The GELECHIADAE is another large family recently revised by Meyrick (Pro. Linn. Soc. N.S.W. 1904); he says that these moths are not so numerous as in Europe, but as they are such small, inconspicuous insects there are probably a great number still to be discovered. He describes 274 species, of which 207 are new, and 85 of which belong to the Genus _Protolechia_. Several species that infest grain belong to this group: _Gelechia simplicella_, a tiny little brown moth, has pointed slender wings, the fore pair nearly black, with a very distinctive irregular white bar across each apical half. Meyrick has placed it in the Genus _Anacampsis_; it has a wide range over Tasmania and Australia: I have bred it from the foliage of Soy beans, which the larvae matted together and seriously damaged. _Sitotroga cerealella_ is a tiny yellowish brown moth with pointed wings. It has a wide range round the Australian coast, and has been introduced from Europe or America with corn upon which the larvae feed. It is known as the “Angoumois Grain Moth” from the province of that name in France, where in 1760 it swarmed over the country and nearly caused a famine. I have bred it from wheat at Bingara N.S.W. [Illustration: =Fig. 143.=--_Gelechia simplicella_ (Walker). The Soy-bean Moth.] The ELACHISTIDAE were described and revised by Meyrick (Pro. Linn. Soc. N.S.W. 1897), who lists 254 species, most of which were new. He says: “The species of this family are almost all small and therefore often neglected by collectors. Larva with 10 prolegs seldom almost apodal, usually mining in leaves, or amongst seeds or in stems, sometimes case-bearing, rarely amongst spun leaves.” [Illustration: =Fig. 144.=--_Batrachedra sparsella_ (Walker). The larva of which constructs a web amongst, and feeds on, scale insects.] The larvae of the members of the Genus _Batrachedra_, according to Meyrick, feed usually upon seeds. _B. arenosella_, a small dull pale yellow moth with spotted fore wings and grey hind ones, is common over Australia, Tasmania, and New Zealand. The larvae web the seeds and stalks of sedges together, and form a cocoon among the seeds. I have bred a species of _Batrachedra_, _B. sparsella_, Walk., but can find no record of this species in Meyrick’s list. The larva of this moth spins a web on the trunks of trees that are infested with scale insects which they devour, finally forming an elongate cocoon attached to the bark; in the orchard they destroy white louse on oranges, and San Jose scale on peach trees. _Strathmopoda melanochra_, a little brown moth, has the fore wings dull white with metallic reflections and darker markings; the wings are very finely fringed on the hind margins.
