BUTTERFLIES OF MONTANA. 



115 



Genus COENONYMPHA, Westwood. 1 



The Ringlets. 



Small Butterflies. The costal, median and sub-median veins are all 

 strongly swollen, as may be seen in figure 89. The palpi are very heavily 

 clothed with hairs, the last joint quite long and porrect. The antennae 

 are short, delicate, gradually but distinctly club-; 

 bed. The eyes are naked. Both wings on the 

 outer margin are evenly rounded. 



This genus is distributed throughout the tem- 

 perate regions both of the old and new world, 

 and includes in our fauna a number of forms, the 

 most of which are peculiar to the Pacific coast. 

 They are very variable as to the number of spots 

 and ocelli, and vary greatly in the color of the 

 under side. It is no infrequent thing to find the 

 ocelli and spots differing on the two sides of 

 the same insect.

the hind margin; abdominal margin and base dark gray; near the hind 

 margin and parallel to it is a series of six black dots, sometimes obsolete, 

 usually with white pupil and broad yellow iris; near the base two irregu- 

 lar pale brown spots, and midway between the base and hind margin a 

 sinuous interrupted ray of same color, extending nearly across the wing. 

 Female like the male.
