in the last insect, those in the subcostal area being practically 
similar whilst the majority in the other areas are close also, 
being very simple and broadly spatulate rather than oblong. 
The thick hair-like scales are present in some numbers and 
do not differ from the usual structure and form, whilst the 
‘““ blasenschuppen”’ are decidedly of the Lycaena type but 
are more spherical than those of arion (arion however has the 
longest of the genus); they have nine rows of distinct reticula- 
tions and occasionally ten, this may however be occasioned by 
the position of the scale. 
In both the above cases the ordinary blue scales are very 
different from the Lycaena type. 
In Celastrina argiolus the costal cable of the primaries is 
quite fine, as might be expected with a weakly flighted species, 
and is made up of the costal fringe scales; the subcostal and 
presubterminal areas are clothed with two kinds, a broad almost 
even (in width) long scale, that is irregularly dentated at its 
apex, and has a rounded base with a minute incision for the 
attachment stalk; with this pattern are mixed a few of a much 
longer shape, almost fan-lke, 7.e. narrow at the base and 
widening considerably to the apex, which is tricrenate, the 
central excision being less deep than the outer ones; the 
scales occupying the cell and the fold are decidedly shorter 
in length, tapering slightly from the rounded base to the apex 
which is irregularly dentate or crenate, the postmedian scales 
are of a similar pattern to those in the subcostal area, whilst 
those on the margin are narrower in width, the long fringe 
scales are very narrow proximally and for at least half their 
length, when they rapidly expand, and then, immediately 
in front of the serrated tip, slightly decrease in width; the 
apex is deeply quinqueserrate, the three middle serrations 
being the longest, but not uniform, sometimes one point being 
the longest and sometimes another point. The “ blasen- 
schuppen ” are extraordinarily numerous and large, they are 
cup-shaped, deeply reticulated, with fifteen rows on one 
side. In the secondaries the basal brownish scales are some- 
what squarely formed, having a subtriangular base whose 
apex is the incised attachment stalk; they are very broad 
and short and of even width, the apices being slightly rounded,
