PINE SCALE-INSECTS. 807 
spots on five abdominal segments, also along each side, and twelve brownish sub- 
dorsal round spots ; under surface uniformly pruinose ; legs black, excepting tibia}, 
which are partly yellowish ; beak long, reaching to the last ventral segment, pale in 
eolor to near the tip, which is black. (Ashmead Can. Ent., xni, 67). 
149. The pine-leaf scale insect. 
Chionaspis pinifolice (Fitch). 
(Plate xxxiii ; figs. 2, 2a, 2d.) 
Scale of female. — The scale of the female is snowy white in color, with the exuviae 
light yellow ; it is usually long and narrow, as represented at Fig. 2 b ; sometimes, 
however, it is broad, as represented at Fig. 2 c. (Scale from leaf of Pinus pallasiana.) 
The shape of the scale apparently depends on that of the leaf to which it is attached. 
Thus on the broader-leaved pines the broad scales are more common. Length of scale, 
about 3 mm (.1 inch). 
Female. — The body of the female is purplish red; the last segment presents the fol- 
lowing characters: 
The anterior groups of spinnerets consists of from seven to ten ; the anterior later- 
als of twelve to twenty; and the posterior laterals of fourteen to eighteen. 
The median lobes are somewhat circular in outline, with their distal ends diverging 
slightly ; there is an arched thickening of the body wall connecting the anterior ends 
of the lobes. The second and third lobes are each deeply incised ; the mesal lobule 
is in each case the larger. 
The plates are long, simple, tapering to a point; there is one laterad of each of the 
three lobes of each side, and one midway between the third lobe and the penulti- 
mate segment. There are elongated marginal pores in the following situations : One 
laterad of each of the first and second plates : one at the base of the mesal lobule of 
the third lobe ; two between third and fourth plates ; and two between the fourth and 
the penultimate segment. 
The spines on the ventral surface are so delicate as to be almost invisible ; their 
bases, however, are easily seen ; they are situated on mesad of the base of each of 
the first, second, third, and fourth plates. The spines on the dorsal surface are quite 
long : the first is near the base of the first lobe, the second between the lobules of the 
second lobe, the third on lateral lobule of third lobe, and the fourth a short distance 
mesad of the fourth plate. 
Scale of male. — White and carinated, as in other species of this genus. 
Male. — Uniformly orange-red; eyes black. (Comstock Ag. Rt., 1880.) 
150. Aspidiotus ? pint, new species. 
Scale of female. — The scale of the female is much elongated, with its sides paralle 
and ends rounded. The exuviae are nearly central, and are covered with secretion. 
The color of the scale is dark gray, often approaching black, with the margin lighter, 
and sometimes with a bluish, brownish, or purplish tinge. In many specimens of the 
fully formed scale the part covering the exuviae is more or less distinct, appearing 
like a small scale with a light margin superimposed upon a larger scale. Length of 
scale, 2 mm -3 mm (.08-.12 inch); width, A mm -l mm . 
Female. — The last segment of the female presents the following characters: 
The spinnerets are more or less elongated, and are arranged in two groups, which 
occupy the position of anterior laterals in other species. Each group consists of from 
eleven to sixteen spinnerets. 
The lobes are quite small; the first and second of each side are abruptly narrowed 
near the distal extremity ; the third lobe is notched once or twice. About one-third 
of the distance from the third lobe to the penultimate segment is a lobe of the lateral 
margin of the body of about the size of the third lobe.
