§ I. On Hair-tufts , Felted Patches , and similar Structures 
on the Wings of Male Lepidoptera. 
The males of numerous species of diurnal Lepidoptera are characterized by 
the presence of specialized hair or scales on their wings. I will here bring 
together what I have been able to find on the subject of these structures 
in the few works on Lepidoptera to which I have access. The arrange¬ 
ment of genera adopted below is that of Kirby’s Catalogue of Diurnal 
Lepidoptera , 1871. 
Nymphalidae. 
1. Danainae. 
Danais. —The males have a patch of peculiarly constructed scales on 
the first branch of the median or on the submedian [nervure] of the hind¬ 
wing ; sometimes it takes the form of a sac, which opens on the upper 
surface of the wing, and is filled (at least in dried specimens) with a brown 
dust. 
Amauris [Danais, Sect. 1, Doubld., Gen. D.L.). —The males have a 
patch of peculiarly shaped, closely packed scales on the submedian of the 
hind-wing, not far from the anal angle. 
Euploea. —In the male the inner margin of the fore-wing is usually 
rounded and projects, so as to cover a considerable portion of the hind¬ 
wing. The males of certain species possess, towards the inner margin of 
the fore-wings, one or more short streaks, formed of pale, peculiarly shaped 
scales, presenting a dull, somewhat chalky appearance. That part of the 
hind-wing which is covered by the projecting part of the fore-wing is often 
clothed with scales of a very remarkable shape. They are elongate, hair¬ 
like, basally rather broader, and end in an ovate enlargement, resembling
