Microeschus oblataria, Wlk. (Plate CLXXVI. fig. 17 (larva).) 
Hyria oblataria, WU:. Cat. xxii. p. OGS. 
Larva. Covered with comminuted lichen arranged in tufts upon particular somites. The 
colour of the covering varies with that of the lichen upon which the larva has been feeding. 
The larva itself is cylindrical, smooth, and without any tubercles corresponding to the promi- 
nent parts of its covering, and has three pairs of prolegs. It feeds on minute lichens growing 
upon rocks and trees. If several larvae are confined together without other food they will 
feed on the lichens with which they are covered. The cocoon is suspended by a cable of silk 
beneath sheltered rocks, and is similarly covered with lichens.

disposed over the outer area, leaving, however, an indistinct submarginal band of white 
blotches and a black marginal line. Hind wing ochreous, evenly irrorated with pink and 
black scales ; a white spot in end of cell ; three postmedial white spots, one on the costa, one 
beyond end of cell, the other on inner margin ; a black mai'ginal line.
