219. oldal - Go to the Ant, thou Sluggard, consider her ways, and be wise: which having no guide, overseer, or ruler, provideth her meat in the summer, and gathereth her food in the harvest.
296. oldal - After I had examined one specimen, I attempted to extract a second ; and the reader may imagine how greatly my astonishment was increased, when, after I had drawn it out but a little way, I saw its skin burst, and a head as black as ink, with large staring eyes and antennae, consisting of two branches, break forth, and move itself briskly from side to side. It looked like a little imp of darkness just emerging from the infernal regions.
438. oldal - Kyber even observed that a colony of Aphis Dianthi which had been brought into a constantly heated room, continued to propagate for four years, in this manner, without the intervention of males, and even in this instance it remains to be proved how much longer these phenomena might have been continued.
331. oldal - Fluttering among the olives wantonly, That seemed to live, so like it was in sight; The velvet nap which on his wings doth lie, The silken down with which his back is dight, His broad outstretched horns, his hairy thighs, His glorious colours, and his glistening eyes.
447. oldal - Tamarix mannifera Shr., a large tree growing upon Mount Sinai, the young shoots of which are covered with the females, which, puncturing them with their proboscis, cause them to discharge a great quantity of a gummy secretion, which quickly hardens and drops from the tree, when it is collected by the natives, who regard it as the real manna of the Israelites
176. oldal - Hedychrum lucidulum waits at the mouth of the burrows of these bees, in order to deposit its eggs therein ; and that when its design is perceived by the bees, they congregate together and drive it away. "St. Fargeau states that the females of Hedychrum sometimes deposit their eggs in galls, while H.
197. oldal - Philanthus burrows iu hot sandy situations, and provisions its nests with hive-bees ; a single individual of which, after being stung, is deposited with an egg ; and as each deposits five or six eggs, the number of bees destroyed must be at least equal to that, if not more considerable, which is most probable ; and Latreille counted as many as fifty or sixty females occupied in making their burrows in a space of ground one hundred and twenty feet long.
484. oldal - The larvae are more convex and less flattened than the adults. " DeGeer has made an interesting observation relative to the care with which the females of a species of this family (Acanthosoma grisea), found on the birch, defend their young. In the month of July he observed many females accompanied by their respective broods, each consisting of from twenty to forty young, which they attended with as much care as a hen does her brood of chickens.
203. oldal - The species inhabit sandy districts, in which A. sabulosa forms its burrow, using its jaws in burrowing ; and when they are loaded, it ascends backwards to the mouth, turns quickly round, flies to about a foot's distance, gives a sudden turn, throwing the sand in a complete shower to about six inche's distance, and again alights at the mouth of its burrow.
297. oldal - I could not catch it till it settled on oue, when it ran up and down, its wings in motion, and making a considerable buzz or hum nearly as loud as a sesia : it twisted about its rather long tail, and turned it up like a staphylinus. I put it under a glass and placed it in the sun ; it became quite furious in its confinement, and never ceased running about for two hours. The elytra, or processes, were kept in quick vibration, as well as the wings : it buzzed against the sides of the glass, with its...
