cottony appendages sometimes along the edge of the body.

six long hairs which are often glued together by white cotton, 
forming a pencil between the anal tubercles. Interior substance 
very oily. Antenne of eight jomts, each bearing hairs. 
Mentum triarticulate, with a few hairs at the tip. Feet 
normal. 
Female of second stage similar, but smaller. Antenne of 
six jomts. Anal tubercles somewhat more conspicuous than in

appendages, distinguish this species from the European D. 
adomdum.
