Arctornis pellucidoides sp.
Arctornis pellucidoides (paratype)
15-17mm. The facies of the wings is reminiscent of
that of A. pellucida Swinhoe comb. n. (N.E. Himalaya) being
yellowish, uniform, rather translucent, with a small black discal dot on the
forewing. The yellow tone is slightly more intense however. The scales are
mostly of the narrow, forked type. The fringes are tinged slightly browner.
There is a broad rufous bar on the frons between the antennae. The legs and
palps are not marked. The male genitalia differ markedly from those of pellucida,
being relatively much smaller, with shorter valves, though the uncus is
longer and narrower. There is a strong saccus, and the harpe on the valve is
broader, though tapering rather than clubbed at the apex.
