There are numerous references in which the names M, pluvialis 

 (Dyar) and M. pluviale (Dyar) have been used, but it is quite evident 

 from the localities given in these works that M. californicum pluviale 

 (Dyar) is the subspecies involved, so most of these references have 

 not been listed. 



ADULT MALES (figs. 191-196).— Ground color varying from 

 medium orange-brown (figs. 193 and 194) to dark orange- or reddish- 

 brown (figs. 191 and 192), rarely yellowish (fig. 196) except in areas 

 of intergradation where specimens may vary from dark reddish-brown 

 to light yellow. Lines on forewings yellowish. Inner area often somewhat 

 lighter than outer area, median area dark, about same color as outer 

 area, or darker. Hindwings same color as darkest part of forewings, 

 and rarely crossed by a contrasting line. Lower surface of both fore- 

 wings and hindwings about same color as hindwing, and both wings 

 usually crossed by a single contrasting line. Terminalia (figs. 22, 23, 

 47, 48, 67, and 68) as described for the northwestern populations of 

 M. californicum under "comments" (page 128), but sometimes some- 

 what more heavily sclerotized and with the base of eighth sternite 

 sometimes more distinctly three-lobed than in other populations of 

 M. californicum.
