REVISION MALACOSOMA HUBNER IN NORTH AMERICA 123 



Until this can be done it seems best to recognize incurvum and cal- 

 ifornicum as species, name certain geographic subpopulations as 

 subspecies, and refer to other subpopulations with names which have 

 no nomenclatorial significance. Even if it should eventually be shown 

 that these two species intergrade it would probably be best to recognize 

 the low elevation cottonwood populations (incurvum) as a separate 

 species because they are so different in some respects from other 

 populations {californicum) which occur in the same areas and more 

 distant areas.
