We regard the South Dakota and Missouri records of L. appa- 
lachia as somewhat dubious, but they are shown on the map. 
Other records: The following are probably accurate, although the 
specimens have not been seen. They are included on the map: 
Georgia: Thomas Co.: Linton Lake, viii.9.67, viii.29.67 ; Fulton 
Co.: Atlanta (Harris Trail), vii.29.60, viii.20-26.61: De Kalb 
Co.: Avondale Estates, vi. 16.44; Union Co.: Copper Creek 
State Park, vi.6.58, vii. 16.61, vi.18.62, vii. 18.62, viii.22.59; White 
Co.: Cleveland, vi.13.57 (all from L. Harris, unpublished MS, 
p. 244) 
Minnesota: Anoka Co.: Bald Eagle Lake, 1966 (Masters, 1967) 
Indiana: Steuben Co.: Hogback Lake, vii. 17.42 (Price and 
Shull, 1969) 
Tennessee: Madison Co.: Jackson (Mather and Mather, 1958) 
Alabama: Tuscaloosa Co.: vie. Tuscaloosa (Chermock, 1949)

Diagnostic characters 
Color and Pattern . — Lethe e. eurydice and L. e. fumosa differ 
subtly but consistently from L. appalachia. Nearly all specimens 
can be assigned to the correct species by color and pattern alone. 
The most useful characters separating the two species are the 
ground color above and beneath, and the waviness of the postmedial 
line beneath. The two subspecies of eurydice differ most consistently 
in the relative sizes of the forewing ocelli. All of the observed 
differences are given in Table 1. 
We have not seen a truly fresh specimen of L. e. fumosa. Leussler 
(1916) describes the ground color of fresh specimens as “a very 
dark smoky grey . . . even a blackish appearance.” This sounds 
very much like the color of newly emerged appalachia. Old speci- 
mens of the two are very different, however: fumosa males are 
an even, somewhat purplish or reddish brown, while appalachia is 
grayish or mousy brown. Some female fumosa , particularly from 
Colorado, are nearly identical in color to nominate female eurydice , 
but the ground color of the males is nearly always distinctive. A few 
male eurydice from the northeast are dark purplish brown when
