. Australian insects. Insects. 282 LEPIDOPTEEA. Botanic Gardens Sydney. Thudaca ohliqueUa, about 1 inch across the wings, is a beautiful little silvery white moth, with the fore wings deep yellow thickly marked'with parallel and transverse bars of silvery white; the hind pair broad, silvery, lightly clouded, and fringed behind with long plumes. The Epipyropidae comprise a small group of moths that have been raised to the rank of a family by Perkins (Bulletin I. part 2, ''Leaf Hoppers and their Natural Enemies," Hawaii 1905), though it would probably be more correct to place them as a sub-family of the Tineidae. Sharp (Cambridge Natural History: Insects part II.) places them in the Limacodidae. They are small black, grey or brown moths, with small eyes; no ocelli; the palpi wanting or very minute, and the mouth parts little developed. They have remarkable parasitic habits in the caterpillar state living upon the backs of different leaf hoppers (Homoptera) and feeding upon the waxy or sugary secretions discharged by their hosts. Perkins describes 7 new Australian species, which are placed in three genera, based on the neuration of the wings. Three species come from Cairns, N. Queens- land, and four from the neighbourhood of Sydney. Heteropsyche mclanochroma measures under 1/2 an inch across the outspread wings and is of a general black or fuscous colour with purple tints on the fore wings. Koebele records it as common about Sydney, parasitic upon a number of different Fulgorids and Jassids. Rothschild (Novitates Zoologicae 1906) has named another species, Epipyrops doddi, after the well known collector, P. F. Dodd, who had worked out its life history in North Queensland.
