In our plate we have given in Fig. 1 a representation of the 

 upper side of the form called discmdalis, which in the central 

 part of the fore wing is broadly marked with reddish fulvous. 

 In Fig. 2 we have a representation of the under side of typical 

 T, damon. With the help of these figures the student may 

 recognize both forms of the species. 



The caterpillar feeds on the red cedar (Juniperus virgiwiand) . 

 It is double-brooded in the North and triple-brooded in the 

 South. The species ranges from Ontario to Texas over the 

 whole eastern hah* of the United States. 



(14) Thecla simcethis (Drury), Plate LXXXV, Fig. 3, d" un- 

 der side (The Brown-margined Hair-streak) . 



Closely resembling in many respects the preceding species, 

 especially on the upper side, but the white band oh the hind 

 wings is straight and the outer margins are heavily marked 

 with bright reddish brown. Expanse 0.85-1.00 inch. 



This pretty species ranges from Texas well into South Amer- 

 ica.
