(clas, } 
P. admetus is more abundantly covered with these peculiar 
long soft scales than any other European species. What 
shall we find in this species? The scale is of the same structure 
and form as in the two last-mentioned only it is more robust, 
whilst those underlying, and in fact all over the wing in the 
median and post-median areas, are simply developed, with 
evenly rounded terminations. Again however we find an 
interesting character. It has been said, and I do not find that 
it has been pointed out to the contrary as yet, that no brown 
Lycaenidae have “ blasenschuppen”’; admetus however has 
them fairly plentifully in both wings; they are similar in 
shape to its congeners, but smaller, and with finer reticula- 
tions. I found in one specimen two quite abnormal examples 
of this scale, one being more than double the usual size and 
a second very much larger. 
Polyommatus meleager is another species that is densely 
covered with long hair-like scales, as in those we have been 
just considering; the basal ones are of the usual type only 
very long and very fine, but they are succeeded by some of 
another pattern that cover the greater part of the wing sur- 
face, only the terminal area and a small part of the post- 
median subcostal area being free from them. They are 
ribbed exceedingly finely, in colour they are whitish, blue, 
bluish-grey and brown; in size they are very long and narrow, 
being twice to three times the width of the usual basal hair- 
like scales, and in length would exceed ten to fourteen of the 
ordinary wing scales in their usual overlap; in parts they are 
thickly packed together so that it is not easy to see the under- 
lying scales, in which, as would be expected, we find some 
modification; they are finely ribbed, simple in pattern but 
very large in size—apart from those on the veins which are 
very broadly tulip-shaped with waved apices—being unusually 
broad; in shape they are very broadly ovate, the corners 
being rounded off rather too much to be able to call them 
oblong; they are slightly narrower at the base than the apex 
which is evenly arched somewhat; along the inner margin 
the pattern is elongated with a crinkled apex; the terminal 
scales are broadly tulip-shaped with slightly scalloped apices. 
The “blasenschuppen” are of the usual Polyommatus
