pseudo-plumule is less abundant in the secondaries than in 
the primaries. 
It has been said that Lampides aratus has “ plumules ”’ of 
a similar shape to boeticus; this however is an error, the 
plumules of all the species of the genus Lampides (7. e. of the 
aelianus group) that I have examined having short “ blasen- 
schuppen”’ of the Celastrina type, in fact I am at present 
unaware of any “ blasenschuppen”’ similar to boeticus with 
one exception and that in a genus not nearly related to it; 
the species in question is Uranothauma falkensteim, the scale 
being an almost exact replica of the one found in boeticus only 
probably less than half its size; it is the same shape, has 
similar striations, with the attachment peduncle at the thick 
end, but the scale is finer in texture as also are the striations. 
The most interesting feature of these “ blasenschuppen ” 
however is that they are not distributed generally over 
the greater part of the wing as is usually the case, but are 
restricted to certain defined interneural lines and are of a 
purplish-blackish colour; mixed with them is another mimic 
‘““ blasenschuppe ” of the common “ battledore ” shape with 
four parallel ribs; these are numerous and do not occur apart 
from the long ones just described. These are perhaps with 
the large sex patch obtaining in the other species of this 
genus the simplest form of sex mark in the Lycaeninae, with 
the exception of the Strymonidae; it is also worthy of note 
that the ordinary wing scales are among the simplest of the 
group being plain oblong scales evenly terminated, the same 
scale being distributed over nearly five-sixths of the wing, 
those on the fold and in the costal area being only a narrower 
and longer modification of this pattern. The usual deeply 
serrated or scalloped apices are almost, though not absolutely, 
absent in this species. 
Polyommatus menalcas presents several peculiar and interest- 
ing features, this being a species in which the median area of 
the primaries is largely covered with soft hair-like scales, 
and it was with considerable interest that I examined it. 
The base and costal cable are amply covered with the long, 
fine, hair-like, bluish-white scales common to most of the 
genera Plebeius and Polyommatus, but the soft brown hair-
