The little larvae remain together until after the third moult, at which time they are about half grown. In the more northern regions where they are found they are now likely to scatter about in search of quarters for hibernation. Having found suitable shelter, they remain through the winter to come forth early the following spring and feed upon the developing leaves of the hackberry trees. They continue to do this for a few weeks before they become full grown. They are then smooth-bodied, greenish worms about an inch and a half long, striped longitudinally in yellow and brown. The hind end of the body is forked in a curious fashion and the head is even more remarkable for the strange pair of tiny antlers projecting from it. These full-grown caterpillars soon change to pale green chrysalids, lightly striped with longitudinal lines of yellow, with a distinctly pointed head. From these chrysalids butterflies emerge early in summer. Evidently in the more Southern states there are two broods of these butterflies each year but there is great need of more precise knowledge in regard to them. As is the case with so many other butterflies there is a dimorphic form, called _ocellata_, in which the outer half of the hind wing is very dark brown, with the eye-spot showing as black with red-brown circles. _Synopsis of the Emperors_ _Goatweed Emperor_ (_Anoea andria_ or _Pyrrhanea andria_). Expanse 2 1/2 inches. Front outer angle of each front wing projecting into a falcate tip. Rear outer angle of each hind wing projecting into a distinct tail. General color burnt-orange with darker marginal bands, and in the female on the upper surface other sub-marginal markings. _Gray Emperor_ (_Chlorippe celtis_). Expanse 2 inches. General color grayish brown with numerous markings of white and blackish. A distinct brown eye-spot on the upper surface of each front wing near the outer hind angle. _Tawny Emperor_ (_Chlorippe clyton_). Expanse 2 inches. General color tawny brown with markings of black and yellowish white. No distinct eye-spot on upper surface of front wings. THE MEADOW-BROWNS OR SATYRS FAMILY _Agapetidae_ The Meadow-browns form one of the most distinctive family groups among all the butterfly tribes. They are characterized, at least so far as our eastern species are concerned, by their slender bodies and rather large wings, toned in various shades of brown, and marked chiefly with conspicuous and characteristic eye-spots. The larger veins of the front wings are swollen at the base. The caterpillars are rather slender and have a curious division of the last body segment into two parts, which gives them an appearance suggestive of the caterpillar of the Emperor butterflies, although the Meadow-brown caterpillars do not have, upon the head, the curious antlers borne by the Emperor larvae. =The Common Wood-nymph or Grayling= _Cercyonis alope_
