,., xiair Plumules {Plumulce capillares) {Thanaos tages). 

 These are slender, almost as fine as a hair, and are obtuse at the 

 end. Such plumules are found in the costal fold of Thanaos tages, 

 and on the upper side of the wings in many species of Lyccena. 



(4.) Jointed Plumules {Plumulce articulatce) {Hesperia comma) , 

 which are slender, nearly smooth, and divided into many joints, 

 easily separable from one another. These very remarkable scales 

 are found closely packed together in the small male-brands in all 

 the species of true Hesperia. 



(5.) Bladder Plumules {Plumulce papillosce) {Lyccena icarus). 

 These are small oval or egg-shaped scales, which have more 

 or fewer rows of small bladder-like elevations on the surface, 

 and are found in most species of the genus Lyccena. 



(6.) Dotted 'Plumules {Plumulce j^unctidatce) {Thecla w -album). 

 Dotted plumules are very like ordinary wing- scales, and the 

 whole surface is very finely and closely dotted ; they are always 

 agglomerated into brands, and are found in the species of Thecla 

 and in Colias edusa.
