 the cast skins of Lv. and of its own earlier stages, each skin is bordered 

 by these scales, which entirely cover the whole creature including Rost. and 

 legs, except the larval skin ; each nymphal skin also carries 4 apophyses from 

 which spring very long nairs, these are usually, but not invariably, broken 

 off from the cast skins. — Im. L. ca. 1 mm.
