Sphmgidae 



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- FIG. 34. Hyloicus eremitoides.

 Kansas and the southwestern States.

Syn. andromedce Boisduval (partim.); lugens Smith (partim.). 



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.
