. Bulletin of the Department of Agriculture. Agriculture; Agriculture. green clover worm. Enlarged THE EGG (FIG. 4) Width milliineter, height millimeter. Subglobose, flattened, cir- cular at the equator, with polar axis about two-thirds length of diameter; 14 to 16 prominent, acute, longitudinal ridges running from base to apex, each alter- nate one slightly longer; interspaces concave and crossed by fine, transverse, regularly placed ridges; polar area sculptured by a few fine ridges; base flattened and taking impression of surface to which attached. Color when laid shiny pale green, sometimes distinctly bluish-green; partly developed eggs with pale orange spots and streaks scattered over upper surface, and in eggs still further advanced with orange spots turned to distinct, sparsely distributed, reddish brown spots. Shortly before hatching the Fig. 4.—Egg egg turns a dark metallic purplish-gray color. The empty shell is colorless, transparent, and iridescent. THE LARVA (FIG. 5) First instar.—Length to 4 millimeters, head width to milli- meter. The newly hatched larva is slender and much constricted between seg- ments. Head considerably wider than body; shiny, transparent, with faint yel- low tinge. Body trans- lucent grayish-white, with alimentary canal slightly darker. As the larva develops the body becomes faintly yellow- ish, usually tinged with green from'chlorophyll in the alimentary canal. Throughout this instar the first three abdominal segments are consider- ably larger than the others; the next four are about equal in size; the eighth, of the same width, is considerably longer; the ninth is shorter and narrower than any except the tenth and last, which is still shorter. The constrictions are deepest between the first four abdominal segments. Prolegs on the third and fourth segments rudi- mentary, those on fifth, sixth, and last functional. Head oblique, somewhat flattened, pale, shiny, transparent, yellowish, tinged wi
