It is very variable in size, measur- ing 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 irregu- lar 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 1/7 an inch in length, and has a long slender snout. Fig. 8b.—Chrysolophits xpectabilis (Fabr.)- The Botany Bay Diamond Beetle, ("Agricultural Gazette," ) turned down in front, and very long fore-legs terminating in large feathered tarsi; in its native state it feeds upon gum trees. 0. 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. Eurhamphiis fascicnJatus is one of our largest and most remarkable looking weevils; it measures 2I/2 inches in length, and is of a general black tint, but the greater portion is finely clothed with grey and rusty red scales, which give it a uniform buff tint; it is further clothed vtdth tufts of long soft reddish brown hairs forming a raised ridge down <3ither side of the thorax, and are scattered in rows on the elytra intermixed with small tufts of long grey nairs, giving it a very remarkable spiny appearance. It is a rare insect as a rule, ranging from Pine Mountain, Queensland, to the Clarence River, AYales; but many years ago Mas- ters when collecting in the north came upon a large dead.
