The skin is divided into segments corresponding with those of the 
test, the divisions being marked by lines of spinneret orifices 
which are small and simple. 
In the second stage the usual wavy edge of the genus is not 
generally apparent. 
Adult male somewhat thick and short. Antenne of nine 
joints, the first short and thick, the remainder long and nearly 
equal; each joint after the first has many nodosities, from which 
spring longish hairs. Foot long and slender, especially the tibia.
