This is a southern, unsilvered race of Montivaga in my estima- 
tion. It differs from the typical in the following points : 
TEHACHAPINA MONTIVAGA 
Upper Side — Primaries — Male 
Marginal lines tending to fuse Marginal lines usually double 
Submarginal ovals wider or 
Submarginal oval spots narrow open (variable) 
Extra discal black band nearly 
Extra-discal black band narrow half again as wide 
Upper Side — Secondaries — Male 
Limbal row of round spots re- 
duced, the anterior one larg- 
est 
Extra-discal black wavy line re- 
duced to five discontinuous 
oblongs 
Black markings at outer angie 
of disc reduced 
Limbal row of round spots 
prominent, the posterior two 
largest 
Extra-discal black wavy line 
continuous, sharply defined 
Black marking at outer angle 
of disc a heavy inverted V 
or Y 
Under Side — Primaries — Male 
Ground color, chocolate brown Ground color, creamy - buff, 
with blotches of creamy-buff with shadings of yellow- 
on posterior half 
Extra-discal line wider on tin- Extra-discal line narrower on 
der side than on upper under side than on upper 
Under Side — Secondaries — Male 
Typically unsilvered 
Ground color, brown 
Limbal creamy-buff band re- 
duced and inconspicuous 
Typically silvered although un- 
silvered forms, and all inter- 
prades, occur commonly 
Ground color, creamy-buff 
Limbal creamy-buff band wide 
and clear 
This is not the unsilvered form of macaria, which Wright 
describes under the name of laurina. I have examined a cotype 
of Wright's laurina through the courtesy of Prof. Van Duzee, of 
the California Academy of Science, and find that it does not differ 
from typical macaria except for the lack of silvering — and a 
glance at the accompanying plate will serve to distinguish ma- 
caria from tehachapina. (Plate 1, figures 7-8-9 tehachapina).
