Head flattened, a double darklateral line, the two connecting with the dark lower edge of the prothoracic shield,which forms a conspicuous lateral line. Head and prothoracic shield copal-browu;front edge of the clypeus whitish, the white extending around the side of the beadabove the eyes.

Y., Professor Comstockfouud this scale quite common ou the lowersurface of the leaves of the hemlock. Scale of female.—The scale of the female veryclosely resembles that of Aspidiotus jiini, exceptthat it is usually more nearly circular. This isprobably due to the difference in the shape of theleaves which the two species infest. The colorof the scale is dark gray, often approaching black,?with the margin lighter, and sometimes with abluish, brownish, or purplish tinge. As with )ini, in many specimens of the fully-formed scalethe part covering the exuvia is more or less dis-tinct, appearing like a small scale with a lightmargin superimposed upon a larger scale. Lengthof scale, to 2™ (.05 to .08 inch); width aboutnine-tenths of the length. Female
