The “Botany Bay Diamond Beetle,” as Donovan described it, _Chrysolophus spectabilis_, is one of our commonest and at the same time one of the most beautiful of our weevils. It has a very wide range all over Australia, and is found wherever the black wattle thrives, but also feeds upon many other species. It is very variable in size, measuring to 1 inch in length; is of a uniform black tint, but so thickly covered with patches of bright metallic green scales, that in freshly emerged specimens it seems more green than black. It deposits its eggs about the butt of the wattle tree buried in the bark; the stout fleshy grubs form irregular tunnels in the wood. The Elephant Beetle, _Orthorrhinus cylindrirostris_, whose stout fleshy grubs do a good deal of damage to citrus trees, has a very wide range over Australia: it is a dark brown weevil, covered on the dorsal surface with fine buff and grey scales; the thorax is covered with irregular bosses which form ridges on the elytra. It measures about ½ an inch in length, and has a long slender snout turned down in front, and very long fore-legs terminating in large feathered tarsi; in its native state it feeds upon gum trees. _O. klugi_ is a much smaller species that feeds and breeds in wattles, but is also known as an orchard pest, infesting the canes of vines, and also eating the leaf buds.

It is a rare insect as a rule, ranging from Pine Mountain, Queensland, to the Clarence River, N.S. Wales; but many years ago Masters when collecting in the north came upon a large dead pine tree in the scrub literally covered with hundreds of these great weevils boring into the dead timber with their long slender snouts, making a distinct scratching sound. It is therefore probable that they are confined to the strip of country where the Hoop or Maryborough Pine grows, and breed on it. [Illustration: =Fig. 86.=--_Myrmacicelus formicarius_ (Chev.).
