Genus Hesperia 



$, under side ; Plate II, Fig. 23, larva ; Plate VI, Fig. 21, chrys- 

 alis (The Hoary-edge). 



Butterfly. — The general appearance of the upper side of the 

 wings strongly recalls E. tityrus, but the hoary edge of the secon- 

 daries and the absence of the broad median silvery 

 spot found in tityrus at once serve to discriminate 

 the two forms. Expanse, 1. 65-1. 95 inch. 



Early Stages. — What is known of them may 

 be ascertained by consulting the pages of "The 

 Butterflies of New England." The caterpillar is 

 found on the leaves of Desmodium (Beggar's-lice). 

 The insect is rare in southern New England, 

 and ranges thence southward and westward to 

 Neuration of°the Texas, being scarce in the Mississippi Valley north 

 genus Acbala- of Kentucky, and apparently not ranging west 

 rus ' of Missouri. 



(2) Achalarus cellus, Boisduval and Leconte, Plate XLV, 

 Fig. 12, 3 (The Golden-banded Skipper). 



Butterfly. — The figure in the plate will enable the instant iden- 

 tification of this beautiful species, which, on the under side, has 

 the hind wings banded much as in E. proteus. Expanse, 2.00 

 inches. 



Early Stages. — What little we know of these is based mainly 

 upon the observations of Abbot, and there is an opportunity here 

 for some young naturalist to render a good service to science by 

 rearing the insect through all stages from the egg. The habits 

 of the larva are not greatly different from those of allied species. 



A. cellus is found in the Virginias, and thence southward and 

 westward to Arizona and Mexico. It is common in the Carolinas. 



Genus HESPERIA, Fabricius 



Butterfly. — The antennae are relatively short; the club is stout 

 and blunt at the tip. The palpi are bent upward, with the third 

 joint buried in the scales covering the second joint. The hind 

 wing is usually evenly rounded. In all the American species the 

 male is provided with a costal fold. The neuration is represented 

 in the cut. 



Egg. — Hemispherical, ribbed.
