In this geiras (named from Xatf/os /latry, and 
xa/j/sr^ a norm or caterpillar) the antennae ai-e 
hipectinated in the males, and merely serrated in 
the other sex. There are neither mandibles nor 
suctorial trunk, hut two short hairy palpi are ob- 
servable, composed of tliree 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 uith hairs. Four 
species are recorded as British, all of which are of 
a reddish-brownish colour, with ti-ansverse wliitish 
bands. The species figured to illustrate the genus 
is the most common of the whole. The male is of 
a deep feiTuginous or chestnut-brown, with an 
ochreous yellow band running across all the wings
