 Figure 335 is the typically colored male of the West Coast, and 

 Figure b following is of an example taken in the extreme eastern 

 part of its range, and shows much bronze-color; Figure a is an 

 average specimen, showing the white dots crossing the wing ; some- 

 times these dots are on both wings, or on either. These white dots 

 are the line of separation between Dumetorum and the following, 

 Affinis. 



336. Thecla Affinis.

 Affinis is a variety of Dumetorum, in which there are no white 

 dots on either wing on under side. There are but few examples 

 that are fully and fairly marked with the dots across either wing, 

 most specimens have one or more dots on one of the wings, but in 

 that case they are a sort of intergrades, belonging to neither form. 



337. Thecla Apama. 

 No figure. 



Apama is an Arizona species resembling Dumetorum, on 

 under side greenish in color, and having a more elaborate orna- 

 mentation. It is properly a Mexican species, only in limited num- 

 bers coming across the line. 



Genus CHRYSOPHANUS. 



A group of sixteen species belonging to the West Coast, larger 

 than the Theclas or the Lycaenas, and of apparently intermediate 

 structure; generally reddish males and yellowish females, 

 freckled above and beneath with black spots, and figured with 

 colored lines and lunules. At one time these were considered as 

 Lycaenas, and were listed with them.
