part, stopping or diminishing in number at or beyond limit II 
(■ i.e . the limit corresponding to the emplacement of second mac- 
ules, q.v., of the underside) but sometimes just reaching in 
hindwing (where however they are somewhat less conspicuous 
throughout than in the forewing) limit I (i.e., the limit corre- 
sponding to the emplacement of the semimacules q.v. of the 
underside). Above RM in forewing mainly along veins Sc, R x , 
R 2 , and R 3 , agglomerating on their slopes (giving the vein a 
pinnate appearance) when the overlay is dense enough to elimi- 
nate the vadosse in the costal area which then seems, especially 
in freshly emerged specimens, rather densely powdered with 
white (costal pulvis) . 
2. Male androconial scales : a microscopical character: mi- 
nute battledore-shaped scales, in outline, size, length of pedicule 
and number and density of “knots” varying in individuals of 
some forms, racially more or less constant in others (especially 
in stunted or overdeveloped forms), and often duplicated by 
specifically different races (and thus lacking the specific im- 
portance assigned them by Courvoisier, 1917, on the strength 
of scanty, and more or less misidentified, European material). 
3. Costal fringe: short hair scales (allied to the male hair- 
scales) in both sexes rimming the costa with white and very 
conspicuous in specimens with a strongly pigmented costal 
vadum (IV, 5). 
4. Basal cilia: long and very long silvery white, bluish or 
drab hairscales clothing basally the upperside of the hindwing 
(reduced in forewing), sweeping in a distal and then downward 
direction across the proximal part of cell RM, extending rather 
far into interspace Cu x where they just reach limit II, still fur- 
ther in Cu 2 + 1A (almost to limit I), and spreading from base 
into 2 A and 4 A, where they stipple the scintillant pulvis of the 
dorsum. 
5. Dorsal cilia: white, or producing on the upperside a light 
blue effect as if daintily dyed. Springing from a very faintly 
fuscous dorsal margin and sometimes slightly infuscated them- 
selves. Equal to about 10 s.l., somewhat shorter in forewing. 
6. Terminal cilia as seen from the underside: long hairscales 
(equal to about 10 s.l. in forewing and to 12 s.l. in hindwing) 
attached to the termen, proximally denser than distally; silvery 
white or with slight bluish or mother-of-pearl reflections in 
certain lights; sometimes, especially in females, more or less
