LEPIDOPTEROLOGY.—-TWO NEW EUROPEAN LYCAENIDS. 7 
AnproconiaA. Rough sketches x about 400. 
Fig. 1. Plebeius ligurica, usual form 11 rows of dots, type and Swiss. 
Fig. 2. Plebeius ligurica, one Swiss specimen has most scales like this, 
12 rows of dots. : 
Fig. 3. Plebeius argus (argyrognomon), most specimens have the majority - 
of their scales like this. 
Fig. 4. Plebeius argus, a form dominant in one specimen from a locality’ 
from which five other specimens agreed with fig. 3. , 
Fig. 5. Plebeius argus var. nivea (Piynwald). 
Fig. 6. Plebeius argus var. belliert. 
Fig. 7. Plebeius sareptensis. 
Fig. 8. Plebeius melissa. 
Fig. 9. Plebeius micrargus, a form found in this species, but not seen in any 
other, the majority of the scales are much more like those of 
melissa. : 
I add rough outline sketches of the androconia to show both the 
general form in eaeh species, but also to show how much they vary in 
each species. These sketches are approximately to scale (about x 400). 
Their individual errors as to form and size are well within the limits 
of variation in the several species. Fig. 1 shows the usual form in 
ligurica from Switzerland, with which the Cernobbio type form agrees. 
But one Swiss specimen has most of the scales of the form in fig. 2, 
which is beyond the average form in argus and approaches micrargus. 
Fig. 8 is an average argus, with which nearly all Swiss specimens 
agree, as well as armoricana and the Pyrenean form. Five specimens 
from Val Veni agree very closely, but one specimen has most of the 
scales, as in fig. 4, again approaching fig. 2 and fig. 9. Fig. 5, var. 
nivea, 9 ribs, and fig. 6, var. bellieri, 10 ribs, are very close to fig. 3, 
but with a trace of tendency to figs. 2 and 6. Figs. 7, 8,and 9, sarep- 
tensis, 13 ribs, melissa, 14 ribs, and mierargus, 1% ribs, seem sufficiently 
different, but my series is too short to allow me to assert this posi- 
tively. As regards micrargus, the androconia show a range of varia- 
tion that strongly supports the view that little material can be found 
in them for specific definition. The scale sketched is of a form 
numerous in the specimen from which it is taken, and I have seen 
no such scale on any other form, but the same specimen presents scales — 
such as are\ more characteristic of each of the other species dealt 
with, argus, liqgurica, sareptensis, and melissa.
