One of the characteristic features of this group of eggs is that each egg is surrounded in a more or less regular manner bv a circlet of long hairlike scales derived from the caudal end of the female's abdomen. This gives the mass of eggs an appear- ance of having acquired a growth of mold. An examination of the females in the region of the ovipositor discloses a ven,' heavv investiture of these light tan colored hairs. Egg. .82 mm. in diameter x .4 mm. high.

Echinoid, white. !Micropyle depressed, .15 mm. in diameter, with a crater-like rim. The surface is covered with a reticula- tion of hexagonal cells, or pits, having raised walls, the junctures of which are not tipped with projections as in manv of the L}xaenid eggs. These cells are largest on the outer circumference of the egg, and become progressively smaller as they approach the mi- cropyle. Plate 6 figures a group of eight of these eggs, viewed from their superior surfaces. The earlier instars of the larva remain to be described and PLATE 7 Mature larva of Enargia decolor Wlk., on leaf of aspen. Enlarged approximately x 3. Photo by the lat€ Wm. Menke. 20.
