Review of the Genus EHrebia. 213 
Section A, the European section, has vein 10 arising 
from the cell separately; the clasp usually has an 
obvious, frequently a long, neck. 
SecTIon B, the Asiatic section, has vein 10 arising 
from vein 7; in the clasp of one or two species only is 
any suspicion of a neck present, and it would not be 
absurd to suspect that the style-bearing surface is the 
head, and that the shoulder is absorbed into the shaft. 
Section A is divisible into seven or eight groups and B 
into two or three. It is as obvious here as elsewhere that 
no linear arrangement is satisfactory. By placing certain 
groups in their most satisfactory linear arrangement, the 
equally real relationship of other species finds no ex- 
pression. Thus, as I have arranged the species, the 
embla group is placed after the last and least typical 
members of the neovidas group, whereas its probable 
alliance is with the earlier forms; if this were expressed, 
L. evias right find a more natural position, ZL. neoridas, 
nerine, embla and evias being representatives of these allied 
branches. The latter members of the neoridas group 
would then come into relation with #. medusa and the 
. eastern group, with which #. embla seems to be in no 
relation. 
The manto or euryale clasp may be taken as the most 
pronounced form of clasp in the first group, which con- 
tains L. ligea, ewryale and vidleri as a first division, and 
the Grass Erebias as the second. In these there is a 
gradation from E. manto and eriphyle with the well- 
marked typical outline, through forms in which the lobe 
or shoulder sinks and disappears, to H. flavofasciata, in 
which from base to head the line of styles presents no 
irregularity. The species are £. manto, eriphyle, melampus 
epiphron, pharte, arete, christi, kefersteint and flavofasciata 
The name “Grass Erebias,” a name I have heard ap- 
plied to these species, on what authority I do not know, 
at first seemed to me rather absurd as all Erebias are 
grass insects. It is intended no doubt to mark them 
as not being rock or wood species; at any rate, a name 
for a group is very desirable if we can get one on any 
reasonable terms. 
These “Grass Erebias” are those that puzzle one in 
the field, and even in the cabinet perhaps, more than any 
others. It is therefore very satisfactory to find that the
