rather widely separated, and two olive-grey trans\-ersc bands ; hind-wings white, with an 

 indistinct and partly double grey line. Expands about i| inches. This species is much more 

 slender than Sociaria, and has more resemblance to a small BoaiDiia.) 



C.KNUS XLIX. — BO.\KMI.\ (TK.). 



I^argc moths, rarely below the middle size, and moderately slender ; the wings dusted with 

 grey, with a more or less distinct pale submarginal line, which is generally zigzag ; and the fore- 

 wings with two dark transverse lines, the second running from or beyond the middle of the 

 inner margin nearly to the tip, and then turning again towards the base ; it is often dentatcd, 

 and is continued on the hind-wings as well as the central shade, and the line on the hind-wings 

 either meets the second line of the fore-wings on the costa, or is set considerably further back- 

 The hind-wings are rounded, and the costa is only slightly, if at all, longer than the inner 

 margin ; the first joint of the front tarsi is very long. The larva; are slender, and are generally 

 furnished with protuberances of various kinds. The moths rest on tree-trunks, with their wings 

 extended flat. They may be divided into sev^eral sections. 

 A. — The antenna of the males pectinated to the tips. 



*i. B. Lichcnaria (Hiibn.). — Wings varied with pale grey and greenish, the fore-wings with 

 two black transverse lines bordered with white, the second sharpl)- dentated and ci^ntinued on 

 the hind-wings. Expands from i to i] inches. Common in Central and Southern Europe in 

 July and August. The larva is humped, and is \aried with white and green, like the lichens 

 on which it feeds. It may be found in May and June. 



B. — The antenncE of the males pectinated, but simple or serrated toivards the tips. 

 *2. B. Viduata (W. V.). — -Wings white, finely speckled with black, the fore-wings varied 

 with brownish, with the central shade broad and black, and with two black transverse lines, 

 the second slightly dentated, and thickened on the nervures. Expands about ij inches. 

 Common in Central Europe in May and June. The larva has a double hump on the 6th 

 segment, and is varied with paler and darker brown, like bark. It feeds on lichens growing on 

 trees, in autumn. 



*3. B. Glabraria (VV. V.). — Wings white, thinly and finely dusted with black, the fore- 

 wings with four blackish spots on the costa, a large black central spot, and two black 

 transverse lines, which arc not dentated, and are often indistinct. E.xpands from i to i| 

 inches. Common in Central Europe in June and July. The larva is verdigris-green, with 

 three black lines on the back, and black spots on the sides. It feeds on lichens in May. 



*4. B. Cinctaria (VV. V.). — Wings with the hind margin slightly waved, pale grey, thickly 

 dusted with brown ; the fore-wings varied with brownish, with rather long black central 

 rings, two black scarcely dentated transverse lines, and a light subterminal line, shortl}' and 

 evenly dentated; the first segment of the abdomen white. Expands from \\ to \\ inches. 

 Common in Northern and Central Europe and Northern Asia from April to June. The 

 larva is green, with many white longitudinal lines, of which those on the back are most 

 distinct. The larva feeds on St. John's wort and wormwood in June and July. The moth is 

 figured at PI. 46, Fig. 2. 



*5. B. Repandata (Linn.).— Wings with the hind margin strongly waved, ashy-grey, varied 

 with brownish and rusty-yellow, and dusted with darker, with a light, irregularly-dentated 

 subterminal line ; the fore-wings with two black transverse lines ; the second strongly and 

 irregularly curved, and connected with the subterminal line by a dark grey spot above the
