Review of the Genus Erebia. 227 
HL. wme may therefore be easily distinguished by this 
character, a useful fact, since some of its varieties closely 
resemble other species. I have found it mixed with 
LH. medusa and £. manto. 
5. HE. lappona (Fig. 35). The clasp hardly 
looks like, or answers to the description of, those of the 
leading species of this group—yet it seems to come here 
most naturally, since it has essentially the same structure, 
but is so much shortened and broadened as to make it 
almost as short and squat as that of Z. afra, which it con- 
siderably resembles. It has no recognisable shoulder, the 
neck is broad and flat, and there is a row of styles at the 
extremity. Though so broad, it is thin, or at least the 
neck is, so that, seen laterally, its outline is not unlike 
that in #. wme, and, though so abbreviated, it really 
possesses the characters of this group. 
Group VI. This group, except perhaps as regards 
E, evias, is not very close to group V, but it agrees in 
having a long clasp, with a long neck. This is cylindrical 
with a terminal cap of styles; the position of the lobe is 
. not very obvious and there is usually an armature of styles 
stretching along the neck and shaft. 
The species here included fall into three divisions, each 
of which is probably so distinct as to be of equal value 
with group V. In fact, this group might very properly be 
made into three groups. 
The species are: a. evias ; 
b. Tossa (ero) ; 
c, embla, cyclopius, disa. 
a,  £. evias (Fig. 36). A rather isolated 
form, in which the typical neuration is for veins 10 and 
7 to arise together. This tendency to incline to Section B. 
probably does not imply any relationship to the forms in 
that section ; the facies of this species is very different, and 
is much that of group V ; besides, the clasp form has nothing 
approaching it in the “whole of Section B, though the 
large area of numerous styles is not without a suggestion 
of some species there. The form of the clasp is that of 
this group or nearly so, but the spines (or styles) are very 
minute, especially on the head, and extend thence as 
a broad band, of a number of rows, towards the base, past 
the position that probably represents the lobe.
