To these follow the tanagers (Tanagridae), with upwards of forty genera (only one of which crosses the border), and about 300 species; the piculules (Dendrocolaptidae), with as many genera, and over 200 species; the ant-thrushes, (Formicariidae), with more than thirty genera, and nearly 200 species; together with other groups which, if not so large as those just named, are yet just as well defined, and possibly more significant, namely, the tapaculos (Pteroptochidae), the toucans (Rhamphastidae), the jacamars (Galbulidae), the motmots (Monotidae), the todies (Todidae), the trumpeters (Psophiidae), and the screamers (Palamedeidae); besides such isolated forms as the seriema (Cariama), and the sun-bittern (Eurypyga).

An ant is easily recognized both by the casual observer and by the student of insects.
Perhaps, however, the name may only signify a large terrestrial biting apterous insect, surpassing the ant in size and predatory habits.
So the text "the myrmekoleon bath perished for that he had no nourishment" set them pondering, and others reproduced their meditations, with the following result: "The Physiologus relates about the ant-lion: his father hath the shape of a lion, his mother that of an ant; the father liveth upon flesh, and the mother upon herbs.
On patting their carrier or some passing ant, the mites are supplied with food, no service being rendered by them in return for the ants' care.
It may be added that there are some marsupials, such as the wombat, koala, marsupial ant-eater and the dasyures, FIG.
In 1075 he caused the investiture of ecclesiastica dignitaries by secular potentates of any degree to be condemned These two reforms, striking at the most cherished privileges ant most deeply-rooted self-indulgences of the aristocratic caste ii Europe, inflamed the bitterest hostility.
The wood ant (Formica rufa, fig.
The workers of a Ceylonese ant (Oecophylla smaragdina) are stated by D.
Others again play the part of thieves in the ant society; C. Janet observed a small bristle-tail (Lepismima) to lurk beneath the heads of two Lasius workers, while one passed food to the other, in order to steal the drop of nourishment and to make off with it.
Formica sanguinea is a well-known European slavemaking ant that inhabits England; its workers raid the nests of F.
From all other members of the family the marsupial, or banded, ant-eater (Myrmecobius fasciatus) differs by the presence of more than seven pairs of cheek-teeth in each jaw, as well as by the exceedingly long and protrusile tongue.
The South African sub-region has a flora richer perhaps in number of species than any other; and these are often extremely local ant restricted in area.
ANT-LION, the name given to neuropterous insects of the family Myrmeleonidae, with relatively short and apically clubbed antennae and four large densely reticulated wings in which the apical veins enclose regular oblong spaces.
Strictly speaking, however, the term ant-lion applies to the larval form, which has been known scientifically for over two hundred years, on account of its peculiar and forbidding appearance and its skilful and unique manner of entrapping prey by means of a pitfall.
Slipping to the bottom the prey is immediately seized by the lurking ant-lion; or if it attempt to scramble again up the treacherous walls of the pit, is speedily checked in its efforts and brought down by showers of loose sand which are jerked at it from below by the larva.
The pupa stage of the ant-lion is quiescent.
And these bring forth the ant-lion, a compound of both, and in part like to either, for his fore part is that of a lion, and his hind part like that of an ant.

The -fact that the name of the ant has come down in English from a thousand years ago shows that this class of insects impressed the old inhabitants of England as they impressed the Hebrews and Greeks.
- Wood Ant (Formica rufa).
The head of an ant carries a pair of elbowed feelers, each consisting of a minute basal and an elongate second segment, forming the stalk or "scape," while from eight to eleven short segments make up the terminal "flagellum."
- Ant-colonies are founded either by a single female or by several in association.
The seeds are harvested from various grasses, especially from Aristida oligantha, a species known as " ant rice," which often grows in quantity close to the site selected for the nest, but the statement that the ants deliberately sow this grass is an error, due, according to Wheeler, to the sprouting of germinating seeds.
Each kind of ant is so addicted to its own particular fungal food that it refuses disdainfully, even when hungry, the produce of an alien nest.
Sanguinea can live either with or without slaves, but another European ant (Polyergus rufescens) is so dependent on its slaves - various species of Formica - that its workers are themselves unable to feed the larvae.
- Ant, Tetramorium cespitum (Linn.).
Fielde show that an ant follows her own old track by a scent exercised by the tenth segment of the feeler, recognizes other inmates of her nest by a sense of smell resident in the eleventh segment, is guided to the eggs, maggots and pupae, which she has to tend, by sensation through the eighth and ninth segments, and appreciates the general smell of the nest itself by means of organs in the twelfth segment.
C. McCook, Agricultural Ant of Texas (Philadelphia, 1880); and A.
1895) is the great authority on ant-guests and associates.
Ant-eaters (Orycteropus capensis), porcupines, weasels, squirrels, rock rabbits, hares and cane rats are common in different localities.
It is not uncommon to find once cultivated fields abandoned because of their ravages and to see large campos completely covered with enormous ant-hills.
One of the characteristic orders of the Brazilian fauna is that of the Edentata, which comprises the sloth, armadillo and ant-eater.
The range of the sloth is from the Guianas south into Minas Geraes, the armadillo as far south as the Argentine pampas and the ant-eater from the Amazon south to Paraguay, though it is found in the Amazon region principally.
The ant-eaters (Myrmecophaga) are divided into three or four species, one of which (M.

Echinodiscus lives in the intestine of ant-eaters: G.
Mr Cook also found that the boll weevil was attacked, killed and eaten by an ant-like creature, the " kelep."
The number of eggs produced at a time varies enormously according to the species, from about half a dozen, more or less, in some ant-mimicking Attidae or jumping spiders to many hundreds in the larger orbicular-webbed spiders of the family Argyopidae.
Finally, this region affords us representatives of the order Edentata, in the shape of several species of Manis, or scaly ant-eater.
