(cha, "} 
longer and narrower and continue so up to the termen; 
underneath these is a layer of short broad scales, almost 
the shape of a Swiss cowbell, which have four deep longi- 
tudinal ribs, the apices being very slightly hollowed between 
them and the whole surface finely shagreened. These scales 
are by no means flattened but are corrugated, as they appear 
to rise and fall alternately with the ribs; together with these 
are also similarly shaped scales which are very finely ribbed; 
these however seen under transmitted light are yellowish- 
tawny and not quite clear and transparent as are some of the 
former ones. The cell and median area are covered with 
bluish scales, similar to those in the subcostal area but slightly 
shorter, and tapering rather more widely to the apices which 
are less deeply scalloped; many of these scales appear to be 
‘fluted ” and to be finely shagreened; the basal area below 
the cell and on the fold is clothed with the two kinds of shorter 
scales already referred to, but these are succeeded by the 
longer and broader pattern just described, whilst the post- 
median and terminal areas are covered with a scale of moderate 
length, of even width, rather broad, with more or less even 
apices, underneath which is a layer of the bell-shaped scales 
previously mentioned. The ‘“‘ blasenschuppen”’ are entirely 
different from those in boeticus and are very Celastrinid in shape 
and quite so in sculpture; whilst that genus has somewhat 
of a bell-shaped pattern, this is more scallop-shaped, but 
with straightish sides, tapering wider to the evenly convex 
apex, it has ten and eleven rows of reticulations, and the 
scales do not appear to be uniform in size, some being smaller 
than others; all are somewhat longer than broad, but very 
many are decidedly longer than they are wide. The scales 
of aratus are very closely similar to those of aelianus as also 
are the ‘“ blasenschuppen”; these however have twelve 
rows of reticulations as a rule, and the base is squarer 
than in the other species. Whilst the ordinary scales of 
elpis are quite similar to the others, the “ blasenschuppen ”’ 
are recognisable at a glance, for they are double the length 
of the others though similar in sculpture and general shape; 
there are however only ten rows of reticulations. 
The genus Thysonotis is also furnished with “ blasen-
