The cell of the primaries and of the secondaries is lightly closed. Egg.—The egg is ovoid, nearly twice as high as wide, with nar- row vertical ridges on the sides, every other ridge much higher than its mate and increasing in height toward the vertex, where they ab- ruptly terminate, their extremities ranging around the small de- pressed micropyle. Between these ridges are minute cross-lines. Caterpillar.
. The butterfly book [microform] : a popular guide to a knowledge of the butterflies of North America. Butterflies; Papillons. Qcnut Libythea the third median nervule is the most pronounced. The cell of the primaries and of the secondaries is lightly closed. Egg.—The egg is ovoid, nearly twice as high as wide, with nar- row vertical ridges on the sides, every other ridge much higher than its mate and increasing in height toward the vertex, where they ab- ruptly terminate, their extremities ranging around the small de- pressed micropyle. Between these ridges are minute cross-lines. Caterpillar.—The caterpillar has the head small, the anterior segments greatly swollen and overarching the head. The re- mainder of the body is cylindrical. Chrysalis.—The chrysalis is of a somewhat singular shape, the abdomen conical, the head sharply pointed, a raised ridge running from the extremity of the head to the middle of the first abdominal segment on either side, and between these ridges is the slightly projecting thoracic tubercle. On the ventral side the outline is nearly straight. The caterpillar feeds upon Celtis occidentalis. Three species are reckoned as belonging to our fauna. It is, however, doubtful whether these species are in reality such, and there is reason to believe that the three are merely varietal forms or races, no struc- tural difference being apparent in any of them, and the only dif- ferences consisting in the ground-color of the wings. (i) Libythea bachmanni, Kirtland, Plate XXVIll, Fig. i, i ; Fig. 2, i, under side; Plate V, Figs. 23, 24, chrysalis (The Snout-butterfly). 5M//^r/i[y.—Easily distinguished from the following species by the redder color of the light spots on the upper side of the wings. Expanse, inch. Early Stages.—The generic description must suflFice for these. They have been frequently described. The butterfly ranges from New England and Ontario south- ward and westward over the whole country as far as New Mexico and Arizona
