The beetles are found chiefly upon the foliage of young eucalypts, and lay their yellow spindle-shaped eggs in a ring round the small twigs: the young larvae when first hatched cluster together, but as they increase in size they scatter all over the foliage upon which they feed. They are very active, short, stout grubs, with three pairs of well developed legs; when full grown they crawl down and pupate in the soil. The beetles are very convex and broadly rounded; most of them are more or less yellow, brown, or black in tint; some are very richly and delicately shaded with metallic tints, which however unfortunately fade after death. _Paropsis variolosa_, one of our largest species, measures ¾ of an inch in length, and is nearly as broad in proportion; it is of a general yellowish brown tint mottled with lighter yellow and closely punctured; the under surface except the legs is black. _P. alternata_ is a smaller, dark brown beetle, the elytra banded with parallel lines of black and reddish brown: _P. immaculata_ is about the same size; dull reddish brown, with the outer half of the elytra darkest; it is usually found feeding upon the foliage of the black wattle. _P. liturata_ is slightly smaller than the last, with the wing covers irregularly spotted with pale yellow. It is common on the eucalypts about Sydney, and has a wide range over the State. The small green larvae of _P. pictipennis_ feed upon the foliage of _Leptospermum_; the beetle is a small form, dull yellow marked with bright spots, but fades into a dull brown when dead.

(“Agricultural Gazette,” N.S.W.)] The HALTICIDES are popularly known as “flea beetles,” as they have the thighs of the hind legs swollen out into rounded lumps which enable them to jump to a considerable distance: specimens are often found feeding upon sedges about watercourses. _Nisotra submetallica_ is a tiny, shining green beetle, with a light reddish brown head and thorax; it is often a pest in the herb bed, where it feeds upon mint. _Arsipoda macleayi_ is a much larger, deep metallic blue beetle with very large thighs; it has been found eating the surface of vine leaves in the Gosford district N.S.W., and covering them all over with brown blotches.
