Review of the Genus Erebia. 219 
this species are more markedly bent inward into actual 
hooks than in any other species of this group. 
9. E. flavofasciata (Fig. 13). The clasps 
of this species are of much more delicate texture than 
those of the others of this group, or indeed of any Erebia, 
and are easily bent and twisted: they are also narrower 
and, when flattened out, form a triangle about half the 
width at the base of the clasp of £. pharte or arete 
similarly examined. The styles, especially those of the 
neck and head, which are not clearly marked off from 
the body, are smaller and more delicate than those even 
of EF. epiphron. A specimen from the Engadine agrees 
precisely with those from Campolungo. 
Group II. In the next group the clasp has no spines 
ov the body or shaft, and the shoulder, instead of occupy- 
ing about the middle of the shaft, is much nearer the 
head. The combined shoulder and head have a continuous 
margin of spines, the neck being a mere depression in 
this margin. There is a distinct narrowing and bending 
of the body to the basal side of the shoulder, forming a 
‘neck, which, however, is not what I have called the neck 
in the other groups. (Groups I, IV, V, etc.). This group 
includes #. ceto, and an Asiatic species, having severa 
named forms, which are possibly all one species, certainly 
not more than two. I doubt there bemg much real 
relationship between LZ. cefo and this form, but the clasps 
are almost identical. 
1. #. ceto (Fig. 14). This has a_ longer 
central process to the sickle than the others, whilst the 
spinous margin of the clasp is rather shorter and the 
styles somewhat smaller. 
2. H. maurisius (=haberhauert) (Fig. 15). 
This form has a central process of the sickle nearly as 
long as in £#. ceto, and the spinous margin of the clasp 
perhaps a little longer than in &. pawlowskyt. 
3. HL. pawlowskyi (=ethela=theano) (Fig. 
16). This species has a shorter central process to the 
sickle. The differences in the clasp are hardly, if at all, 
appreciable. 
I do not know how much value to attach to the 
length of the sickle in this group; it is possible it may
