H. Behr. We believe that if he had studied the green Theclas 
from an abundance of material and had given more thought to 
Boisduval’s position, he would never have presented these two 
names, but would simply have amplified Boisduval’s dume- 
torum. 
Thecla afinis Edwards—(From Proc. Acad. Nat. Sci. Phila., 1862, 
223.) 
Expands 1.1 inch. 
Both sexes glossy red brown; brightest in female; the male has a 
smooth oval spot on disc of primaries; costa of primaries and base of 
both wings, blackish brown; whole hind margin edged with same color; 
fringe white; underside uniform apple green, except on inner margin 
of primaries, where it is pale brownish grey; both wings immaculate; 
costal edge of primaries grey; hind margin of secondaries with crena- 
tions. 
Utah, from Mr. C. Drexler. 
Both viridis and affinis are allied to T. rubi and to T. dumetorum of 
Boisduval. The latter, I have not seen, but it is chiefly described as 
being “entirely like rubi, and to be considered a local variety of that 
species,” a description which does not apply to either of the above- 
named species. Affinis approaches most nearly to rubi in color below, 
but the upper side is much brighter and the white spots of underside 
are wanting. Viridis has similar spots to rubi, but the color of both 
sides is different, as is that of the antennae, edge of costa and fringe. 
Thecla viridis Edwards. 
Expands 1.2 inch. 
Upper side of both sexes blackish; the male has a smooth oval spot 
on disc of primaries; hind margin of secondaries a little crenated to- 
ward anal angle; fringe whitish, at anal angle, brown. Under side 
uniform deep green, except on inner margin of primaries, where it is 
brownish grey; costal edge of primaries fulvous; across the green 
shade runs a common sinuous band of elongated, clear white spots; 
fringe of secondaries brown at the extremities of the nervures; anten- 
nae white; club dark brown. 
It has been generally accepted that viridis is a synonym of 
dumetorum. We note in this description of wiridis that the 
upper side is incorrectly given and the spots on under side re- 
late to one of the unusual forms of dumetorum. 
The so-called affinis types came from Utah, where both 
dumetorum and sheridani are found.*
