Genus Thecla 



This insect has a wide range, being found from the province 

 of Quebec to Texas and Colorado. It is common in western 

 Pennsylvania. 



(15) Thecla liparops, Boisduval and Leconte, Plate XXIX, 

 Fig. 28, $ , under side; Plate V, Fig. 28, chrysalis (The Striped 

 Hair-streak). 



Butterfly. — Dark brown on the upper side, grayish below. 

 The lines are arranged much as in T. edwardsi, but are farther 

 apart, often very narrow, scarcely defining the dark bands 

 between them. The spots at the anal angle are obscure and 

 blackish. Expanse, 1. 15 inch. 



Early Stages. — Much like those of the allied species. Scudder, 

 in "The Butterflies of New England," gives a full account of 

 them. The caterpillar feeds on a variety of plants— oaks, wil- 

 lows, the wild plum, and other rosaceous plants, as well as on 

 the Ericacex. 



It ranges through the northern Atlantic States and Quebec to 

 Colorado and Montana, but is local in its habits, and nowhere 

 common. 



(16) Thecla chalcis, Behr, Plate XXIX, Fig. 36, 6 ; Fig. 37, 

 9 , under side (The Bronzed Hair-streak). 



Butterfly. — On the upper side uniformly brown. On the 

 under side dark, with a narrow submarginal and an irregular 

 median transverse band, and a pale short bar closing the cell on 

 both wings; a black spot at the anal angle of the secondaries, 

 preceded by a few bluish-green scales. Expanse, 1.00-1. 10 inch. 



Early Stages. — Unknown. 



Habitat, California and Utah. 



(17) Thecla ssepium, Boisduval, Plate XXIX, Fig. 33, 6 ; 

 Fig. 34, ? (The Hedge-row Hair-streak). 



Butterfly. — Almost identically like the preceding species, ex- 

 cept that the wings on the upper side are a trifle redder, on the 

 under side paler; the lines on the under side of the wings are 

 narrowly defined externally by white, and the anal spots are 

 better developed and defined on the hind wings. Expanse, 1.20 

 inch. 



Early Stages. — Unknown. 



This species is found throughout the Pacific States, and I am 

 inclined to believe it identical with chalcis. If this should be 

 proved to be true the latter name will sink as a synonym.
