The caterpillar has the first and second pairs of prolegs very short, and below the brown-ringed spiracles there is a projecting ridge, fringed with a row of fleshy greenish-white filaments, some of which are forked. Bluish-green, sometimes tinged with ochreous; raised dots, black at the tips, on a base of whitish green; along the middle of the back is a series of darker green spear-points, and beyond this on each side a pale line, edged above by a fine wavy black line, and below by a darker green line; the eighth and eleventh rings of the body darker than the others. (Abridged from description by Buckler.) It feeds on lichens growing upon larch, spruce, hawthorn, sloe, fruit trees, etc., from September to May. The moth is out in June, July, and August, and may be beaten from the branches of trees, and from hedges, but the flushing of a specimen in this way is always a more or less casual event. It has been taken on several occasions at street lamps, and also in illuminated moth traps. In England the species seems to be widely distributed over the southern counties to Oxfordshire and Gloucestershire; and in the east to Norfolk. It has also been recorded from Derbyshire (one), and Yorkshire (two). The range abroad extends to Amurland. {86} THE WAVED BLACK (_Parascotia fuliginaria_). In the shape of its wings and general appearance the dingy insect represented on Plate 36, Fig. 2, would seem to belong to the Geometridae rather than to the present group, and, indeed, has been mistaken for a dark form of _Ematurga atomaria_. However, the long, projecting palpi are evidence of its being a member of this sub-family. The caterpillar, which is moderately stout, and tapers slightly towards each end, has only twelve feet. Ground colour, sooty black, with orange-coloured raised dots, from which arise long recurved hairs. The late Mr. W. H. Tugwell (from whose description of the larva that given above has been adapted), in 1884, was shown caterpillars upon a black sooty-looking fungus (determined by Dr. M. C. Cooke as an effused _Muscedine_), growing in masses on rotten wood in an old wooden building in Bermondsey, near the river. He afterwards reared the moths. The caterpillar hatches from the egg in August, but it is not full grown until May or June, when it spins a fairly compact cocoon of greyish silk, which is coated with particles of decayed wood and dried fungus.
