On section ,i , • i r n • of willow leal ^'^^ aiiterior and 5-9 in the posterior group. Median group of circumgenital gland-orifices, 10-25; anterior laterals, 18-35; posterior laterals, 16-24. Scale of Male.—Length, .6 to .8 mm. Oval, without carina^; exuviae pale brown or almost colorless. Eygs.—Dark purple in color. On willow. Chionaspis pinifoliae Fitch. (The Pine-leaf Scale.) Scale of Female.—Snow-white; with bright orange or brown exuviae, shape depending upon width of leaf or host, but usually broadened posteriorly and very convex. Length, 3 to 4 mm.; length of exuvia about 1 mm. Srale of Male.—Length. 1 to mm. The pale yellow exuvia occu- pies aliout one third the length of the tricarinate, posteriorly broadened scale. Female.—Three pairs of well-developed, thin, striate lobes; the median almost circular in outline, entire, separated b}' about one third their width, slightly diverging at the apex and joined anteriorly by an arched chitinous process. Inner lobule of second and third lobes the larger and subtruncate. The gland-spines are arranged as follows: 1, 1, 1, 1, 1-3, becoming shorter toward median lobes. The spines on the ventral surface are short and inconspicuous, situated over mesad of the base of the first, second, third, and fourth gland-spines respectively. Those on the dorsal surface are longer and situated mesad of the corresponding ventral spine. Second row of dorsal pores represented by anterior
