Page 217 - Even these of them ye may eat ; the locust after his kind, and the bald locust after his kind, and the beetle after his kind, and the grasshopper after his kind.
Page 223 - ... which are touched with powder, pomatum, and similar substances, every thing made of leather, books, paper, and various other articles, which, if they do not destroy, at least they soil, as they frequently deposit a drop of their excrement where they settle, and, some way or other, by that means damage what they cannot devour.
Page 307 - ... power of separate movement. The maxillary palpi are always six-jointed ; the labial four-jointed ; labium trifid ; wings ample, and provided with many complete cells; females with an ovipositor. It is from the use and appearance of the instrument just named that these insects are called sawflies. It is placed at the extremity of the abdomen of the female on the under side, and is so constructed, that it combines the properties of a saw and auger. It consists of two plates of the same form and...
Page 38 - Though these insects then are the most innocent, perhaps, of all others, they are more cruelly treated or used, than the most mischievous of wild beasts, " As the ephemerus abounds with useful lessons .and moral precepts, so it affords sufficient matter for various speculations. It is engendered, grows to its bigness, and then generates, lays eggs, casts its sperm, grows old, and dies in the space of five hours. This short space comprehends the morning, noon, and evening of its life...
Page 224 - ... is in dark corners, behind all sorts of clothes, in trunks, boxes, and, in short, every place where they can lie concealed. In old timber and deal houses, when the family...

The coronet of hooks converts the membranous or abdominal legs of true caterpillars into efficient instruments of prehension, and they accordingly fix their body by means of them to the plane of position, while the head and anterior part remain free. The abdominal legs of the others, on the contrary, are mere points of support, incapable of clinging to an object, and the larva consequently fixes itself by its pectoral or forelegs, which are much developed for the purpose....
Page 311 - Like the flies they produce, these larvae are sluggish and inactive, seldom moving from the place where they have fixed themselves, unless when requiring an additional supply of food. When not engaged in feeding, or when apprehensive of danger, they roll themselves into a circle, sometimes with the tail elevated in the centre. The greater number live exposed on the foliage of plants, but others take up their abode in the interior of slender shoots and feed upon the immature pith ; others lodge in...
Page 224 - Indies, are, therefore, frequently known by the name of drummers; three or four of these noisy creatures will sometimes be impelled to answer one another, and cause such a drumming noise that none but those who are very good sleepers can rest for them. What is most disagreeable, those who have not gauze curtains are sometimes attacked by them in their sleep. The sick and dying have their extremities attacked, and the ends of the toes and fingers of the dead are frequently stripped of both skin and...
Page 323 - ... alulets, or winglets. They are sometimes of considerable size, and doubtless aid the movements of the wings materially in the act of flying. The use of the halteres, which have been already alluded to as two slender clubbed bodies placed behind the wings, can scarcely be said to be accurately known, but it is conjectured that they assist in giving a proper poise to the body in flight. Some have likewise supposed them to be connected with the function of respiration. They are often of a pale colour,...
