These eggs are de- posited, so far as we have been able to learn, on dried grass and the stems of plants in proximity to the growing plants upon which the young caterpillars are destined to feed. Caterpillar.—The head of the caterpillar when it emerges from the tgg is somewhat larger than the rest of the body, but as it passes successive moults and attains maturity the relative thickness of the body increases, and the adult larva tapers a little from about the middle in either direction. The larvae are pale green or brown, marked by darker stripes upon the back and on the sides, the markings on the sides being in most spe- cies more conspicuous than those on the back. The species all feed on grasses. Chrysalis.—The chrysalids are stout, very slightly angulated, and are formed, so far as we know, unattached, under stones and at the roots of grasses. When pupating, the caterpillar often makes for itself a slight depression or cell in the soil, in which a few threads of silk have been deposited, though not enough to justify us in calling the structure a cocoon. This genus is composed of butterflies which are mainly arctic in their habitat, or dwell upon the
