Review of the Genus Erebia. 225 
2. E.margarita. I have had no opportunity 
of examining this form; it is certainly very close to 
neorulas, 
3. EL. zapatert (Fig. 27). This is a derivative 
of neoridas, but is quite distinct. The shoulder, though 
represented by a prominence, is quite devoid of styles and 
the neck is extremely slender, and, being as long as in 
neoridas, has the appearance of great length. 
b. 1. EL. pronoe (Fig. 28). When the append- 
ages are so much alike, and when we cannot separate 
neoridas from pronoe by them, it may appear presumptuous 
to say that H. pitho, almangoviae, &c., are the same as 
pronoe. Still this is, I think, justified, as all these forms 
are not sufficiently distinct to deserve specific rank, unless 
it be clearly shown by the appendages to exist; whereas 
the reverse is the case. 
2. E. scipio (Fig. 29). This appears to be a 
derivative of L. pronoe; the clasp is rather more massive, 
and the shoulder is represented by a decided sharp tri- 
angular projection ending in a double spine, with further 
‘spines along the margin towards the base and, in one 
specimen, with a few spines along the neck, an exception 
to the rule in the group. 
3. EL. lefebvrer (Fig. 30). This species ap- 
pears to be a variant from #. pronoe. The clasp is ex- 
tremely variable in the development of the shoulder and 
its styles, and some of the forms are quite indistinguish- 
able from those of pronoe; others are close to scipio in 
form. In none do the forms go beyond what one might 
expect to meet with in a long series of pronoe. 
In his able discussion of #. melas, Calberla does not 
handle this point more than is necessary to show that the 
Campiglio variety is abundantly distinct from this species, 
nor does he do much more with melas from Eastern Europe. 
In doing this, he has done what he set out to do, namely, 
to prove that melas from Campiglio is £. glacialis, var. 
alecto; and further than this, he shows that melas from 
Eastern and melas from Western Europe are two distinct 
species and are neither of them glacialis. 
E. lefebvret (Western melas) is certainly very close to 
pronoe, especially in its clasp forms, but must, I think, 
be sustained as distinct.
