. The life of North American insects [microform]. Insects; Insectes. *ll 136 NORTH AMERICAN INSECTS. ii^iijii this dust has regular forms, and consists of horny scales, fostened in the wings. From this circumstance the order of entomology comprising Moths and Butterflies is called Lepidoptera, which signifies in English " ; The head of these insects is provided with two large glob- ular eyes, covered with a horny skin, which under the mag- nifying glass looks like a net-work, consisting of a number of elevated points or convexities, of which each one may, perhaps, be considered a single eye. This horny skin is transparent, and when taken oif and looked through, for mstance, at one man, there are presented to us a whole army of Liliputians. But in spite of this multifarious vi- sion, the insect probably sees only that object which is in the direct angle of vision, or which is in a straight line with its point of sight. Figure 28. ii-i m- ill:,. Saturnia lo.—Female. On the upper part of the head, between the eyes, are seen two thread-like filaments, called "feelers," antennc^, as in the Saturnia lo (Figs, 27 and 28), and in the Astmm (Fig. 30). The use of these organs has not yet been exactly :i'l.
