groups are now by general consent brought together in this one fam¬ 
ily, and they agree in the following points : The head is small in 
comparison with the body, apparently sunken into the thorax, the 
mouth parts small or wanting, palpi seldom projecting any in front 
of the head, antennae broadly pectinate. Body large, shoulder tufts 
prominent, sometimes the long hairs covering the top of the thorax. 
Wings often broad and falcate. 
The larvae are thick, usually more hairy than other moths, and 
often covered above and on the sides by wart-like tubercles from 
which arise tufts of simple spreading hairs. The hairs of many spe¬ 
cies are so roughened by minute points that in constructing cocoons 
the caterpillars weave them together, without silk, like felt. 
While many of the species are ranked among the injurious insects, 
some, as the silk-worms, are beneficial, as upon them depend the silk 
industry that is carried on in various parts of the w’orld. 
Utetheisa bella, Linn. 
Expands from an inch and a half to one and three-quarters. The 
fore wings are yellow, crossed by white bands containing black dots. 
Hind wings scarlet, edged with a black outer border, the inner edge of 
which is irregularly notched and toothed. This is known in, Harris 
and the other older authors as Deiopeia bella , or the Beautiful Deiopeia, 
Common from July to September.
