. Australian insects. Insects. 366 liOMOPTERA. in the larval state, others are naked and cling to the under surface of twigs and leaves. The larvae of the gall-makers are broad, oval, flattened creatures, covered with a mealy secretion, the outer margin of the dorsal shield in each case being fringed with fine regular ciliae. Most of the perfect insects are thickset; they range from chestnut brown to reddish yellow; and have clear transparent wings. Trioza carnosa makes a large, oval, fleshy, brightly tinted gall with an irregular opening at the summit, often covering and aborting the foliage

T. hanlsine has a tiny, naked, yellow larva covered with silvery down; it is a rare insect found on the under surface of the honeysuckle leaves. Nearly all these species have been collected within.
