Sphmgidas 
This species, which is allied to the preceding, may be easily 
recognized by its pale, silvery-gray color, by the almost entire 
absence of a dorsal stripe on the 
abdomen, and by the marking 
of the secondaries, which are 
grayish-white, having on the 
outer margin a broad band which 
is black inwardly, fading into 
darkish gray near the margin, a 
median irregularly curved black 
band, and at the insertion of 
the wing a black basal patch. 
The cut (Fig. 24) will enable the 
student to recognize the species, 
which is not common in collec¬ 
tions. The insect is found in 
Kansas and the southwestern States.

This species has been confounded with others, but may easily 
be recognized from the figure which we give in our plate. It 
ranges from Colorado southward through New Mexico and 
Arizona into Mexico.

This common and widely distributed species ranges from 
Canada to Florida, westward to the Pacific, and southward into 
Mexico. Several local races are recognized, that which occurs 
upon the Pacific coast having been named oreodaphne by Henry 
Edwards. The caterpillar feeds upon the wild-cherry, the ash, 
the privet, and other allied plants. The insect is double-brooded 
in the Middle States, appearing on the wing in the latter part of 
May, and again in August.
