- Structure: Diaspididae referable to the tribe Diaspidini of the subfamily Diaspidinae. Differing from all other members of the family in the fact that the adult female emerges directly from the first stage larva, the second stage usually being omitted. Also differing from all other members of the family in the peculiar development of a portion of the macroducts on the dorsum of the pygidium, these ducts being much enlarged and funnel-shaped, the orifice being very small and the inner extremity much larger, the duct being bent in transverse section so that the inner extremity, if viewed end-on, presents a crescentic form. Scale of the female formed by a mass of felted wax threads which enclose the insect both dorsally and ventrally, the 1st exuviae alone present. Male scale composed of felted threads but of quite definite form, elongate, with the exuviae at one end (Ferris, 1942).
