IN this genus (named from Xatf/oc hairy, and 

 x#^wr?7 a worm or caterpillar) the antennae are 

 bipectinated in the males, and merely serrated in 

 the other sex. There are neither mandibles nor 

 suctorial trunk, but two short hairy palpi are ob- 

 servable, composed of three joints, the terminal one 

 being very minute. The wings are entire, densely 

 covered with scales, and deflexed when at rest ; the 

 margin with a distinct fringe. The abdomen of the 

 male tufted at the apex and somewhat cleft, that of 

 the female very large and scarcely tufted ; the legs 

 slender and sparingly clothed with hairs. Four 

 species are recorded as British, all of which are of 

 a reddish-brownish colour, with transverse whitish 

 bands. The species figured to illustrate the genus 

 is the most common of the whole. The male is of 

 a deep ferruginous or chestnut-brown, with an 

 ochreous yellow band running across all the wings
