ADULT MALES (figs. 270-277).— Color more uniform than many 

 other populations of Malacosoma; usually with chocolate-brown mark- 

 ings on a grayish background, the gray often with a faint yellowish tint, 

 and the chocolate-brown usually dusted with grayish scales. Lines on 

 forewings generally appearing chocolate-brown and bordered with a 

 narrow gray or yellow-gray area; usually lines with many indentations 

 along veins which may meet to cut off distinct "islands" of brown as in 

 figure 270. Veins often covered with light scales. Median area often 

 somewhat darker than inner and outer areas, both of which are covered 

 with mixed brown and grayish scales. Hindwing usually darker than 

 forewing, about same chocolate-brown as darkest part of forewing and 

 often crossed by a contrasting line of lighter scales. Lower surface of 

 both forewings and hindwings mixed brown and gray, often somewhat 

 lighter than upper surface; veins usually outlined by light scales on 

 lower surface, and both forewings and hindwings crossed by a single 

 contrasting line. Terminalia (figs. 26, 51, 71) as described for the south- 

 eastern populations of A/, calif ornicum under "comments" (page 128).
