194 LLOYD'S NATURAL HISTORY. 



flying Motns. The discoidal cells are closed, and the hind- 

 wings are provided with two sub-median nervures, while the 

 costal and sub-costal nervures are frequently connected by a 

 short cross-nervule near the base. 



This is a very numerous Family, most of the species being 

 either white or yellow, with black markings. Or they may 

 be brown, and occasionally they are marked with red. To this 

 Family belong several of our commonest and best-known 

 Moths, such as the Vapourer Moth, the Brown- and Gold- 

 Tail Moths, &c., and many of them are very destructive to 

 the plants on which they feed. Some of the exotic genera, such 

 as the American genus Eloria of Walker, and the African genus 

 (yj^r^, Boisduval, have extremely delicate, gauzy, and sometimes 

 almost transparent, wings. Apart from the genera with apterous 

 females, the dissimilarity of the sexes, both in form, colour, 

 and habits, is very great in some genera, while in others the 

 sexes differ comparatively little, but the female is nearly always 

 a much stouter-bodied insect than the male of the same species.

This genus may be taken as typical of a very extensive 

 series of Moths (most numerous in the Old World), of com- 

 paratively small size and white colour (more or less smoky on 

 the under surface), with one or two conspicuous black spots or 

 markings. The antennae are strongly pectinated in the males, 

 and the females have a large tuft of wool at the end of the 

 abdomen. The Brown-Tail Moth {E. chrysorrhoea) and a still 

 more abundant allied species, the Gold-Tail Moth, Leucoma 

 similis (Fuessly), may often be seen at dusk, resting in the
