The material of,.. some of them is diaphanous, and as if cellular or divided by scales. The caterpillars of the true Tinere, commonly called Moths, clothe themselves with particles of woollen stuffs, which they cut with their jaws and on which they feed, hai1·s of furs, and those of the skins of animals in zoological collections, united by silk: They know how to lengthen their sheath, or to increase its diameter by slitting it and adding a new piece. In these tubes they undergo their meta-morphoses, after closing the orifices with silk. Those, who wish to become well acquainted with the manner in which they construct these habitations, and to acquire a knowledge of their various forms and materials, must have recourse to the Me· moirs of Reaumur, Rresel and De Geer. The Pseudo-Tinere content themselves with mining the interior of the vegetable and animal substances on which they feed, and forming simple galleries, or if they construct sheaths either with those matters or silk, they are al wa.ys fixed, and are mere places of retreat. These caterpillars, which perforate in various directions the pa-renchyma of the leaves on which they feed, have been called .Mineuses or Miners. They produce those desiccated spaces in the form of spots and undulating lines, frequently observed on leaves. Buds, fruits, and seeds of plants, frequently those of wheat, and even the resinous galls of certain Coniferre, serve for aliment and habitations to others. These Insects are frequently ornamented with the most brilliant colours. In several species the superior wings are decorated with golden or silver spots, sometimes even in relievo. Some, in which the four pal pi are always distinct( 1 ), exposed, or merely partly concealed (the superior ones) by the scales of the ely· peus, salient, and of a moderate size, resemble Phalrenre-P.wra· lides, L.;-their tectiform wings most frequently flattened, or but slightly raised, form an elongated triangle or sort of delta. Sometimes the proboscis is very apparent, and serves for its ordi· nary use. The caterpillars of these species live on various plants. (1) The Yponomeutz, one or two excepted, <Ecophorz and Adela: are almost the only Tineites whose maxillary pal pi are not very apparent, but as they may be concealed by the inferior ones, and as it is very difficult to establish in this respect a fixed and rigorous line of demarcation, we have not thought proper to divide the Tineites according to the number of those organs. M. Savigny, in his Memoirs on the invertebrate animals, has published some figures in which they have various proportions. The new genera, which he merely mentions, are un· known to us.
