dish cast, next the body being slightly greenish, but lacking the 
brassy reflections of the upper side. A row of small black spots, 
edged externally with gray, run more than half across the upper 
wing from the outer third of the upper margin. A row of three or 
four minute black dots are placed between this row and the outer 
margin. On the lower wings is a row of bold, orange red spots, edged 
internally first with black and then with white, extending from 
the upper margin near the upper angle to near the inner angle. 
A narrow black line runs from the inner angle along the outer 
margin, growing fainter toward the upper angle. A straggling 
row of black dots, edged outwardly with white, partly cross the 
wing beginning about the middle of the upper margin. The thorax 
is bluish gray, the legs whitish. The abdomen is yellowish white, 
but brown at the tip. 
A more agile and wary little butterfly than this it would be 
difficult to find. While on the wing it moves so rapidly and 
darts about in such a manner, that one can hardly keep it in sight. 
Thecla titus. Under side. 
It is frequently to be met with in July, on flowering weeds in com¬ 
pany with other kinds of Thecla , but one must move cautiously 
and strike quickly with the net to capture it. While in pursuit 
of the different species of Argynnis along the meadows, I have 
occasionally run across this butterfly, but have never seen it very 
abundant. French describes the larva as dull green in color and 
covered with very short brown hairs. It feeds on wild cherry 
and plum. Inhabits the greater part of the whole country, but is 
not very common. 
A species not possessing tails, but furnished with several tooth¬ 
like projections on the lower wings, is Thecla irus. The body and 
wings on the upper side are dark brown without markings, save that 
on the lower wings the prolongations are tipped with black, and a
