2a. Thoracic legs present, either normal in form and distinctly seg- 

 mented or modified; if modified, fleshy or conical, if conical, head 

 and body depressed 3 



2b. Thoracic legs not distinctly segmented, mamma-like or wanting; if 

 mamma-like, head and body never distinctly depressed 17 



3a. Thoracic legs normal in form, not seta-like, rarely nipple-shaped; 

 prologs usually present; subanal appendages wanting; antennae 

 usually with less than 7 segments 4 



3b. Thoracic legs seta-like; prolegs wanting; subanal appendages pre- 

 sent, setaceous; antennae very long, 7-segroented.

Around 100 species have been de- 

 scribed. The larvae roll leaves or 

 spin webs usually live gregariously 



together. A few ore serious orchard
