spicuous brown spot, or ocellus, in which are two irregular broken 
lines of a metallic coppery or golden color. The hind wings above 
are grayish brown, becoming darker toward the margin, which bears 
a delicate fringe, at the base of which is a narrow dark line. When 
at rest on the grayish bark of an apple tree, the moth in color so 
harmonizes with its surroundings that it is not readily distinguished, 
and the insect in this stage is perhaps little known to orchardists. 
The egg.—The eggs are small, flat, somewhat oval in shape, and of 
about the size of a pinhead. When recently deposited they are of a

pearl-white color, but become darker with the development of the 
embryo, which after a few days is easily distinguished as a reddish 
ring within the egg. Under a lens the surface is seen to be covered 
with a network of ridges, coarser toward the edge. The eggs of

twigs, comparatively few being placed on the apple, possibly on

fruit, which by this time is much larger and presents a comparatively
