112 CLARK — SOME UNDESCRIBED SPHINGIDAE [PF ZC. 
Calasymbolus myops occidentalis subsp. nov. 
Plate XIII, figure 4. 
Al. ant. long., o', 26 mm.; 9, 31 mm. Al. ant. lat., o', 11 mm.; 9, 
12mm. Marg. ext., 7, 14mm.; 9, 16 mm. 
Habitat. — Glenwood Springs and Boulder, Colorado. One male and 
one female in coll. B. Preston Clark, given me by Dr. William Barnes and 
Mr. T. A. D. Cockerell. 
This form is much lighter in color throughout than the Eastern individ- 
uals. The ground tone of both wings, above and beneath, is light yellowish 
brown, irrorated with pink. The central dot of the spot on the hind wing is 
pale blue, and smaller than in the typical form. The scalloped markings 
of both wings below, which in the Eastern form are blue shading to pink, 
in the Colorado specimens are light pink shading to white. There is a much 
sharper contrast in color between the light and dark portions of both fore 
and hind wing above, and less contrast on the under sides of both wings, 
than in the typical form. The distal margin of the fore wing between SC5 
and M1 is more convex than in the typical form. The light submarginal 
lines on the fore wing are also slightly farther from the distal margin. 
Sphinx dolli dolli Neumoegen. 
Al. ant. long., 9, 27 mm. Al. ant. lat.. 9, 10 mm. Marg. ext., 9, 
15 mm. 
Habitat. — Yavapai Co., Arizona. One female in coll. B. Preston Clark. 
This specimen was taken by Mr. O. Buchholz on July 9, many years ago, 
and came from him to my collection in 1918. 
It is in all respects similar to the male, except that the markings are 
somewhat less distinct. The antennae are light-colored above, and dark 
below, instead of being dark-colored both above and below, as in the male. 
Monarda oryx Druce. 
Al. ant. long., 9, 35 mm. Al. ant. lat., 9, 17 mm. Marg. ext., 2, 
22 mm. 
Habitat. — Mexico. One female in coll. B. Preston Clark. 
The male was described from Jalisco, Mexico, in 1896, but I know of no 
description of the female. The single specimen which I have, was given 
me in exchange by the Brooklyn Museum of Arts and Sciences.
