INSECTS : WINGS AND THEIE APPENDAGES. 83 would appear cut into saw-like teeth. Along the margins of these ridges are set minute sockets, which are very dis- tinctly seen, where the scales have been displaced; in these the tiny foot-stalks of the scales are inserted. The little Beetles with which we are familiar under the name of Weevils, characterised by their long slender snouts, at the end of which they carry curiously folding antennae, and which constitute the family Curculionida, are in many cases clothed with scales, to which they owe their colours and patterns. Several of our native species display a green or silvery lustre, which under the micro- scope is seen to be produced by oval scales. But these are eclipsed by the splendour of many tropical species; especially that well-known one from South America, which is called the Diamond Beetle, and scientifically Entimus imperialis, from its unparalleled magnificence. A piece of one of the wing-cases of this beetle is gum- med to the slide now upon the stage. We look at it by reflected light with a magnifying power of 130 diameters. We see a black ground, on which are strewn a profusion of what look like precious stones blazing in the most gorgeous lustre. Topazes, sapphires, ame- thysts , rubies, eme- ralds, seem sown broadcast; and yet not wholly without regularity, for there are broad bands of the deep black sur- face, where there are no gems, and, though at consider- able diversity of angle, they do all point with more or less precision in one direction, viz., that of the bands. g 2.
