Remarks

• Structure: The outer scale of female is a thin, transparent, brownish-white cone, about 1 mm in diameter, with a minute yellowish exuvia at the apex; beneath this shell there is a thick, opaque, reddish-brown skin, enclosing the insect; there is a very thin white ventral scale; the outer scale is very similar to the little drops of exuded gum of the host tree, Cupressus macnabiana (Coleman, 1903). Scale of the female elongate oval, composed of the second exuvia, which in undisturbed specimens is covered with wax and is of a gray color; in rubbed specimens the exuvia shows as yellow or red. Scale of the male oval, exuvia nearly central (Ferris, 1938a).
• Biology: Occurring on the needles.
