ADULT MALES (males in figs. 209-223).— Color highly variable, 

 ranging from dark reddish-brown to very light yellow, but usually a 

 combination of reddish-brown and yellow in varying proportions. The 

 percent of dark males is greater in the northern part of the range. Lines 

 on forewings almost invariably light yellowish except in very light 

 specimens; rarely, the lines may be absent and the specimen may be 

 entirely reddish-brown (fig. 214) or pale yellow (fig. 213). Median area 

 nearly always the darkest area; inner and outer areas usually about 

 the same color, or outer area slighdy darker. Hindwing usually darker 

 than forewing, about the same color as darkest part of forewing, and 

 often crossed by a yellowish band of scales. Lower surface of both wings 

 about the same color as upper surface, but tending to be darker overall, 

 and both wings crossed by a single contrasting line which is usually 

 lighter. Terminalia (figs. 24, 25, 49, 50, 69, and 70) as described for the 

 southeastern populations of M. californicum under "comments" 

 (page 128).
