Notes on North American Lepidoptera. 99 



It may seem a wide leap from Leptina to Plusia, but nev- 

 ertheless it appears to be a necessary one ; the naked lashed 

 eyes, the form of the palpi, the unition at the base of the 

 costal and subcostal nervures of the posterior wings, the con- 

 spicuous saddle shaped metathoracic tuft, and particularly 

 the style of ornamentation, admit of no doubt. 



The wings are rounded at the apices, thus differing from 

 our American species, but we do not consider this character 

 of more than specific value, particularly as the European 

 concha and illustris show an approach to this form. 



Plusia Hochenwarthi, Hoch. 



P. alticola, Walk. Cat. Brit. Mus. Noct., p. 912. 



P. ignea, Grote, Proc. Ent. Soc. Phil., Vol. II, p. 274. 



P. alticola, Grote, Bull. Buff. Soc. Nat. Sc, Vol. II, p. 31. 



After comparing numerous specimens of the above species 

 from Europe, Labrador, the White Mountains, N. H., and 

 the mountains of Colorado (Dr. Carpenter) , we agree with 

 Mr. Strecker in uniting under one specific name the forms 

 from these localities. 



The specimens from Colorado are larger and better marked 

 than the others ; we do not see any other differences. 



Mr. Herman Strecker has kindly sent us a specimen of 

 Plusia parilis, Hiibn., so that we are able to verify Mos- 

 chler's record of the species from Labrador. 



Calocampa, Steph. 

 C. nupera, Lintn. 

 C. curvimacula, Morr. 

 C. cineritia, Grote. 

 C. germana, Morr. 



In two recent papers Mr. Grote has made some remarks 

 on this genus, which, as they do not seem to be founded on 

 a careful study of its characters, require correction.
