Tliis larva is said to appear like that of a Chrysomelid beetle. It descends to the surface of the ground and makes a dense silken cocoon, more or less mixed with grains of sand. The most common representative of this family in the Eastern and Middle States is the Spotted Thyris, TJiyris macidata (Thy^ris mac-u-la^ta). This species (Fig. 405) is brownish black, sprinkled with rust- ^s^^"* yellow dots; the outer margin of the wings, -^m especially of the hind wings, is deeply scalloped, ,o<,.—Thyris with the edges of the indentations white. maadata. There is on each wing a translucent white spot; that of the hind wing is larger, kidney-shaped, and almost divided in two. This species occurs also in the West, as there are specimens from Montana in the Cornell University collection. The Mournful Thyris, Thyris liigubris (Thy^'is lu-gu^bris), is a larger species found in the Southern States. It can be recognized by Figure 406. It is brownish black, marked with yellow, ¥\G. ^o6.—Thyris and with the translucent spots yellowish. lugubris. Family SPHINGID^ (Sphin'gi-dae). The Hawk-rnotJis or Sphinxes. Hawk-moths are easily recognized by the form of the body, wings, and antennae. The body is very stout and spin- dle-shaped ; the wings are long, narrow, and very strong ; the antennae are more or less thickened in the middle or towards the tip, which is frequently curved back in the form of a hook ; rarely the antennae are pectinated. The sucking-tube (maxillae) is usually very long, being in some instances twice. Please note that these images are extracted from scanned page images that may have been digitally enhanced
