SUPPLEMENTARY NOTES. 
Mature Larva. — .7 to .9 inch ; cylindrical; thickened at 3 and 4, the dorsum 
of last segment abruptly curved down to the end; color dark green, the lower 
side, and also feet and legs, pale green; each segment four times creased trans¬ 
versely, and on the flat ridges so caused are rows, one to each, of small tubercular 
flattened points, pale or whitish yellow ; from 2 to 13 a white stripe along base 
just over the spiracles, and above this the ground is yellowish for a little way; 
a medio-dorsal yellow line and sometimes a fine line on middle of side; yellow 
tuberculated points over the legs, in arcs of from 3 to 6 ; on foremost ridge of 
3d segment, high on the side, a dead-black tubercle, a little raised and rounded, 
in yellow ring; spiracles in brown ovals ; surface covered with a fine short down ; 
head obovoid, green, smooth, sparsely pilose ; the ocelli brown. 
Occasionally the larvae in later stages are differently colored. Some have the 
dorsum dark green, edged on either side by a gray line, and successively by a 
band of yellow, a gray line, and a black band; 3 wholly, and 5 partly, black. 
Others are green, with a black band along base of body, and black patches on 3 
and 11; and there is much variation in this way. 
Thecla L^ta. — Figured in vol. i. Until 1882 this beautiful species was 
one of the rarest of its genus. Single examples only were recorded as taken in 
Quebec, Ontario, Maine, New York, West Virginia. I doubt if in all a dozen 
examples could have been found in the collections of butterflies in the United 
States. Therefore I was much surprised at learning that Mr. Morrison found it 
in some abundance at Mt. Graham, Arizona. Its metropolis is in the Southwest, 
and hence its scarcity elsewhere.
