In the past this greenish-mottled brownish moth (Plate 126, Fig. 5) appears to have been commoner, and more widely distributed in England than it now is. Wilkes, in 1773, referring to it as "The Wild Arrach," states that it was taken occasionally near London. At the present time the species seems to occur only in the eastern counties, and chiefly in Cambridgeshire. In June, 1904 and 1905, specimens (three in all) were obtained at sugar in Huntingdonshire. The caterpillar is ochreous or reddish brown, dotted with white; three dark lines on the back, the central one only distinct. A yellowish stripe along the black-edged white spiracles; head light reddish brown, glossy. It feeds in July and August on orach (_Atriplex_), persicaria, knot-grass, and will also eat dock. The range abroad extends to Amurland, Corea, and Japan. NOTE.--It may be mentioned here that _Prodenia littoralis_, Boisd., an inhabitant of tropical and sub-tropical regions, has {265} been occasionally reared in this country from caterpillars found in imported tomatoes. THE SAXON (_Lithomoea_ (_Hyppa_) _rectilinea_). The brownish clouding, and reddish-brown central band, of this species (Plate 126, Figs. 6, 7) varies in tone; sometimes the band is olive grey and the clouding rather grey than brown. The caterpillar, according to Buckler, varies from dark brown to chestnut, ochreous, and orange browns; the spiracular stripe pale ochreous or cream colour, shading off in the middle to grey brown. It feeds from July to September, or later, on sallow, bramble, bearberry (_Arctostaphylos uva-ursi_), and will eat knot-grass. It hibernates when full grown, and pupates in the following spring. The moth is out in May, June, or July, and is taken at sugar, chiefly in woods. At one time it was found in Yorkshire, but Cumberland seems to be the only English county in which it now occurs. In Scotland it has been taken in the south. Renton states that near Hawick, Roxburghshire, he finds a few at raspberry blossom every year. It is more plentiful, however, from Perthshire to Sutherland. Kane notes it from Torc Wood, Killarney, near Galway, and Clonbrock; and that the form is identical with that from Aberdeen named _semivirgata_, Tutt. The range abroad extends to Siberia and Amurland; and the North American, _xylinoides_, Guen, seems to be a form of the present species. THE FIGURE OF EIGHT MOTH (_Diloba cæruleocephala_).
