We now come to an anomalous group, whose exact place in the classification of Lepidoptera has puzzled entomologists, but which is usually placed at the end of this family. These are the CRYPTOPHAGINAE, whose larvae, naked, slender caterpillars, live in shallow chambers or short tunnels in the branches of the smaller forest trees. They cover the entrance to their burrow with a screen of loose silken web covered with gnawed bark and droppings. Resting during the day, they come out at night and, biting off some of the leaves, drag them down into the burrow (the ends often sticking out through the web) to feed on at their leisure. When full grown they pupate within the burrow. _C. unipunctata_ is a very handsome satiny white moth about 1½ inches across the wings; the fore pair each have a single black dot in the centre; the abdomen is black fringed with yellow hairs forming a tuft at the extremity. In its native state the caterpillars feed upon the branches of our common honeysuckle (_Banksia serrata_), but have a very great liking for the branches of cherry trees in the orchards; where neglected, they often kill large branches by their attacks. _C. irrorata_ is a larger moth, measuring up to 2 inches across the wings, the fore pair being very broad and square at the extremities; they are of a uniform greyish brown, slightly mottled with a darker pattern round the outer margins; the hind pair are silvery brown fringed round the edges. The larva feeds on the stems of _Casuarina_. _C. rubriginosa_ is nearly as large as the last; the fore wings are reddish brown. There is a salmon tint on the thorax extending on to the base of the fore wings; the hind wings are brownish yellow. The larvae feed in the stems and branches of several species of _Acacia_. Family 17. Grain and Clothes Moths. MICRO-LEPIDOPTERA. In concluding the Lepidoptera I place these families, often grouped together under the comprehensive term _Micro-lepidoptera_, in the above division. Most of these moths are small, but the group is very important in that it contains some of the most destructive pests of grain, cloth, &c., and they are world-wide in their range. Meyrick has made a special study of these moths, and has classified and described an immense number in a series of papers in the Proc. Linn. Soc. N.S.W. 1878–1904. The larvae of the different groups are usually slender naked grubs with a few scattered hairs, and are sometimes legless; but others again have from 14 to 18 pairs of legs. They feed upon all kinds of material, sometimes forming tubular cells out of their food, while others move about quite freely. The moths may be obtained by beating or shaking bushes, or breeding them from the material among which they feed.
