The pronoe-neoridas section are then all very closely 
allied, whether we make them all one species or several. 
Whilst recognising their close association, I should with 
my present knowledge sustain xeoridas, zapateri, pronoe, 
scipio, lefebvrei as good species. 
c. 1. #. nerine (Fig. 31). In JL. nerine the 
shoulder is represented by a single spine, which is some- 
times wanting, and thus it is easily distinguished from 
any member of the pronoe group. The Eastern melas 
(true melas ?) is a form of nerine. The clasps figured by 
Calberla, and those I have examined, are precisely identical 
with those of nerine. That this is here proof of specitic 
identity follows from the fact, that #. nerine in its easterly 
distribution has a well-recognised variety morula, of which 
many specimens are very close to melas. A few years ago I 
took at Cortina a specimen of Z. nerine, that would be 
difficult to distinguish from melas. This and other dark 
specimens were, like melas, smaller than the nerine with 
which they flew, but with intermediate forms showing 
their identity. It seems that eastwards £. nerine becomes 
smaller and darker till it presents no normally coloured 
specimens and is then in fact melas, 
2. EL. goante (Fig. 32). This is a very distinct 
species, the clasp being not unlike that of nerine, but 
broader and more robust seen from above or within; seen 
laterally, the neck tapers steadily to the head, whilst in 
nerine it preserves its width more nearly throughout. 
. goante is without any representative of the lobe or 
shoulder. JZ. nevine usually but not always has a solitary 
spine or style. 
3. LH. stygne (Fig. 33). In lateral view the 
clasp is shorter and more robust than that of Z. goante, 
narrowing very much just at the neck, expanding very 
much towards the head and having the terminal style 
very large. 
4. E. wme (Fig. 34), This has a clasp not 
unlike that of Z. stygne. If we suppose the neck in stygne, 
instead of expanding again, to continue tapering and to 
terminate in a single large claw-like style, we should 
have the form in wme. This clasp with a solitary terminal 
style is very distinctive, occurring in no other Hrebia. 
though forms very close to it occur in other genera,
