The last group we have to deal with are the Australian stingless honey bees, belonging to the Genus _Trigona_, which range all over Australia. They collect quantities of dark coloured somewhat acid flavoured honey, which they store up in little jug-shaped cells of dark brown wax, forming an irregular comb attached to the walls of the cavity in which they have constructed their hive by a network of irregular rods of wax. They generally choose a cavity in the heart of a large gum-tree with a small opening from the outside, and before commencing to make their comb they plaster up all the cracks and inequalities of the chamber with the sticky sap or gum of the Turpentine Tree (_Syncarpia_). This chamber is usually about the size of a man’s head, and the comb as a rule contains not more than a pint or two of honey. This is the typical nest found in N.S. Wales, but in the tropical scrubs of North Queensland many of them form a small funnel or spout projecting round the opening, composed of a waxy-substance an inch or more in length. As the green tree ants often capture these bees and are always swarming over the tree trunks, this is probably a necessary protection. The honey gatherers of _Trigona carbonaria_, our common species, are black, thickset little bees measuring about ⅙ of an inch in length. They are fearless little creatures when at work, and will allow themselves to be picked off the flowers without any attempt to fly. Several species have been recently added to our fauna, and though Dalla-Torre in his Catalogue places the members of the genus Trigona in the _Melipona_, which until then had only contained the allied stingless bees of South America and the tropics, Cockerell retains them in the old genus, describing a new species from Port Essington, and recording a species known in Ceylon (_Trigona canifrons_) also from the north coast of Australia. Order V.--COLEOPTERA. Beetles. This group is the best known of all the orders, for nearly every entomologist starts collecting as a “beetle hunter.” They are the most frequently observed because they are found everywhere; there is hardly a log or stone that does not shelter some beetle; they infest all kinds of timber, damage the living trees in the forest, devour foodstuffs, stored grain, skins, furs and drugs; others are attracted to all kinds of decaying animal or vegetable matter; while hundreds either in the larval or perfect state are to be found all through the year upon the flowers, foliage, or bark of trees and plants. Thus they are readily collected, and when obtained are much more easy to look after and keep than the more delicate insects, on account of their stout horny structure.
