Its larva feeds upon white birch. Pla- typteryx genicula (P. ge-nic^u-la), another eastern species, re- sembles the preceding, but differs in being of a light ochre- yellow color and in the course of the wavy lines on the front wings. A third similar species occurs in California; this is Platypteryx siculifera (P. sic-u-lif'e-ra). Family CvMATOPHORlDiE (Cym-a-to-phor'i-dae). The Cyinatophorids iCym-a-toph'o-rids). The Cymatophoridse include moths of medium size, with elongated wings. The front wings are usually slightly widened at the inner angle (Fig. 348), and in our more common species are conspicuously marked with wavy or zigzag lines. The antennae are filiform and more or less velvety or pubescent in the male, and the maxillae are well developed. The moths fly by day, and when at rest fold their wings yig.'i^^.-Thyat^ra scripta. roof-like upon the abdomen. The venation of the wings is illustrated by Figure 349. The important features to be noted are the following: In the front wing vein Vj arises midway between veins Vj and V3; while in the hind wing vein V^ arises much nearer to V3 than to V,. In the hind wing the subcosta and radius are distinct, and vein V^ is joined to radius by a comparatively.
