costal cable which are longish and narrow, the terminations 
having three short serrations, 7. e. with four teeth; a smaller 
and slightly modified pattern also obtains in the terminal 
area; in the costal, cellular and other areas the scales are 
simple, broader and shorter in the median and postmedian 
regions, narrower and longer in the costal and subcostal 
areas and also on the fold, but all have more or less even apices, 
generally quite even and slightly rounded, but occasionally 
irregular with an indication of dentation, and among the brown 
neural scales many are definitely dentated. Of ‘ blasen- 
schuppen ” however I could find no trace, and this applies 
to all the species of the genus that I have examined both 
Palaearctic and Exotic. 
In Laeosopis roboris the “‘ blasenschuppen”’ are likewise 
absent, the blue scales are small, oval, without any trace of 
serration or dentation of the apices, whilst the brown scales 
are of the normal type with serrated ends. 
In the genus Strymon, in which with a few exceptions the 
coloration is entirely brown, the scales are similar in general 
shape and pattern to those obtaining in other Ruralidae. 
Strymon titus and w-album are typical of all the species, and 
in the latter the costal cable is composed of long narrow scales 
tapering very slightly indeed and having one, two and three 
moderately deep dentations, those with the single dentation 
being mostly on the outer costal edge and largely confined 
to the basal two-thirds; as the apex is approached the scales 
have generally two dentations, whilst those with three are 
found more in the body of the cable; the subcostal area is 
composed of longish broad scales with three and four deep 
dentations among which are a few short broad ones, these 
latter scales also obtain in the cell and on the fold, but with 
the admixture of a certain number of very short broad 
scales, almost round, with a mere indication of slight denta- 
tion; in the postmedian area the scales are longish and 
narrower, with three and four sharp dentations at their apices. 
In general pattern those of S. tutus scarcely differ from w- 
album, but in the detail of apices and relative width of scales 
there are slight differences. We find in this genus perhaps 
the simplest form of sex patch in the whole group; it consists
