a Group of Lycaenid Butterflies. 493 
the other species of the group. (See fig. 8, compared 
with wing figures of other species.) 
The appendages are shown in Figs. 33 and 35 (the 
latter more magnified). The hooks remind one of those 
of Plebeiids, but it may be noted that short, thick and 
curved as they are, they are without the definite angular 
end of Plebeiids. 
The most notable structure, perhaps, as marking ZizuLA 
off from ZiZEERiA is the renmrkable form of the oedeagus, 
which is very large, short and thick, with two immense 
terminal, slightly curved sj^ines, very different from the 
single fine, straight spine of the other species. 
In all the rest of the tribe {Zizeeria, Zizina), the 
oedeagus is large, flask-shaped, with a dilated base and 
a narrower neck, terminating on one side in a fine spine. 
This may be seen in several of the figures, where also may 
be noted the very long portion of the eversible membrane 
(vesica of Pierce), occupying the whole neck of the “ flask ” 
(in the position it assumes in nearly all my mounts), which is 
armed throughout its whole circumference by fine spicules, 
looking very like a scaled surface; well seen in several 
of the figures, especially perhaps, fig. 28. 
In Zizida gaika, there appears to be no such armature 
of the eversible membrane, which in truth I have not 
definitely seen, but in one of the large terminal spines of 
the oed^eagus, the upper one in both my figures, there 
is centrally a curious little triangular, flange-like process 
with one margin notched. As this occupies exactly the 
same place in all the specimens I have examined, I take 
it to be attached to the spine and not to a contained 
membrane. This spine is smooth, polished, and seems to 
taper to a point, the other looks very similar, but its lower 
margin is serrated, and it has the appearance of being 
articulated at its base; it may, perhaps, belong to the 
eversible membrane. 
The clasps have much the aspect of those of indica 
if very shortened and reduced, and the upper hairs 
strengthened. It is further to be noticed that the great 
basal hairs have a companion, are much larger and 
stronger proportionally than in Zizina and are not simply 
clubbed by a spindle-shaped expansion at the end, but 
appear to be fluted or grooved for some distance, so that 
the end is broadest at the very end, and then divided by 
the grooves into several portions.
