Very common from June to September, collecting with Colias philodice 

 and the two species of Phydodes about muddy spots in the roads. Also, 

 often found in fields of clover, upon which plant the larvse feed, or along 

 dry hillsides, where grow the other food plants, species of Desmodhim and 

 Lespedeza.

This, the smallest pecies of Hesperidtv, is a very common butterfly 



from mid-June until October. It is found hovering among the tall grasses 



and sedges which grow along the margins of ditches and ponds. There 



are three broods each season, and chrysalids from the last one hibernate.

A Western species, not before recorded east of Illinois. It occurs in 

 small numbers about Whitings, Lake County. 



PAMPHILA, Fabricius. 



This genus of butterflies, which outranks all others in point of num- 

 bers, is represented in Indiana by twenty-two known species, the major- 

 ity of which occur throughout the State. 



Many species are usually overlooked by tyro collectors, as they are 

 mall in size, dull in color, and are usually seen at rest rather than in 

 active motion. When disturbed, they fly low and but a short distance at 

 a time, moving with a peculiar jerking flight similar to that of the Neonym- 

 phas. In repose the hind wings, instead of being folded above the body, 

 are spread horizontally and meet the fore ones, which are also held in a 

 peculiar position, so as to form a right angle. 



But few are to be found before June 1, but about that time certain 

 species become common among the tall, rank grasses and sedges which 

 grow in damp places and upon which most of the larvse feed. Others
