contents are thrown out of the pit, which is then kept clear of refuse.
A full-grown larva digs a pit about 2 in. deep and 3 in. wide at the
edge. The pupa stage of the ant-lion is quiescent. The larva makes a
globular case of sand stuck together with fine silk spun, it is said,
from a slender spinneret at the posterior end of the body. In this it
remains until the completion of the transformation into the sexually
mature insect, which then emerges from the case, leaving the pupal
integument behind. In certain species of _Myrmeleonidae_, such as
_Dendroleon pantheormis_, the larva, although resembling that of
_Myrmeleon_ structurally, makes no pitfall, but seizes passing prey from
any nook or crevice in which it shelters.

The exact meaning of the name ant-lion (Fr. _fourmilion_) is uncertain.
It has been thought that it refers to the fact that ants form a large
percentage of the prey of the insect, the suffix "lion" merely
suggesting destroyer or eater. Perhaps, however, the name may only
signify a large terrestrial biting apterous insect, surpassing the ant
in size and predatory habits. (R. I. P.)

ANTOFAGASTA, a town and port of northern Chile and capital of the
Chilean province of the same name, situated about 768 m. N. of
Valparaiso in 23 deg. 38' 39" S. lat. and 70 deg. 24' 39" W. long. Pop.
(est. 1902) 16,084. Antofagasta is the seaport for a railway running to
Oruro, Bolivia, and is the only available outlet for the trade of the
south-western departments of that republic. The smelting works for the
neighbouring silver mines are located here, and a thriving trade with
the inland mining towns is carried on. The town was founded in 1870 as a
shipping port for the recently discovered silver mines of that vicinity,
and belonged to Bolivia until 1879, when it was occupied by a Chilean
military force.

The province of ANTOFAGASTA has an area of 46,611 sq. m. lying within
the desert of Atacama and between the provinces of Tarapaca and Atacama.
It is rich in saline and other mineral deposits, the important Caracoles
silver mines being about 90 m. north-east of the port of Antofagasta.
Like the other provinces of this region, Antofagasta produces for export
copper, silver, silver ores, lead, nitrate of soda, borax and salt.
Iron and manganese ores are also found. Besides Antofagasta the
principal towns are Taltal, Mejillones, Cobija (the old capital) and
Tocopilla. Up to 1879 the province belonged to Bolivia
