season of 1893 several specimens of the variety glaucus which were 
curiously splotched with yellow, and is inclined to attribute this ten- 
dency to variation to the comparative drought which characterized the 
summer in Kansas. 
The insect most nearly resembles the black form of gldueus. The 
wings of the left side are black in general coloring. The primary of the 
right side is also black, while the secondary of the same side is a bright 
and beautiful male wing, the yellow being normal in all respects except 
that the four spots on the outer border are narrower than in the normal 
male. The three dark wings are curiously and irregularly splotched 
with yellow, as indicated in the figure. The tails of the two hind-wings

are different in shape, that of the right being the normal male tail and 
that of the left the normal female tail. The reentering excision at the 
anal angle of the secondaries is more pronounced on the left wing than 
on the right, and the orange spot i» larger. The orange spot on the 
upper and outer angle of the secondaries is present on the left wing, 
but is slightly smaller than the normal glaums female, while on the 
right wing it is very minute and resembles that of the male. On the 
undersides of the wings the right secondary resembles the underside 
of the secondary of the yellow male, except that the wings are a little 
more deeply lined with black and above the black margin the orange 
is a little more conspicuous. The underside of the left secondary 
resembles in all respects the underside of the right, except that its
