The latter, however I feel certain of hading- in the near future. 
An interesting variety of Limentis archippus , namely Streeker’s 
pseu do-dor ippus has been recently redescribed by John H. Cook, under 
the name of Imithanis. My authority for this statement is W. J. Hol- 
land. I mention this, as a good example of this variety has been taken 
in Dickinson County. 
It would indeed be fortunate if the students of the Lepidoptera were 
agreed as to the nomenclature to be used. There have been two great stu- 
dents of American butterflies, W. H. Edwards and S. H. Scudder, 
each of whom has held different ideas as to classification, especially in 
relation to genera. The result has been two groups of followers and two 
classifications of North American butterflies. I express no preference 
for either, hoping that some day not far off, the Lepidopterists of the 
country can agree upon one set of names. In the present list I have 
followed Skinner, (who represents the Edward’s group of students) 
in Smith’s Check-List of the Lepidoptera of Boreal America..

Species and forms which are known only from the Upper Peninsrla are marked with an asterUk 
2F minus has been recorded from the Porcupine Mountains as gracilis , a misidentification See 
An Ecological Survey in Northern Michigan,” 102. While Grapta gracilis will probably be found in 
the Upper Peninsula, no actual record has yet been made.
