Descriptions of Five New Species of Scale Insects, with Notes

Scale of female.—The general shape of the scale of the female is nearly circular (see Plate XXIX., Fig. 1, 5), but it varies according to the position of attachment, as scales under a fold in the bark or on some uneven surface are very irregular in outline. The color is dirty grayish in fresh specimens, but darker when driel. The exuviae are usually slightly to one side of the center, and covered with excretion; the nipple-like prominence in rubbed specimens is reddish or yellowish brown, surrounded by a band a little darker than the margin. Scale rather convex, delicate, and easily torn when removed from fresh material. It varies considerably in size, the average diameter being about 2 mm.Ope
