_Mecyna polygonalis_ defoliates the tree lucerne (_Citysus prolifera_); I have also bred it from broom bushes in gardens at Armidale, N.S.W., and on a native bush (_Templetonia_) in the western plains, so that it has a wide range: Mr. Lyell tells me it is very destructive to the foliage of willows in some parts of Victoria. The caterpillars are slender light green creatures spotted with black and white shaded with yellow on the sides; when full grown they spin a loose silken cocoon. The moth is slightly under 1½ inches across the wings; the fore pair are light brown, and the hind pair each blackish brown round the outer portion and bright yellow in the centre. The two introduced bee moths, _Achraea grisella_ and _Galleria melonella_, belong to a division of this family: the moths lay their eggs about the hive, the grubs crawl in and feed upon the wax which they mat together with silken web, and if overlooked they destroy the whole of the hive; in the days of the old-fashioned hives they were a great source of trouble to bee-keepers, but now with well constructed bar-hives they are easily checked. The first named is of a uniform brown colour with the fore wings rounded; the second has the wings arcuate behind and irregularly mottled. _Aphomia latro_ measures about 1½ inches across its slender somewhat pointed fore wings; is of a general buff colour shot with fine black spots, and divided down the centre of the fore wings with a broad dull white parallel stripe; the hind wings silvery grey. The larvae live in small communities feeding upon and matting together the scape of the flower stalk of the grass trees, in which they pupate within an elongate white silken cocoon. [Illustration: =Fig. 138.=--_Mecyna polygonalis_ (Hubner). The Native Broom Bush Moth.] The Peach Moth, _Conogethes punctiferalis_, is a bright yellow moth thickly mottled with black spots. The larvae attack peaches when ripening, eating and webbing the surface and pupating on the side of the stone. It is common in the northern districts of N.S.W. The “Mediterranean Flour Moth,” _Ephestia kuhniella_, though not an Australian moth, is worthy of note, for it is widely distributed over the country, and causes a lot of annoyance by the bad habits of its larvae of webbing the flour into masses with its silken strands. Another cosmopolitan moth, _Plodia interpunctella_, is known in America as the “Indian Meal Moth,” though it feeds upon all kinds of dried foods; it is a much smaller moth of a general brown tint, the apical portion of the wings much darker than the basal part. This moth also is very common in Australia. Family 16. Bell Moths. TORTRICIDAE.
