markings postulated by authors to explain certain phenomena 
of pattern. 
Pseudo-linear arrangements of markings, insofar as they oc- 
cur in the Lycaenidae, must be also briefly noted. The terminal 
line is the only sequence of interspatial markings for which I 
employ the word “line” at all, as it is the simplest term. Al- 
though it may be the remaining maximal limit of an infuscation 
preceding the formation of the first macule, its connection with 
ciliary elements places it in a separate class (submarkings) from 
the macules. It would not have mattered much had I called it 
“limbal” with Herrich Schaffer or “extreme” with Schroder, or 
“marginal” with the British authors. But if I called it “Line I” 
with Eimer (who has eleven of them numbered basad) or “XII” 
with Verity (who has twelve of them, numbered distad), or 
“2 2d” with Kusnezov (who has twenty-two) or “external I” 
with Schwanwitsch (who has three such external ones) or 
“Randbinde I” with Suffert (who has two such “Randbinden”), 
then I would be instantly involved in a wild confusion of man- 
made patterns. I fail to perceive in the Lycaenid wing any sug- 
gestion whatsoever of initial transverse lines or stripes forming, 
or having formed, an integral part of the pattern and lending 
themselves to classification and “homologisation.” In Lepidop- 
tera generally, the limit of a lost ancestral infuscation in any 
place within a given cell, may produce, in combination with a 
similar limit occurring at more or less the same point in an ad- 
jacent cell, what may be loosely termed a line. When this occurs 
in several interspaces without a special macular differentiation 
in any, and is followed by various adjustments and adaptations 
to the distal outline of the wing in the course of more or less 
synchronized stages of posterior and anterior development of 
the termen, then the line may seem very perfect to the eye, but 
it is the result of those processes and not a “primitive” line 
which Mother Nature automatically traced with her brush 
on one butterfly after another as soon as she had stuck on the 
wings. 
It is never the line as such that “breaks” into ocelloid mac- 
ules. Such macules are formed by the initial spread of fuscous, 
or not at all; and sometimes when the latter had been strong 
enough interneurally to span that space, the resulting macule 
may be broad enough to “connect” with any other macule (not
