been occasionally reared in this country from caterpillars found 

 in imported tomatoes. 



The Saxon {Hyppa rcctiliued). 



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, hQ^vhexxy {A rctostap/iylos uva-nrsi)^ 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 

 plentitiful, however, from Perthshire to Sutherland. Kane 

 notes it from Tore Wood, Killarney, near Galway, and Clon- 

 brock ; and that the form is identical with that from Aberdeen 

 named scmiviri^ata^ Tutt. The range abroad extends to Siberia 

 and Amurland ; and the North American, xyluioides^ Guen, 

 seems to be a form of the present species. 



The Figure of Eight Moth {Diloha aeruleocephahi). 



The greyish-centred white marks are the chief features on the 

 brownish fore wings of this moth (Plate 127, Figs, i, 2). The 

 first one, or both when quite apart, is very like the figure 8 ; 

 sometimes these marks are united, and form an irregular blotch. 

 Rarely the area between the black lines is dark and the marks
