100 Notes on North American Lepidoptera. 



Ill the first of these papers from the Bulletin of the Buf- 

 falo Society of Natural Sciences, Vol. II, pp. 193-200, soli- 

 daginis and germana are separated under Hiibner's genus 

 Lithomia ; we prefer to follow Lederer and all succeeding 

 European Lepidopterists, and place these species in Calo- 

 campa; they resemble strongly in ornamentation the typical 

 species, and their only material structural difference is in the 

 less arched, more rounded collar. 



In the second paper from the Proceedings of the Philadel- 

 phia Academy of Natural Sciences, p. 210, 1874, Mr. Grote 

 takes exception to our statement that nupera is the repre- 

 sentative of the European vetusta, and considers it rather to 

 resemble the allied species exoleta. 



After a reexamination of our material, consisting of six- 

 teen specimens of exoleta and eight of vetusta from various 

 parts of Europe, and five specimens of nupera and fifteen of 

 curvimacula from different localities in the Eastern and Mid- 

 dle states, we not only feel prepared to state again that nu- 

 pera is our representative of vetusta, but further that it is 

 still a matter of doubt whether the forms are specifically 

 distinct. 



If a series be examined it will be seen that every spot and 

 line of vetusta is reproduced in nupera in exactly the same 

 relative position ; the black basal dashes, the strongest dis- 

 tinctive character, are found in the same place in both spe- 

 cies, in the former brownish and nearly concolorous, in the 

 latter accentuated and marked by black scales ; we now know 

 of no other constant distinguishing character than this ; 

 which is, as we have shown, merely a difference in intensity, 

 not one of position. 



In regard to the statement that nupera is more closely al- 

 lied to exoleta we remark in addition to what is said above, 

 that the former differs mainly from the latter in the obsoles- 

 cence of the orbicular spot, and the presence of a single in- 

 tense black dash beyond the reniform, or in other words pre-
