo Grt. 

 a. mine a Sloss. 



PI. DV, fig. 4217, Acronycta clarcsccns Gn. The species 

 was described from specimens in the Guenee, Boisduval and 

 Doubleday collections, the latter type being in the British 

 Museum. According to the type figured by Mr. Oberthiir and 

 to which we believe the name should be restricted, clarescens 

 is evidently the same species as pruni Harris, but not the spe- 

 cies figured by Hampson (Cat. Lep. Phal., Brit. Mus., VIII, 

 80, PI. CXXIV, fig. 29) which belongs in the inclara group, 

 showing no dark shade line between anal angle and t. p. line.
