French, l.c. 16, 12. Color of body varying from greenish gray to dirty brown, ‘very 
largely given by numerous striations and lines; sometimes pinkish anteriorly; piliferous 
spots more prominent than usual, no protuberance on 8th segment, those on the 11th 
variable, head bilobed, greenish gray to brown. Length 2.5 to 3.5 inches. 
Zia is the most variable of all our species. In some cases the prim- 
aries are strongly mixed with blue. I am unable to separate Mr. Worth- 
ington’s examples as proper varieties. If allowed, we must have at least 
50 more names, to express the changes of this variable insect.

July 19, 1875, p. 26. Primaries dark gray, strongly shaded with black, basal dash 
present, t.a. line geminate, diffusely black; M of t.p. line strongly produced, reniform 
clouded, subreniform small, nearly white, a band of brown beyond t.p. line; a faint 
subapical shading. Secondaries like /lia with a shading to the ground color, 
generaily quite violet. Expands 75—80 mm, Habitat, Cal., Northward. 
A species subject to very considerable variation, and in many 
instances very closely approximating certain forms of /éa both in fore 
and hind wings.

Primaries diffuse light gray, with bluish shading, t.a. line edged inwardly with 
white, t.p. line heavy, M broad, but not greatly produced; a diffuse black shading 
running from costa, nearly hiding reniform and ending subapically. Secondaries rather 
dull red. 
One of our largest, rarest, and most scattered species. Expands 
1ooO—110 mm. Habitat Northern U.S.

Primaries close smooth even bluish gray, with basal, apical, and sinus shadings, 
lines fine, but distinct; M of t.p. line produced, a white band from within reniform, 
extending obliquely outward, including subreniform, not reaching inner margin. 
Secondaries rather dull red, median band even, curved, not reaching inner margin. 
Expands 80--85 mm. Habitat Eastern U.S. 
Perpleaxa is slightly more shaded with blue and lighter. 
~ Var. petulans, Hulst. Secondaries yellow, with just a shading of reddish along
