necessarily of its “own,” i.e ., synchronous series) formed in an 
adjacent cell; or, more seldom, during the process of concentra- 
tion + draining + isolation the macule may steal additional 
pigment from the ground of a neighboring unoccupied inter- 
space and form therein part of its halo. 
Even in the most zebroid species of Catochrysopinoc or The- 
clince , the macules peep through their linear disguise. If on the 
basis of some synthetic “prototype” we tried to classify these 
lines (say Lx, Ly, Lz), we would be continuously mistaking 
proximal and distal parts of split macules for components of 
different linear sets, or, in other cases, would come to the non- 
sensical conclusion that the same macules ( e.g ., the second mac- 
ules of the posterior interspaces) form the lower part of Lx in 
one species, the lower part of Lz in another, and an intermediate 
Ly in a third. The illusion of a stripe in the subfamilies men- 
tioned is due to several variously combined factors. The mac- 
ules in two or more adjacent cells may be bar-like, with halos 
formed only laterally. Sessile third macules (half haloed, i.e., 
only distally) wedged proximally in their interspaces, e.g., in R 4 
(just above the outer part of a split discoidal macule) and in M 3 
(just between the discoidal outer portion and the second macule 
in Cu 4 ), combined with a posterior sequence of second macules 
in Cu 4 , Cu 2 , and A1 may complete the illusion of a stripe cross- 
ing the wing radianally. Moreover, when these macules are com- 
paratively weakly pigmented, the eye tends to confuse them 
with portions of ground color; or a complete transverse sec- 
tion of brown ground between “white lines” (formed by the 
inversely in regard to each other directed half halos of two dif- 
ferent macular series) may be mistaken for a “stripe.” Re- 
markable cryptic phenomena in some genera produce yet other 
illusory patterns, and a “white line” that the eye follows across 
two cells may really consist of a proximal half-halo in one and 
a distal one in the other. Finally, it should be kept in mind that 
among the second macules any three may be always seen in line 
provided that two of them (such as A ± and Cu 2 or M 4 and M 2 ) 
are those which, throughout the family, are more or less linked 
together in their movement distad. Although quite possibly my 
judgment may be affected by the fact that the genus which I 
have especially studied and to which we must now turn is most 
honestly “spotted” — and also by the fact that I am interested 
more in what happens within a given interspace than in the
