These slnt^ilar niuths an- lialr}- likt* the arcliam ; but the female, Iteinq wingless, Is 

 always found ujK)n or near the ct»coon fr»m which she has escaiw*!, and hovering around 

 her is the male or mate. When at rest, the forelegs are extende<l considerably forward ; 

 while the win:?!, sloping but little, are folded together over the l>uck. 



Some of the fiinales of this fmnily are provided with wings, though only imperfectly, 

 as they tly but sluggishly. The males are diunial, and tly during the day in Mrarch of the 

 females. 



The caterpillars are also jteculiar, In-ing half nakr<l ; and the covering of the remaining 

 portion consists of long tufls of hairs growing from the sidi-sof the lM>dy,and from warts, 

 of which there are some six or eight. Some have four or five thick tufts of hair ujion the 

 back, cut short ami even ; and fV»>in the extremities, or from the first ring, two beautiful 

 tuns of long hair prnject forwiinl in the form of f»*elers. 



Thes«- cutrrj>illnrs are railed tussockt, from the tufts upon thrir l^cks. They resort to 

 trees and vines of different kind<,and feed nfH.n their leav«-s. Their cticoons are ovni.thin, 

 and made of silk interwoven with the hair of their Itodies. They are more or less injurious
